This model doesn't have a cam sensor. It could very well be the crank sensor, but she doesn't stall, doesn't shut off during acceleration and doesn't backfire. I've got good spark and good injection pulse.
I think that I have pinpointed down to some bad connection dealing with the fuel pump.
Originally, I bought a new relay for the fuel pump, but I was having the same starting problem, so I took the relay back to the store and replaced the pump, think that was the problem. The ranger ran fine for a week before the problem returned. When it happened, I replaced the coils, with no luck. I also pulled the ignition control module. Even though my old one tested bad, when I put in the new one, it didn't resolve the problem. The frustrating part is that it happens infrequently. The one time that I noticed a problem was when it was either hot outside, or the engine was hot.
Besides the relay and wire connections, is there anything else I can test? Could it be the ignition switch?
Thanks for your help.
