Question about 1999 Ford Explorer
I have a 99 Ford Explorer Eddie Bauer with a 5.0L. The engine will turn over but it will not crank. I have replaced the fuel pump relay, the PCM relay, the fuel filter and checked the inertia switch. I had someone turn the key to on while I listened under the truck and I can hear a low whirring from inside the tank. So I assume the fuel pump is working. I checked for spark and both coil paks are producing a big spark. If I spray starting fluid into the throttle body, it will run until the fluid is gone. I am completely at a loss as to what the problem could be. Could the fuel pump be working at a low enough voltage or something that would keep it from pressureizing the syatem? I was thinking about installing an external electric EFI fuel pump. Is this a bad idea and if I do install one, should I disconnect the connector to the pump in the tank? Any ideas or bonnafide help would be greatly appreciated. Also can I use a paper clip to get engine codes through the check engine lamp? Which pins do I short? Thanks to all who reply!!
