Lincoln Repair Questions? Ask a Mechanic for Answers ASAP
Hello, my name is***** and thanks for your question.
So you checked fuel pressure at the time of the no start and it is good?
Ok thanks. At this point it sounds like it is still a fuel issue. Ford fuel pumps never fail once they are running, they always fail from the off position. Since it is intermittent and heat related I would have the PCM and fuel pump relays replaced. They are inexpensive and known to fail for this symptom.
Here is the relay locations in the underhood fusebox in case you want to replace them yourself.
That would be great if that's all it was.
Best of luck!
Sorry to here that. I guess we need to figure out if it is loosing fuel pressure or if the PCM is going off line. Do you know if any codes are returning?
