I think I have it down to compression issues now. After ecm, fuel, spark, prom, :mad2:...are working atleast for now. Its came close to
becoming a combustion issue solver!!!:rolleyes5::hihi:
Back ground: I have a 93 c2500 5.7, nv4500 spun a main.
the motor Im asking about, I cranked and ran, in a 93 gmc k3500 5.7, auto. Bought the truck, pulled motor. Put new timing chain, oil pump, new gaskets except heads. Its whooped me for the past month since then. I think I have all that taken care now but still couldnt get it crank. If i dont turn it over for a couple hrs, 1st time as long as i got the remote pressed, or key turned its so close. Almost there, its like it just needs a lil uummfth or something and would fire right up. It kind bubbles out the tail pipes, not pop or back fire. has full battery. then release the remote for a second or an hr it doeas nothing but turn over like theres no spark, but it does have it. So i did a compression check dry & wet.
