i still haven't heard how you confirmed the injectors are fireing. you should do that before you tear the motor out.

one way that will tell you something is let the fuel pump prime up to 5x. psi. presure should hold with the key off. then pull the fuel pump fuse and crank it over. the presure should drop if the injectors are opening. if the presure stays the same then the injectors are not opening.

are the plugs damp at all or dry? do they smell like fuel?

LOL no extra pushrods. We confirmed fuel 2 ways: one we pulled the plugs and got fuel pushed out of the plug hole on the compression stroke, the other way we just pulled the rails with the plugs attached and let them fire. LOL lets just say they have a very nice atomized spray. Eau de gasoline anybody

Went over all the sensors to make sure everything was tightly plugged in - they are. That was the first thing we did. Then we checked all the grounds - they are still all good.

My brother actually said bent pushrods when I first called him. I just refused to believe him. Maybe tomorrow I'll have some new news.

When you put in the new PCM, did you do a CASE LEARN, adjustment for the crankcase sensor. While I have not heard of one not starting, you might check for the P1336 code.

when you are trying to crank it with your tuner are you seeing atleast 750 rpm if not you might have a bad crank sensor or cam sensor.

Bizzare....you'd think it would've at least sputtered a little with the old ones.
