had 1995 gmc truck under water. replaced computer, disributor, fuel pump assembly.
i had no compression, so i swapped the block and heads from a 1992 chevrolet. it had a 4 brl carb and intake, but i kept my throttle body and intake... i have good fuel spray and clean fuel, i have fire at all plugs  ( used a spark checker ), and with engine at tdc on #1, the rotor button faces the #1 plug on compression stroke. will not start.

it started a couple of times but i had done something really stupid i had the engine block grounded, but not the neg side of battery. then engine block ground burned in to, so i replaced it with 6 gauge wire. since the ground burned, it turns over and almost cranks, but wont... Please help!

Have 150 psi on cylinders now...

have you checked all the fuses and connections? when it cranks over is it fast or slow
