My friend's 1994 Ford Ranger doesn't start sometimes when it's warm.
After driving for any amount of time, the engine will turn, but it
never starts. It will eventually start once the engine cools down.
She has had no problems at all with cold starts. The warm start is
only intermittent, though.
Mechanics have shown their lack of experience by blowing hundreds of
dollars in repairs that have solved nothing. They're helpless because
it never fails by the time a mechanic gets involved.
I already have a solution in mind, but I am looking here for
additional insights from your collective experiences.
I plan on replacing the coolant temperature sensor. This sensor could
be giving the fuel injector a cold start condition when the engine is
actually warm. That would cause the fuel mixture to be wrong, and
subsequently the engine won't start.
Does anyone have any other ideas?
Thank you so much for your input.
