Help With 90" Chevy 1/2 Pickup 305 V8
The motor will turn over but will not start.
There is no spark coming to the plugs,The injectors are not supplying any fuel though there is fuel coming to the throttle body. The fuel pump is working, you can hear it with the gas cap removed.
I had auto zone check the ignition module (it tested good), I bought a new coil it didn't help.
someone said it may be the computer, for some reason the spark and fuel are connected and both not working.

I would think if the PCM had a problem, it would throw a code, or 2. Unless, the PCM is dead and can not lift it's head to throw a code.
Give us some background..........for example, worked fine when I drove it home, next morning it would not start.
Also, you changed the coil, what else have you done to try and fix the problem?Ray
