Dude, I told you that you might have collapsed the AFPR when we were there. I knew it. The second your car goes into boost, it instantly turns all vacuum systems into pressurized systems. In regard to your IM, I don't have my stocker, but I can get one cheap through Norm.
Well it's not the FPR, I put a stock one back in and it's still messed up, still don't have pressure. My father said to pinch the return line and the pressure should shoot up, if not then it's something in the tank, it didn't shoot up when I pinched it. It actually stayed the same. So i'm about to drop a 1/2 full tank by myself because this whole problem is REALLY pissing me off. And this is my daily driven car
It's a new fuel pump and sounds fine when I prime it, the FP also just drops right off when I shut the engine off. It should stay pressureized for a little while after shut down, but nope....I thought it was the FPR but had a feeling I would continue to chase the problem.... at least I'm making some progress
The feed line from the pump came off somehow put it back on, and tightened it up, and the car pulls so hard now. When i tested the TFI module i put the timing to 11-12* and i think thats where some of the power is coming from. It's great now!!
