Need help! RB25DET Major Problem! I'm stumped =[

[Michaelove]

To start off, it's an RB25DET with a bigger t3/t4 turbo, z32 MAF, power FC, and lots more.

Okay i'll start from before things screwed up.

I had fixed all the major problems. I siliconed the coil packs and they stopped arcing. My car was running great. I was still on the stock ECU until about 2 days ago when my Power FC finally came in. I put that in 2 days ago and the car was running even better, just really rich. I had been driving it around, being really careful to not get on it because the Power FC was not tuned yet and still has not been tuned.

Anyway, I drive my car to my girlfriends house last night, the car is running great. I slept there, wake up in the morning and go home, the car was still running great. I thought i might have had a small vacuum leak so I got some starter fluid and sprayed it around the intake manifold. Around the injectors sort of, all around there. I hardly sprayed any. I turned my car off and turned it back on a little bit after and while it was idling I was looking through my commander for my Power FC, through the injector part of it. A little later I noticed that my car was idling funny, like it was missing a lot. So I gave it some gas and almost nothing changed. It started popping and running really really bad and it could hardly hold it's idle. I could not get the car past 1500 RPM even if I gave it full throttle. It was running SUPER rich.

So I got out of the car and pulled each coil pack wire off one by one to see which cylinders were missing and what not. I pulled the first 5 out and nothing changed when I pulled any of them out.

I then decided to reset the Power FC ECU to see if I messed something up with Power FC for it to be doing this. I reset it, let it learn and all that. I let it idle for 30 minutes. I came back out, reved it up, and the exact same thing happened. Nothing changed at all.

I then decided to put my old RB25 ECU back in and that made things a little better. I could rev it to redline in idle and it was holding it's idle fine but it was still missing. So I tried disconnecting coil packs again and I found that the number 1 coil pack did nothing when I unplugged it, but the others did change something, the idle dropped everytime I pulled those out so I knew they were fine. So I went to swap the coil packs from cylinder 1 to 2 and 2 to 1 to see if it was the coil pack that was bad. I got in my car to start it up and.....it just turned over and turned over and turned over. I can't even get it to start now. I tried plugging power FC back in and it wouldn't start with that either. So I figured that I was flooded and gave it a bit before I tried cranking again but it still didn't start up. So I had a friend hold the coil pack next to the block but it didn't arc out so I don't think i'm getting spark now.

I'm letting the car sit over night to see if it was flooded or what.

What could be wrong!? Any ideas or help will be greatly appriciated! Thanks in advance

Sounds like you could have at least one bad coil pack. As far as the other wackiness, I'm not sure. I've had that happen before with PFC's and that's why I'm not a fan of them "learning" stuff.

Did you change the MAF setting on the PFC to a Z32 MAF? And did you disable the boost controller kit before starting the PFC up and letting it run through the idle learning process? The default is for it to look for the boost controller kit.

When you do the idle learn process, it is critical to turn the car off so it completes the learning cycle. If you let it idle for 20 minutes and then take off and start driving it, the idle and off-throttle will be low and the engine will bog. I know because I've forgotten that step a couple times...
