Hiya all. I got this thing a couple weeks ago with a buddy. I need to get her running since i am leaving for the air force soon and can't very well take her with me. Gotta find a nice and loving home for her, and get some of my money back:)

1991 s13 hatchback, with an SR20det redtop.

performance Mods are fmic, piping, K&N cone filter, HKS SSQS, and... it now jas a brand new walboro fuel pump. Not bragging, just informing in case something is causing it, er something, idunno

So about two weeks ago, the car started developing a boost leak between the manifold and turbo. This might be unrelated but it cause the car to run rich, loss of boost and loss of power. This might have nothing to do with it, but it still happened.

Couple days later the car wont start, it's not getting fuel. It gets spark and turns, but no fuel.

We figured it's probably about time for a new pump anways and drop in another walboro 255LPH

Now there is still nothing. Possibilities that people have said areThe security system might be tied into fuel?Someone said it might be something called an inertia? Switch? We had the car jacked up pretty high on one side to raise it up to get the other side up and... well it was really high up. Someone said that might have triggered it. I just found out where the pump relay is and I will be checking that in a little bit.

Any ideas out there? PLEASE. I am begging you!

Unless someone spliced in an aftermarket security system, there should be no such thing on your car. If there is an aftermarket one, you're going to need to know the make/model and try to obtain a wiring diagram of the system.

When I lose fuel pressure, I start to look at possible culprits. You eliminated the pump, but make sure the pump is actually turning on. It could be a bad wiring job for the fuel pump on the SR harness, or it could be a bad fuel pump relay (labeled EGR Pump Relay IIRC). You can use a test light to test that the relay socket is getting proper power (in effect testing the continuity between the ECU and relay box), and you can test the plug in the trunk to verify if the relay or wiring is working properly.

After all that, you should look at the FPR. Sometimes when they go bad, they stick open and you lose pressure. Get a fuel pressure gauge to verify what the pressure is and make a determination there.

As for the car being tilted, unless you had less than a 1/4 tank and had it sitting at a pretty severe angle, you should be fine on the tank front. There's baffles to keep fuel near the pickup.

Lastly, congratulations on joining the Air Force. I myself am waiting my class date to be assigned for basic. I'll be doing 13B (Air Battle Management).

Thanks for the help last night, it got to about 34 degrees out by midnight so I had to button her up:( I work in a cold warehouse, then come home and went straight outside to a cold car and worked in the cold dark.... I just wanted to feel my fingers and toes again, knowhatimean?

Changed the fuel pump relay, and the ignition coil relay as well since the plastic see through top popped off when I nudged it, so I figure it was time!

Nothing happened....

I disconnected the fuel pump and tried to start the car(curiosity and all) and it actually started to turn on its own volition! Don't ask me why it just did. but would never actually go. Just more than it had since it died So I checked a couple connectors and got nowhere.

I then decided to test the electricity coming into the relay switch..... but I know nothing about electric testers. The only reason I remembered how to read the relay was because I just studied hella hard for the asvab.

I plugged the probes into 1 and 2, then 3 and 5, and just keep switching them until I got some sort of a reading.. ha. So the other guy that owns the car with me though, lets try starting it to read the relay, thinking that it would not turn on anyways. We did with the probes in 1 and 3.

IT TURNED ON!!!!! The car turned over and stayed running, sluggish but running, for about 10 sec! VICTORY...Ish. I plugged the probes into 3 and 5 and it started again and died. Then I just took the probes out and had no relay in and it started again. I took the relay to the left out and it still started. The car was starting with out the relays.

It ran extremely sluggish and would die out after a couple of seconds, and if we gave it gas it would just know or ping pretty bad and die. No hesitation to stay alive, just die. I am thinking a compression test is in order tonight, but I have to get it running for a couple reasons most of all so I can move it! Since my landlord wont allow more 3 cars, and this is the fourth Wow, I have never used those stupid smilies, but they seem to come in handy when there are so many of them!

The major accomplishment of the night is that now IT NOW SMELLS LIKE GAS IN THE ENGINE BAY! (there is a slight exhaust leak from manifold to turbo) so that means the gas is getting there!

Now all we have to do is figure out how to get it to stay on, then, with some help, DRIVE!

Thanks for everyone's response in advance

BTW I have no idea what I am doing in the Air force, they have not assigned me, but they said they will be putting me into the mechanics pathway. Don't know why but I don't plan on fighting it since it's something I love and they will pay me to learn more about it! But instead of the 6 months they are giving me about 2 due to my asvab score. They actually called me yesterday to see if i wanted to leave tonight! Said no just because of the holidays and my daughters birthday. Flip side is that

If you're having pinging issues, check the timing to make sure it's in time. An out of time car could also cause your no-start issue.

Given that it has fired with the relay completely pulled out of the loop suggests you might also be seeing an over-rich condition. With the pump turned off, it means the car is blowing out gas that has built up and pooled up. Being out of time could also just be wasting the gas that's being pumped in.

I'm jealous that at least you were asked to leave immediately. I'm going officer, and BOT is annoying about how it fills its basic classes. The January class is already full and I'm worried that AETC is dragging its feet enough that the March class will be filled before I can get assigned and I'll have to wait till April.

How am I supposed to time it when I cant get it steady?

How do I adjust the fuel to air ratio on the SR20? You guys are life savers!!!

I am gonna try and go officer once I get the bachelors the air force provides, I want to be a pilot. They said that my depth perception is horrible, I am convinced that they fudged it due to my score just to get me in. I told them "say that to the people that have gone 170MPH with me and see what they say....." Good luck to you too! I am thoroughly supprised at how many people on the forums are military or going for it. I know a LOT of cops in my area that have the same swap.... so they leave us alone

You can set the time without the car running. Hook up the light and have someone crank the car. You'll still get a pulse off the timing light even if the car isn't running.

As for adjusting A/F ratio, you'll need an adjustable FPR. I recommend NISMO units. However, I wouldn't just throw a part on there unless you are certain that your stock FPR is bad.

As for the depth perception, I scored a 7/10 on my flight physical test. I hate the depth perception tests with all my heart as they don't work right with people with glasses. The secret is to cross your eyes and let them focus like you would for one of those 3D puzzles. If you fail the DMV style of test, they'll let you take one that is projected on the wall and give you special glasses to see with.

I guess the next questions is how do I know that the FPR is bad?

I just called a shop and they were kind enough to tell me there professional opinion is that the MAF is bad. Any ideas on that? I read a couple good ways to test it is to take it out and clean it, tap it and unplug it and see what the car does in response. ? Thanks

do not tap it with anything... You can pull it and look at it -- if it is black or dark and you see no other silver or anything on it then go and buy some MAF cleaner which is like 5 bucks a can but it will clean it right up. Have been around Nissan's a lot and a dirty maf will cause it to miss a little and run a little rougher -- it really will not put out the symptoms you are talking about.

Normally a bad MAF on this era of Nissan will cause the car to default to limp mode. You'll get a rough idle and it won't rev over 2500 RPMs

As for testing for a bad FPR, you need a fuel pressure gauge. If it isn't reading 43 psi on the line, the FPR is either stuck open or stuck closed. I usually see them fail open, but it wouldn't surprise me if a vacuum leak was causing this, or if the FPR just failed shut and was giving you an over-rich situation. You won't know the situation of the FPR until you hook a fuel gauge up to the line.

If this issue falls down to a wiring gremlin, you're gonna have to buck up and start doing some digging yourself. The problem with wiring issues is that not everyone's wiring problems are the same. A broken wire, or a mis-soldered wire are in different places on each harness because nobody wires the same. It's the issue you deal with when you have custom wiring done up.

From the sounds of it, I don't think it's a wiring problem as the car has ran, albeit roughly, briefly. And it did it when you pulled the pump relay. Next time you try to crank the car, pull a spark plug out and give it a sniff test. Make sure it's not fouled with soot or completely coated in gas. If it's the latter, you can pull the plugs and let the cylinders air out. If it's the former, you should change plugs.

Also, don't rule out bad gas. I don't know how long this car has been sitting, but if it's been a really time, the gas could just be bad. Especially if it's still low-octane. I've seen quite a few issues with non-starts solved by putting fresh gas in the tank (after you siphon the old gas out of course)

Gotta post the car. Leaving soon and can't keep a toy thats not a toy....

On Ebay, here is the add.

Reserve is set at $2,700,

FREE DELIVER WITHIN 100 MILES OF VEHICLE LOCATION

Car is also for sale locally, and there are many interested parties. If you would like to make an offer to end auction early, do it before someone else does!

Everyone knows these things are awesome, but I never knew how awesome they really were until I had one with this engine!

My buddy and I got it and we've been loving it ever since. We took turns daily driving it.

We bought it as a toy, and so my buddy could have something to drive until he fixed his own car. His car is fixed, and I am getting deployed soon, so the car has to go since he can't afford to buy me out of my half so it has to go to another loving home

The goodsS13 hatchback with a redtop sr20det3" downpipe3" exhaust to magnaflow loudHKS SSQS blow off valve with a nice clean pshhhhht sound. How I love those BOV'sGodspeed Front mount intercooler Nice and big, just so everyone else knows what your running with:)Megan CoiloversShort ShifterK&N style dual vortex? cone filterChargespeed body piecesuhhhh, racing wheel and light blue racing seats

The car gets up and goes! It's fast as Apollos Chariot itself-ish. We haven't started trying to drift it but I am nothingbut positive it will slide that back end out like no ones business! That was our plan, but I can't even get an hour to go play some pool, let alone a weekend to get outta here. Knowhatimean? With those Megan coilovers its life should be nothing but drifting. As much as it pains me to say this, were no drifters. We posses the skills, but I have a family and I'm shipping out to the air force soon, and my buddy has a business and goes to school full time (kaislist.net is the best, check it out if your in college)

There are the reasons were selling the car. It runs decent, its a BLAST to drive and with that exhaust, that turbo probably spools full at 2,500 or so? it is one badass ride!

Here are the things that should get addressedThe front bumper is not on the car right now, we took it off when we were inspecting the intercooler setup (nothing wrong, a ounce of prevention is worth a pound of cure). Car could use a radiator support, WHICH IS INCLUDED! Doesn't need it, but would make some things a lot easier. Cars engine bay is pictured, and not perfect, but all there from what we know. Body is not pretty, but hey, it ain't a civic either! The Charge Speed side skirt is torn on the drivers side, clean straight and is entirely fixable. If you have a little knowhow with body. Or it should be a $25 fix if you were to take it to a body shop off the car. There are dents and dings, scratches and what not. Dirty too, could use a bath. Also there are random bolts missing in some parts, but were replacing them more every day. I am not sure if it is authentic or replica, but I can tell you the sides and rear bumper are (see emblem). Dent in the roof. Probably an easy pull Car has a decent ride, but coilovers need to be dialed in a bit better. Mechanically, we drove the car on 6-7 hour trips multiple times. Lots of fun, but we never got a chance to drift or drag it. We never even took it up past 6k!. The things it needs: Oil pan leaks. Not bad, it leaks as much as my E39 540i burns, ha. Have to make one since I can't find one anywhere ($10 at kragens).Car needs timing, and it has an exhaust leak somewhere, but from what I know, that just means louder:) Sputters and smells like gas in the engine bay, which is due to the Exhaust leak, and it ran pretty rich. The engine turns, and there is spark but something with the fuel. so please understand this. Car has a brand new walbro 255LPH. Any offers of more than $2,500 with be considered, with parts taken off to reflect the offer. car has this's and that's wrong, and were not even sure if we have found all the good and the bad yet. I am not responsible for stuff I don't know, but I have said everything I can. I know what I know, and that's all I know:)

I hope I have disclosed all I know,

For sale as well is the following

R32 rear end VLSD (car already has LSD, we just happened to acquire this)Extra Set of rims with tiresAn ENTIRE Skyline r33 Front end(radiator support, crystal headlights, gts-t type m? bumper, fenders and hood, hood needs work) I chose this because I though it would look WAY cleaner that the GTR fronta couple other goodies here and there, box of them to be exact, we'll probably throw it in with the carParts don't come with the car but might be willing to include them for a very good price, or if the auction gets over $3,300If I didn't have a over full time job and a family, you probably couldn't pull me off that car and I would spend all my money going to thunder hill:)
