& I am helping a friend over 1000 miles away over the phone. And I am looking for an answer to the question of "has anyone else had this SAME problem"?
he has a 91 super coupe that he has been stabbing in the dark for 2 weeks now, NOW he calls me!
ANYWAY, the symptoms are that if he lets it sit and run it will run fine forever.
when he drives it 10-20 minutes though it will begin to fluctuate on the temp gauge and die. NOT overheating, and he has not replaced the thermostat(one of FORDs recommendations)
when it dies It has spark but no fuel. After it cools down it will start and go about 5-10 miles and repeats the same problem
THINGS HE HAS REPLACED:
fuel pump & filter, cam & crank sensors, ignition module, EEC and Fuel pump relays
I think the list is longer but he didn't go into that further.
I have told him to start with the basic stuff. Spark, fuel, timing
Not sure what is shutting the fuel down but HE went and replaced the pump before diagnosing the problem.
I also told him to jumper the inertia switch and see if that does it (had several of those go bad when I worked at the Ford dealer in the 90's)
So what I am really asking is "has anyone else had this SAME problem"?
maybe there is something common that I am missing?
Crank No Start till it cools down has spark and will start on throttle body cleaner
have the same problem?
