My R33 Rb25det Won't Start And Its Not Cooler Pipe.

[vladr33]

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

have you checked the base timing. maybe you've jumped a tooth on the timing belt

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.
