vehicle won't start on 1993 Ford Explorer
This is a prime example of what should not be done. Do not throw parts at a prob like this. The fuel pump will not fix spark and the computer is typically not a problem. You need to have a qualified shop look at what can cause both of these probs at same time like a constant control relay module.
Perhaps a PCM power relay? Hmm. Unusual situation.
Very rare for one of these trucks to have a bad PCM but I have seen the relay go bad. We would gladly check it for you if you would like to make an appointment at 770-945-1399.
