I have a 1999 truck that i got with a bad 2000 engine in the back. I rebuilt the engine and trans and installed them into the truck. The ECM, wiring harness, and engine are all from the 2000, and match with each other.
The problem I am having is the engine will not fire. After bleeding the injectors out, it fired a few times till the starter was disengaged, then it would die. Since then, it wont even try to fire on fuel. It will fire on ether, but that is it. Just barely puffs out the exhaust.
So far, I have eliminated the cam sensor, ECM, injection pump, injectors, confirmed gear and valve timing, confirmed valve lash and put brand new fuel in it. Lift pump is a new Raptor block mount style, tried cranking with lift unplugged in case it was over pressuring. Getting fuel to cross tubes.
Did a compression test on #1 cylinder 3 times with different results each time: 50psi, 100psi, 75 psi. Comp. tested #2 cylinder once, got 75psi. Switched to a leak down test on #2 and could hear the air going into the crank case, but I'm fairly positive the rings haven't seated yet, so not sure if that is accurate.
If anyone has any ideas I am absolutely all ears. Willing to try just about anything at this point.
