Have Ford Questions? Ask a Mechanic for Answers ASAP
Thank you for the tip on the fuel pump shut off switch, However there is no power in or out of the switch. It was located next to the kick panel just like you said but my problem is still there. Any further advise would be greatly appreciated by this back yard mechanic.
You are correct, there is no power to either pump. I just checked for a clicking in the relay and there is none. So seems to be a power problem?? I was driving the truck home and it just stopped running apparently losing power to the fuel pump when this all began. Thank you for any further imput.
I am locating a voltage tester and when I get the reading on the relay I will get back to you, but it probably won't be until tomorrow evening. Enjoy your afternoon.
Dont know how you stay awake in the heat from your wood stove, maybe you didn't!
Well, I replaced the EEC Relay and put a test light on the yellow wire at the fuel pump relay while cranking and there is no power. Hope you can steer me to a solution.
This feels like it could be the problem, however it will take me and evening or so with my schedule to determine if this is it. Thank you for sticking with me and I will let you know what I find. This has been a reliable old truck and thank you for trying to help me keep it going.
Talk to you soon.
I apologize for taking so long to get back to you. Wednesday evening I did discovered a corroded end on the fused link. I repaired the end and now have power at the fuel pump relay yellow wire. However, now I do not have power at the power at the fuel pump shut off switch. Can I jump the two wires at the shut off switch to see if my fuel pump runs? Could one problem have caused another?
Mikey if you are still there, I just cranked the engine over and there is no clicking sound at the fuel pump relay, so am I back to square one?
Going to go watch a movie for now. I'll do a little more investigation tomorrow. Thanks for your time. Talk to you tomorrow.
I have been suffering from a poor ground on my test light. Today I ran a good solid ground wire for my test light and have discovered the following. With the ignition in the on position and while cranking I have power to the fuel pump relay yellow wire. With the ignition in the on position and while cranking I do not have power on the EEC Relay yellow wire. Is this better or worse?
Thanks for your continued interest
That will give me something to check out in the morning. I don't want to leave you hanging tonight. Have a good evening.
You have been a trooper. I truely appreciate your efforts in resolving my fuel pump problem, however it has taken its toll on my patients. I had the local Ford garage come and get the truck today and if you like I can write you back what the mechanic discovers. Kudos to all professionals in your line of work trying to decipher problems such as mine. I have checked the accept box because I feel you have helped me as best you could under these circumstances. I hope your favorite team makes it to the Super Bowl and keep the wood stove stocked.
