My wife's 2002 explorer has a very weird problem. If the temperature is above 85 degrees, she'll get in her vehicle and drive it home. When she shuts off the engine, it will not start again. If I lay under the car, and have her turn the key to the on position while the car will not start, I can not hear the fuel pump come on to pressurize the fuel system. Once the evening comes and the temperature cools, the vehicle starts right up as if nothing is wrong with it.
If the temperature never reaches the mid to high 80's, the vehicle will not fail. I changed the fuel pump relay and that was not the problem. Could this actually be a bad fuel pump even though it works fine when the weather stays cool or if the vehicle is not shut off when it's hot outside?
have the same problem?
