73 390
I am not a Ford guy at all, but I have recently been looking at old Ford trucks because I need a beat up old work truck that could take some more abuse. I found a 73 F100 Ranger that had been used for a Farm truck. It has a 390 and was said to run although it won't fire now. He said it has been sitting for about 5 months. It has new plugs, distributor, coil and wires. It will crank but it won't fire. Other than the possibility that the rotor is missing or on wrong, I figure the fuel pump is bad. He said I can work on it whenever I want. He only wants 300 for the truck (Its a little rusty in the bed, but in great shape) so I figured I would swap fuel pumps and see what happens. Anyone have any advice? I have never messed around with old Ford engines I don't even know where the fuel pump is located on a 73 390.
Thanks

The fuel pump is located at the bottom of the engine on the left front side. It can be fairly tricky to get to especially if there is a huge accumulation of grease and grime down there...good luck.
If the truck ran a few months ago, I'd bet it is more of an electrical problem rather than fuel related. It should be easy to isolate. First, check for spark at the plugs by inserting a screw driver into the plug boot then holding near somthing metallic while another person turns over the engine. Second, check for fuel at the carb by disconnecting the fuel line into the carb then cranking. Once you isolate the problem, you can easily fix it.

[font size="1" color="#FF0000"]LAST EDITED ON 21-May-01 AT 08:57 PM (EST)[/font][p] look around here, I have a electric fuel pump, but the stock one goes there (the yellow circle) Also take about 8-12 inches of fuel line with you and replace the piece that goes from the frame to the pump as it has failed internally and plugged itself on me before.

Before disconnecting anything, just put a few squirts of gas down both throats of the carb. It should run for a second or two if the ignition is working properly. Make sure you put the air cleaner back on before you crank it, otherwise five months worth of dust & dirt will get sucked down.
