Hey all, I'm having a problem after my build. Last fall my clutch went out, so I decided to drop the cradle and do some work. I did 2.7 pulley, 60 pounders, zzp tuned PCM, water meth, ported head, and intake. After putting it all together now the car won't fire. I sent the PCM back to zzp to get reflashed, and no change. It's got spark, it's got fuel, just doesn't seem like at the right time. The cars been at the dealer since April and even they can't figure it out. So maybe someone here has had the same problem. Seem like a cam angle sensor problem?maybe I didn't line it up right on install? Maybe it went bad? I also put in my gms2 to see if it was a bad PCM core from zzp and it did the same thing. I'm out of ideas and so is the dealer. Any help or suggestions would be appreciated!!

 

Sounds like a timeing issue to me.

 

The dealer has checked valve timing 3 times and it's good

 

do a compresion test

 

I think maybe Its that sensor, we had issues with it when we put back together a guys lsj, the car would start but stall right away his wasnt far off though.

 

I did a compression test. 140 dry all the way around. Im thinking of just throwing in a new cam sensor for piece of mind and see what happens

 

Don't you have to do a case relearn

 

well this is what i would i would check for pinched wires from were you pulled out the transmission and put it back in then once you got the car running i would put a set of rings in it 140 is way low
