I don't have any spark from the distributor. Computer, coil, ignition module, have all been replaced. I have spark going into the distributor but none coming out. The truck is a 88 1 ton with a 454. I have also replaced the injectors, fuel pump relay and I have 45 lbs of fuel pressure. When turning over there is no fuel going in but I understand that is because there is no spark. Please give me any suggestions to check I am really puzzled. Thanks

 

If you have good spark out off coil and into dis the you need a cap and rotor

 

Thanks I'm going to try that this morning, I was also thinking maybe the pickup coil.

 

Pick up coil sends the spark signal to the ignition coil. If you have correct spark out of ignition coil the pick up coil is work.
