Engine Mechanical problem
1987 Ford F250 V8 Two Wheel Drive Automatic 150 k miles
My basic problem is that my truck won't start. It was running and stopped and now I can't get it to start. It is a fuel issue because I got it to start (momentarily) with some gas in the carb. I checked obvious fuses and also changed the fuel pump relay. My truck has the 7.5 liter 460 engine. It is carbureted and was sold in California. My understanding is that carbureted 250's have a mechanical fuel pump, with the exception of some of the 7.5 liter models. This truck has two fuel tanks and so I thought that if it has two in-tank pumps it would be unlikely for both to go at once. My manuals don't spell out for me what the pump or pumps on my truck would be (mechanical or electric). So my questions are: what kind of pump system do I have? Where is/are the pump/pumps?
Mechanical pumps are on the front of the engines if I remember correct. Electric pumps are in the fuel tanks themselves usually. Follow the fuel line from under the vehicle, to see if it goes into a pump, or into the fuel rail. If it's electric, check to make sure you've got power and a good ground for the pump.
