Hey! Im working on a 75 F-150 Ranger also that was my grandfathers. It sat for about 12 years. In the last few weeks I have replaced the water pump, master cylinder, alternator, battery, starter, solenoid, plugs, and plug wires. I cranked the motor by hand first and it turned fine. When I try to start it it just clicks. On the old starter there was small thin peice of metal that looked like a jumper maybe. The old starter was tested but only worked with that peice. Of course that is the only peice that I can't find now. No one seems to know what im talking about. My buddy is a mechanic and he said that this truck is different then all the other fords he looks at because there is a solenoid on the firewall and also one on the starter itself. Im hoping you know what im talking about, and maybe you have that part. The truck only has 60,000 original miles and was running perfect when it was parked. Im really frustrated!! Hope you can help.
