Your plugs are dripping fuel? Are you using an upgraded fuel pump with a stock fpr? If you are then your pump is over running your regulator. If your using a aftermarket fpr then disregard.

regardless if it were an aftermarket pump or not, it wouldn't overrun the stock FPR to a point to cause a no start situation.

is factory fuel pum and fpr. i didnt want tostart up grading parts until car was running in a better condition, but then this starting issue came about. i was reading online that if this resistor doesnt work the fuel injectors dont pulse they just run wide open all the time. so i'm def. looking more into this.

step 1: go to http://www.ebay.com

step 2: search for DSM dropping resistor

step 3: buy it now

step 4: wait for arrival

step 5: install DSM dropping resistor

step 6: confirm diagnosis

you can get them for around $20 shipped or if you have access to them locally just do that and see if it works. if not, you have a spare dropping resistor. I understand you dont just want to throw parts at it, but sometimes, you have to.

I didn't think it would be the main problem. I just am wondering if it was contributing to it running rough before. I know it would start but I noticed she mentioned something that made it seem like maybe the fpr was being overrun and I thought I would just check to see if that was the case.

Edit: Just read that you have a stocker so no worries.

i dunno, i just know i'm getting dumped in fuel and to much fuel will cause it not to start. b/c u have to have oxy for it to actually ignite.

if your resistor wasnt working......... you wouldnt be fouling plugs........ your injectors wouldnt even be firing.

Hmmm idk then. I'm just going by what I'm reading online. What's with the long .....? Any suggestions to the fuel soaked plugs , all 4?

it is within your ignition, vac or timing.

either your ignitor is weak, coils are weak, huge vac leak or your timing is off......

I had the worst time w/ getting timing down. the car would only idle if I had my brake booster unplugged...... just a matter of being out of timing just the littlest amount.

I must say I would pull the MAFS and unplug it........ It will help rule out vac issues atleast. the car will dump fuel and idle rough, but it will atleast idle and rev up to 2k. Then you know you are having vac or SAFC issues.

Some people have real issues with their SAFC, and if it was set based on a bad timing belt........... it is possibly it needs to be re-calibrated to "proper" timing.

these motors arent that advanced, so it doesnt take alot of thinking to figure them out. Just takes some paitents and small hands.

I've pulled all four plugs out they r firing. Timing belt is set properly I've checked an rechecked. Car was fing up before the belt change. I changed it because I thought it might have been the issue with it not starting. It was driving one day I parked it. The next mornin went to start it and it starts then shuts off... please read all previous posts before making statments.

If it was a huge vac leak would the car really have run one day and not the next. Why would there be fuel soaked plugs? Ecu throws no codes. All vac lines are brand new and were mapped out according to nissan. And the car ran before just like s*** because it was so rich. I have already un pluged the maf and there was no change same with tps.

Ive read all your previous posts. if you think you know better than everyone else trying to help, that is fine....... gl to you.

Ive only been around 3+ years now(not like ryan, dee, tim, ect), and in my short time.... timing is 98% of the issues.

the other 2 percent:

bad MAFS- wiring or the sensor itselfbad CTSstupid 1/2 as builds(surrounding poor wiring and/or ghetto rigging)

at least with my S13, I had to take apart several components to change the timing belt.......... maybe this isnt the case for you idk. If it is, it is very possibly you forgot to hook one little thing up(it happens).

If you had issues before, but it would start up, there are a number of threads on how to sort out pig richness. that also means that ONLY ONE THING HAS CHANGED! can you guess what that is, and why people keep echoing the same reason you are having issues?

Failed ignition=fuel sprayed w/o igniting= wet plugs...... pretty simple

If I thought I knew better I wouldn't be here asking for help. And wouldn't thank people on here like I have been. And this car was soome one elses half as s job that I'm trying to fix. Just everyone saying timing. Because I mentioned changing time timing belt. I checked and rechecked and rechecked my timing. I even had some one else look at it today... there was a lot of wiring done before I got the car. So who knows what's wrong.. my luck its a stupid ground loose.. cause the cars not even starting now. Where is before it would start n shut right off.. now its just rotating.. and he says my timing is fine. And I was never once rude to u btw. I said please... its just frustrating on here when people make statements with out looking. Timing was ruled out because. 500 times of checking later its set right.. and the problems sown up before the change. It was never out of time to begin with. The car ran rich but it atleast it ran. So when things failed I ask for opinions.. urs is timing... ok thank u. Other then timing guys any other ideas?

According to its original marks yes. And original marks was nissan set timing. I played with it to see if moving it made any difference in the car.. but moved it back when I still wasn't getting a start up. Ill know tomorrow what's up with it. This guy came highly recomended and is older then the flintstones but he knew the mechanical make up for this motor. He says that kids always mess up the wiring. So once he calls me tomorrow ill post up what was up. Thanks guys for at least trying to help its hard to go by other peoples description of car problems... with out actually seeing the issue its hard to tell what it really is. I'm going to bed night all.

ECU not plugged in all the way, broken exhaust cam pin going into the CAS, bad or loose ignitor chip, bad or loose injector dropping resistor, blown out FPR, etc.

ISSUE WAS NO INJECTOR PULSE! Lol now we just gotta figure out why. Resistor works but the guys are checking the reject's wiring hack job that was on here. People half a** wiring jobs to be cheap. Sucks. but I'm happy the problem wass found !

To be honest I'm not sure how this worked out the way it did. I was getting 12volts to the injectors but the were pulsating. its like they were just stuck open. I checked the resistor b.c th idiots I took it to said that was it. But when I got a second opinion other then my testing. It checked out fine. The problem is withing the wiring. I noticed my relay isn't clicking but they relay is good. Tested harness and low and behold issue is there.. this wiring f-up is due to cheap people before me.I cracked open the wire harness rolled all in elect. Tape... yeahhhh no proper connections just taped together... so now I'm currently reworking wiring. Thank u guys for all ur help. If u have any links to the wiring to the fuse /relay box in engine bay please let me know.....I'm not great with electrical but I'm not completely lost on it..

Your car sounds like mine lol good luck on the wiring. I had to send mine out to Yury at wiring specialties and he worked magic. Also I didnt know there was another CA in Charleston

dont say it like you and her have the only CAs here fool. I don't, just saying...but i do have a boosted 240. Being that I work with Kaforlife, I'm always asking for updates about his car/working on it with him. Now I someone new to nag about seeing how things are going with their car (thatjdmchic).

I need an o scope... imy wiring is messy so I'm sorting threw it. I got voltage coming in and out the ecu but its hard to read the injectors vlt. Because it pulsates. Stressfull but gonna work it out.I'm new to the area here But I go out to the little car meet up off rivers. By the kmarts on sat
