I have a 1996 Chevy express conversion van with a 305. I just replaced the engine with a crate engine but now I’m not getting spark. I have checked all the grounds... replaced the distributor... the coil... the crank sensor.... and tried a new ignition module. I’m at a loss for what to try now. Any suggestions?

 

Welcome from Florida. Did you check your fuses and wiring to see if by accident something was left unplugged.? Never overlook the obvious.
