1997 Chevrolet K1500 5.7 random stall was created by spencermartin89
I have a 1997 Chevrolet Silverado K1500 5.7 MPI. It is randomly stalling. No rhyme or reason. Fuel pressure is not dropping out at all. I’m losing spark. It is random and inconsistent when it stalls. Before it was brought to me the owner replaced the PCM, plugs, wires, distributor, cap and rotor, fuel pump, starter, fuel filter, and ignition coil. They couldn’t get it to run at all. I replaced the spider injection and got it running but it’s losing spark now. I have not been able to pinpoint whether I’m losing control from the ICM to the coil, or if my crank sensor is dropping out. Has anyone seen anything similar? Thanks in advance
