I have a '94 Ranger with 130k miles.
Sometimes my truck will not start. It used to only happen on really hot days and now it will happen at random times. I lived in TX and NC. I have replaced the fuel pump, fuel filter, and fuel pump relay switch. I have taken it to a shop and they couldn't get it to fail to start. I can wait a few hours and it will start up with no problem. After replacing the relay switch, when it doesn't start, I can turn the ignition and hear the fuel pump activate; before I don't think that it always would. The starter will engage but will not turn over. It really just sounds like it isn't getting any fuel.
