car starts o.k.,[cold] runs o.k., but if driven approx a mile or more to destination,then shut off. After about 5 to10 minutes later can,t start it to return home. Turns over good, but won,t fire up unless you wait until it cools down. Been told might be fuel pump or fuel filter. Do you think they are the problem? Could you also tell me where the fuel filter and fuel pump are located and how to access them. Thank you.
won't start when hot,only when cold on 1991 GMC Safari
This sounds like the Ignition Module/ Pick-up coil in side the distributor. Pretty common on GMs. If it was the Fuel Pump, it would not be so intermittent and would not be so sensitive to the heat of the motor. The Ignition Module will do this type of symptom and is very common.
I also had this similiar problem, cold start was great but after a few minutes power would drop off when motor warmed up: Bad distributor cap\rotor (after we changed the fuel pump)
