2000 c3500 5.7 vortec.
All items replaced so far are gm genuine or delco.
ICM, coil, cap, rotor, fuel pressure regulator, oil sending unit (one wire type), crank position sensor, temp sens
Truck came with updated injectors.
Code reader says cannot connect to ecu, but has power. So is there a chance for computer to be bad?
Problem: after running engine up to temp then letting sit for at least an hour and up to about 4 hours, engine cranks for up to 8 seconds, has lousy start, then dies. P1351 pops up and I have a handful of delco ICMs now.
If I hold the gas pedal to the floor, the truck will start and not die, so I’m suspecting something to do with flooding.
I’m ready to buy a pre flashed computer, I don’t know what to do from here.
