240sx KA-T wont start

[ChristianKustomz]

Hello there. It's kind of bad when a professional shop has to ask for help. Lucky for me I am not a pridefull man or this would really bother me. Okl here is our current dillema.

We have recently built a KA-T power horse pushing around 510HP with supporting mods. Car was running on a T25, stock MAF and 370cc injectors before we decided to really go all out. ECU was tuned by Redline Performance and was ok. But at least the car ran.

Now we have a new JWT tuned ECU, Nismo matched 740cc injectors w/ lengthened FI wires, T3/T4 super hybrid turbo, N62 orange label 300zx TT MAF and all emissions and idle control systems have been removed. We are using an MSD Blaster coil and Nology hot wires. I know for a fact there is no problem with removing the idle and emission systems. So that is out of the question for possible problems. This is what we have now.

I have tested the spark and have PLENTY of hot Kernals. I have tested to make sure the fuel injectors were getting fed and they are ok. Fuel pressure (with pump on) is 45psi with a rising rate FPR and 24psi with key on accessory. When cranking it shoots right up to 45psi. So it's not the pressure. It does crank but does not start. This makes no sense to me because if you have spark AND fuel there should be happiness in the cylinders but blah is all I have. Does any one have a clue as to what could be the cause of it not starting? I know this is bad being a professional shop and not being able to fix your own SH*T but I have learned some times a fresh pair of eyes can make a world of difference.

I have also swapped ecu's to see if it might be the tune but same thing...nothing.

I have one question...is it possible that the fuel injectors might not be opening? I will be testing them tomorrow to see if they are. If they are then I am right back to where I am now. They are brand new though. I wonder if there is something going on in my wiring harness...Either way some idea's would be great. I have been banging my head against the wall for a while trying to figure out what this could be. Thanks for the help.

Have you pulled any plugs out to see if they're fouled? If you have, did you look in the cyl to see any residual fuel? I had a very similar prob with my KA. To make sure my injector was workin I pulled the plug then tried to start it. Sounds hokie, but it worked- A fine mist of fuel sprayed out the spark plug hole...

[moso]

if you still have side fed injectors you can just unbolt the fuel rail and crank the car to see if your getting fuel but it sounds like a timing problem to me.

[ChristianKustomz]

Nice trick. The fuel injectors are not sending fuel. So I put a volt meter to the fuel injector connectors and no voltage at all. So it is something in my wiring harness. The fuel injectors should be recieving voltage of some sort but nothing. I would have had to check for injector pulse if there was voltage but seeing how there is nothing I have to go back and check the wiring harness for flaws. All 4 connectors are dead which begs the question "HUH"? So now my beautiful harness I so lovingly wrapped all nicely I have to HOCK! Now I am pissed. I will let you know what I find out.

By the way thanks for the tip about removing the spark plug. It was much faster and cleaner - minus the blast of air coming through the cylinder squacking in my eye socket but hey...could have been worse. There could have been fuel blowing with it...OUCH! Either way thanks. That was really a smart way of checking.

[ChristianKustomz]

Hey Moso. That sounds like a really bad idea. Say there is nothing wrong with the fuel system, you now have covered you engine bay and customers car with fuel. It's ignitable. Ours is a show car so that would kill the clear coat. Not to mention dangerous because it could get on you, your hands, eyes etc. Plus why would I want to spend 30-45 minutes disassembling the fuel rail when in 1 minute I can have the spark plug out?I had a guy like you working for me once. He isn't any more. Timing would have NOTHING to do with this. Your just guessing. If the car was working before and the only things changed are the ecu, FI, MAF and FI wiring then it would have to be one of those. Why would timing be an issue? Well long story short the guy who used to work for me fried engines, ran vehicles into things and broke almost everything he touched. I don't mean to bust on you bro but perhaps you should stick to Honda's. I only said that because nothing you have said makes any sense and all sounds like that of a kid or a backyard mechanic. With idea's like that and hair brained guesses it is amazing you have not killed yourself yet. It's probably safer for you to stick with something that does not have a combustable engine...or fuel...or wheels for that matter.

Sorry bro but...DUH!

Ha ha ha.

damn man good luck creating business with people on this forum with that attitude....

He threw an idea out there, maybe had you posted, I fuct with my FI wiring harness we could have said "hey dumbass its the wiring you pros did" or something more witty

sounds like you panties got snatched up your butt crack cause you have to muck with you wiring, which you are not that good at apparently

and btw, show me a 510hp dyno with a f***ing t25 or :ban for being a poser

[ChristianKustomz]

Wow. Perhaps if you learned to read...You know get past your hilbilly redneck up bringing, you would see in my original question I stated that was my "PREVIOUS" set up.

So yeah. I am using a T3/T4 super Hybrid turbo. But again perhaps you should re-READ where I stated "SUPPORTING MODS". I am sorry. Am I speaking too fast or using too large of words for you. Here let me slow it down for you... Y-O-U...A-R-E...A...B-I-G-G-E-R...I-D-I-O-T...T-H-E-N...M-O-S-O!

No one said it was the wiring and I did mention it at the end of my first post. DUH! Again...LEARN TO READ! We have been doing wiring for years and never had a wiring issue so obviously we DO know what we're doing. I have been a certified mechanic for 8 years and have 11 years of knowledge. So please. I know what I am doing and so do my employee's. It could be a fuse or a relay or many other things. We have run this shop for 3 years with no complaints. Your too much of a smart, know it all to be an owner. Your comment is just proof why you are always fired and no one wants to higher you. Your sticking up for a guy who gave an idea that is 1-dangerous, 2-un-thought out and 3-is NEVER a part of the equasion. It only shows you have the brains of a small cashew because you stand by a guy who has no idea what he is talking about either. I would hate to see you or him work on a car cause seriously...guys like you get killed or seriously iunjured because of your lack of experience and professional training. Grant it not eveyone has all the answers or knows it all but someone in my position should have the answers 99% of the time. Now look back at my first comment. I pretty much already knew the answer but I wanted confirmation on the injectors. Thats different from being completely clueless which I am not.

Not my fault. And quite frankly if you can seriously agree with what he said then you have NO room to talk either and should just shut up and sit down. Becuase any one with a brain and who is a "REAL" mechanic would know how stupid and dangerous what he said to do is, not to mention...Timing? It ran before and no one has messed with the timing then why would he think that? People like that just prove their inexperience with vehicle diagnosising. It's just the truth and sometimes the truth hurts. You both must be kids or something. I prefer to speak to people who are older with obvious knowledge.

There is not a professional shop that would ever higher someone who would use an idea like "pull the fuel rail out and let 'er rip".

So no my "panties" are not in a bunch. I wear boxers. I have been in busines for 3 years with out a complaint for a reason...I know how to treat people and I do great work. Thats because I do not listen to people who have no idea what they are talking about. So obviously I DO know what I am doing. If say you were to come to me for work...I would still help you out and treat you well. Just cause we don't agree does not mean we have to be enemies. So before you want to used swear words perhaps you should just mind your own business and not stick your nose where it does not belong.

I am sure he is a nice guy too but I know alot of guys who are nice but POOR mechanics. They think they know what they are talking about but their constant issues with cars shows other wise. Again, I have NO problem with him. I just think he needs to find another profession. Only my opinion.

P.S. I have had and continue to get business from people on this site and they are pleased with my work as well and have no complaints. I can't make everyone happy but my business will not fail because of someone like you. So life goes on.

is it over

[neverlift]

must be busy 'man' to have that much time

[kouki_hmongster]

Reading this thread makes me sick. instead of acknowledging other people who are trying to help, regardless of how stupid some information might be, you end up criticizing. your the worst person ever on nico. First you already have an idea of what your problem is, but you're too lazy to try it. Heck, if you think you know your s*** then stop and use your brain. You're not thinking thats why you made a new thread. I noticed that a lot of shops don't know everything, they big talk thats all.

And the reason why neverlift thought you have 510hp from T-25 set-up is because of "Grammer" . You should reread what you wrote, you were back tracking on the second paragraph.

Lol professional my a** you sir are the example of a loser who i would never let work on my car. A real professional would have read the fsm and then try to trouble shoot the problem in stead of acting like a d!ck, coming on the internet and talking bout people that was just trying to help you d!ck. Just because you have a business that doesnt make you god, welcome to the group. I GOT NEWS for you unless your doing 100 grand or better your not doing nothing d!ck....

[zerepdivad]

It's pretty obvious you don't know what you're doing.... 45 minutes to pull off a fuel rail on ka? Didn't even check the plugs to see if fuel was even getting to them? "professional" shop posting up for help on a forum hah... you don't see AMS on forums asking for help..haha

Sorry you all feel that way. But I guess you all know it all. I am a professional but as stated before NO ONE KNOWS IT ALL. All I wanted was some confirmation to what I already thought it was. Nothing wrong with double checking with another person. I already found the problem and fixed it. Just a simple fuse.

You all can say what you want and mouth off all you want. I am the one with the shop and I am the one who is a professional. When you own your own place, run your own business, higher your own employee's and such then you can say something dirogatory to me. Other then that as far as I am concerned you guys are just another group of people who get all big over the internet but in person is just like everyone else. Grow up.

By the way it was "NOT THE TIMING" and I did not have to dismantle our fuel system to do it. See and all it took was a little simple confirmation from someone else. Thanks for the help. I am very rarely on here so thanks to those who do help intelligently.

Also we have a custom fuel management system on our vehicle. If you count how long it takes to pull it all off making sure not to damage the paint and all the testing and reinstalling it all yes it does take 30-45 minutes.

AMS has posted on blogs. So has JWT and all the others. There is nothing wrong with asking for help when you don't know something. only a fool...AKA "YOU" would not. So what if I ask for help? It is only pride that gets in the way of someone asking for help. If I don't know I want to know. Thats why 99% of the time I do know how to fix and diagnose vehicles. Excuse me for not knowing the other 1%.

THANKS RICKGERHARDT FOR THE HELP AND GOOD IDEA

Ib4 :ban

we understand you have no real car knowledge and wait by your pc to get the answers. Sorry we didnt figure out your vague rambling fast enough. We know you know more than us obviously as you own a business....

lets all try to be adult, this is the big boy forum, you have found your issue without help from us, you obviously dont need our help so why be here if you obviously dont want to be.

good luck with your ventures.

[ka-t4u]

first off all hi! and second i am 19 years old, third i love how you higher people instead of hiring them,lol, call me a young punk who thinks he knows it all as many times as you want, but pulling out a spark plug and smelling/looking/touching for fuel, should be the first thing someone with as much "experience as you" should have thought about,that is after checking everything else that you did check, also just because we are young doesn't mean that we might not have the knowledge or can contribute, because(at least me) we go to people who know more and ask the questions to them, and then use our young, fresh, memory to store the answers in our head.

and by the way I DID pull my fuel rail out, put rags in front of every injector, and had someone hold the rail, while i turned the key, which DID help me figure out that one of my injectors was craping out, and not spraying enough fuel, that was of course after this young "punk" pulled out the plug and it smelled like fuel, but it turns out there just wasn't enough.

please take the advice given to you by other people, as a contribution and a possible idea, and if you do think that they are totally wrong then just tell them, instead of just calling them names and trying to put them down because they might be younger, or may not OWN A SHOP and be so proud of it like you.

i love how you talk about not being so proud yet the first thing out of your mouth(fingers in this case) was: i own a shop, and we have been in business for x amount of time, and "I" have x amount of years of experience.

and please don't tell us, that you solve 99.9% of the problems, because if you did, you would probably be seating next to WD, or spank044, or the rest of the educated mods, giving us answers to questions like yours!!!

again take it as you will, and stop highering techs and start HIRING them.

i know you are just going to come back to me with: o you are so immature you had to make fun about me misspelling a word.... bla bla bla.

if you come here for answers we are all going to try to help you, even the ones that pull out fuel rails to check for injectors, that's why it is a forum, and it is on the internet, which means is public, so anyone out there WILL try to help someone, specially if they have or work on the cars that we own/love/work on too. it's just part of how it works.

stop trying to make other people feel like they are less than you, because you are not more than anyone.!!

I do own my own business google Dollar Square, thats why i said if you aint doing 100 grand our better you aint doing s*** d!ck you try to place yourself on a higher position then everyone else but the truth is you are just as broke as anyone else. A freakin fuse man u sir are one hell of a mechanic like owner like employees your shop will not last long...IBTL

O sorry and that is net not gross. d!ck

*sits down and crack his knuckles*

Wow, you're a friggin douchebag. YOU were the first person in this thread to be arrogant, abrasive and obnoxious. So YOU turned this thread into what it became. I don't care how many businesses you've owned, it doesn't mean your customer service is worth a crap. Obviously you could benefit from basic communication classes, because as an owner you don't talk to people like this.

How can timing be a factor? Wow, not dropping my car off at your shop. What if the dizzy was in 180 out? Probably wouldn't start and it's an easy mistake. Almost as easy as missing the damn fuse

Yeah his idea of unbolting the fuel rail was bad, but you had no right to trash him because he had a bad suggestion. On car forums you get a wide range of people offering suggestions. Learn to take the good with the bad without turning into a total prick. I mean really, a CEO should know all this right? RIGHT???

Oh, I almost forgot to comment on your "SUPER" Hybrid turbo...that thing must be awesome. The last time I read something called "SUPER" it was being sold on eBay. Which makes sense considering you obviously know jack about the KA and turbo's as a whole. I imagine you'll be bankrupt before long, people like you give mechanics a bad name.

NICO is the biggest Nissan Infinity online community in existence, you might have thought of the bad publicity you're now going to get before you trashed our members. I suggest everyone here visit Christians site, http://www.christiankustomz.com/ and maybe pass along how friendly he is to anyone and everyone.

Karma is coming for you Christian.

Have a nice day prick

[Lonismos14]

It should be stated "IM BROKE CAN SOMEBODY PLEASE GIVE ME SOME MONEY, I DONT WANT TO LOSE MY HOUSE AND CARS". Hey christain bow down and tell moso sorry and i will donate 200 from my business to yours its a tax write off...I will be waiting!!!!

[RUHNAy]

shoooots fireeeed !!! RUUUUUUUN BEHIND THE COUCH

[trackslut240]

this is unbelieveable... help or give ideas and get degraded.... unbelievable...

how can people with such short fuses and understanding be in business??

patience advice and support are what u r looking for in any business... not with this guy.... wow

as said by WD karma is a....let me quote in OP's words... "Bi*$ch"

please BAN the imbecile and lock this retahdism....

[Lonismos14]

IBTL I own my own business "As most shops are closing down around this area we have managed to stay open due to wise decision making and good business ethics. However we are starting to struggle. Donations are welcomed. We are a strong supporter of the local community so most often our money goes back into the community such as homeless shelters and families who have lost their lively hoods due to the failing economy. So anything you are willing to donate will be much appreciated. We need donations to help keep us afloat as well. Thank you for your help." Its not the economy yall niggas broke And i see why 210 dollars for a tapped pan the hose only cost 40 dollars. Big rip off Then talk bad about two other shops obviously they doing something right. But let me know when your having your "GOB" sale i buy something

[WDRacing]

please BAN the imbecile and lock this retahdism....

Nah, that lets him off easy In fact, I'm gonna move this to 240Gen The whole community needs to know this guy is a tool.

Oh FFS he replaced the S in his name to a Z, you can't possibly expect him to be mature...

[baron_harkkonen]

IBTL WD, you sir, are my new hero! Who the F**K does this guy think he is? "I know 99% of the answers." Then maybe he can answer why the h**l he's such a doucebag. I mean seriously, he's got how many years of exp? He couldn't even figure out a small fuse problem. I'm no "professional," but even I could have found a freakin wiring problem. The guy needs to grow a pair, own up to bein a complete idiotic f****n moron, and reevaluate if he really wants to be ownin a shop. I don't think that his panties got wound up his a**, I think he's mad cuz his bf didn't give him any. I think he's the gay b***h, b/c not only is he gay, but he's the b***h in the relationship.

I got one for him since he knows 99% of the answers. I gotta buddy that's got a 93 RX-7 TT, he needs help findin some pistons, rods and rings for it, any suggestions on where to start lookin? Parts stores, internet sites, anything?

And for the record, I know what engine the RX-7 has in it. Plz don't flame me for that, but if you must, you must. But be prepared.............

For the yard gnomes will come and visit you!!!!!
