1993 Chevy Lumina 6 cyl Front Wheel Drive Automatic

93 lumina 3.1 california car:
what could cause the signal to the fuel injectors to cut out?
it will start sometimes, others not. when it wont run the fuel injectors dont fire but it has spark n fuel pressure.
also at times it wants to fight turning over as if the timing were off causing it to fire at the wrong time.

A pcm, a connection problem at the connector or in the wiring can cause an injector failure as well as they can plug and the can have a voltage change. Use a noid light to see if the voltage is wrong.

3.1 motors did have plugging issues that were sometimes able to be cleaned.
