hey guys just wondering if someone could help me out. i've got a r33 with s2 rb25det, 6boost, big garrett and making 400hp but on sunday i got up, started it was running good, then drove to the track for powercruise (wa) and was waiting in line on idle and it decided it had pro cams in it and startd idling lumpy then when i went to take off it stalled n from then on i couldn't get it started agen....... see my problem lol.

i checkd it yesterday and pulled out no.1 plug and it was dry after tryna turn it over few time and made sure it was geting spark witch it was and checked the other ones and they were wet but not dripping... but all getting spark and battery is allil dead but we had jumper leads on but still wouldnt start just turns over.... any ideas would be much apprecaited. cheers

As much as it pained me to read that short paragraph..

Ok so your either missing spark or fuel, the fact that your 2-5 plugs are still wet sort of tells you it's probably missing spark still, despite you saying it was checked. How exactly did you go about checking spark? Have you verified fuel pressure still?

Rip the feed line off the rail and check it primes with ign. I was going to recommend putting the ECU into diags to check for fault codes, but looking at the mods it's probably not running stock management anymore.

As often as it's said for it to die completely like that I would be leaning towards a faulty CAS at this stage, thats pending your answer on how spark was verified.

hey man, yeah we checked the fuel by like you sed pulling it off and turning ignition and it had fuel. we tested spark by pulling out the coil and plug and sitting it up and turning it over and it was making spark so im kinda thinking cas sensor to... but thanks for all ya feed back. so what you reackon? if it helps was in powercruise the day before giving it abit and then burnout comp that nyt.. but started fine in the mornong.. lol cheers ya help

Im assuming u have an AEM computer? a PFC or something ?

I had the same issue, fkn lumpy idle, guttless, and died. My loom was loose in my pfc ecu. Tightened up the screw and she was sweet.

    • Interesting.  Great info. thank you.  Give a few days to get that name plate.  I have a busy life most weeks.  I will be in touch.
    • Strange your posting about this being an issue. Move the harness or change your wheels or run more camber etc. Have the thing not touch the thing so it doesn't destroy the thing.  Short answer, no. Slightly longer answer, the factory fuel gauge is measuring resistance. You need to wire in the FPG fuel level sender into the original factory fuel level sender wiring.  I drew you a picture to explain this one The factory strainer is quite long, reaching down into the bottom of the tank. Safe bet your aftermarket fuel pump has a little baby sized strainer that probably doesn't even point down towards the bottom of the thank.  Solution, move the pump lower down in the tank, or fit a longer strainer, or do both. I did both, I've run my tank down to 5L remaining and the car still drove fine.   
    • S2/3 GT-R is the same as S2 GTS-t The SRS airbags module in under the centre console. The S1/S1.5 GTS-t and S1 GT-R had the module built into the steering wheel. FWIW, I have a S3 GT-R wheel in my S2 GTS-t shit box. Same airbag plug, airbag light goes on then off, meaning all systems are go. S3 GT-R has red stitching, that's about it.
    • Dumb question, but why would it matter if the wheel came off a car with hicas or not?
    • Hey to anyone that reads this, long time lurker first time posting, sorry if it’s been answered before but I’ve been looking for nearly a year now for answers. ive got a 25det neo in an r32 that works awesome when it works (made 500whp on 21psi) but works 45% of the time, 1st issue there’s a harness that runs under the passengers side front fender that my tire keeps rubbing through and one wire seems to power the fuel pump even though I’ve done the relay “mod” some people like to call it, and when it does rub through it kills the car, yes next time I’m with the car I want to take the fender off and try tuck the harness well out of the way but I’d also like to try and by pass this mysterious wire as well lol, also wouldn’t mind getting power from the alternator as I’ve read it supplies the pump with 13v ? But no idea where to run the power wire too. 2nd issue, when replacing my fuel pump and fuel hanger I managed to break the factory fuel level sender leaving me with no fuel gauge, I’d like to buy the fpg fuel level sender for r32/s13 but the plug it comes with confuses me, I’ve got a detschwerks x1 fuel hanger which has light + pump - level + pump + and a ground, I’m no auto sparky but I’m wondering if I can cut the plug off the fuel level sender and wire the negative to the pump negative and wire the positive to the level positive to get a fuel gauge back ?🥴 3rd and final issue, the reason I want a fuel gauge is because whenever it’s below half a tank, it fuel starves like crazy and runs like a bag of shit even without doing a pull or sloshing the fuel round in the tank, I’d also like to fix this but have no idea what’s causing it, I’ve got a dw420 and a dead head fuel setup meaning the fuel is regulated before it gets to the engine, my only theory is that the return line is to close to the pickup on the pump and when it’s at half a tank the return line is causing the pump to cavitate enough to cause fuel pressure issues, that or the pump isn’t low enough in the tank which I would find strange considering I can’t find a single thing online about it, also if ya wondering how I figured out it happens at half a tank without a fuel gauge, I waited until it started happening and went and filled up and the car took exactly 30 litres every time I tested it, if ya managed to read through this mess I appreciate that and any recommendations , cheers
