Engine Mechanical problem
2001 Ford F150 V8 Two Wheel Drive Automatic 76000 miles
I went out the other day to go on an errand and when I turned the key to start it, it turned over fine but would not fire. No stumbling. Just the sound of a healthy starter turning the engine over. I took a shot in the dark and wiggled the fuel pump relay. Presto the engine started and worked fine all day. Next day the same thing occurred but this time wiggling the relay did not produce the same results so I removed the relay and promptly replaced it and then the truck started and worked fine all day. I then assumed a defective relay and bought a replacement and installed it. Next day I went out to test the truck to see if it was going to start and it did and I thought the problem was solved. WRONG!
I went out today and it will not start no matter what I do. I tried replacing the new relay with the old relay to see if that would have an effect and it didn't so I am dead in the water with no ideas. There is no " Check Engine" light on or any other indication of a malfunction. I have checked all fuses and the gas tank is 3/4 full.
