Fuel Pump

So today when I got home from work, pulled in driveway, shut her off, got out and notice that even though she wasn't running the fuel pump was humming a buzz song until I disconnected her battery.

Anyone else had this same problem?

What I know about trouble shooting EFI is somewhere between none and none whatsoever but is it possible there is a relay/solenoid some where in the system that has gone bad?

There is a fuel pump relay on the driver side fender apron -There are two relays the fuel pump and the EEC (ELECTRONIC ENGINE CONTROL RELAY). The EEC relay runs the fuel pump relay. Replace both. When you turn the key the EEC relay energizes and provides power to the computer and provides a circuit to the fuel pump relay.

Thanks for the help. I have to get out the book and track down those relays. Looked them up on autozone etc, and not finding anything. Where do you guys order your hard to find ford truck parts?

I've ordered some from LMC (Long Motor Company) of Lenexa, KS. They have an online source and will also send you a hard copy catalog upon request.

LMC Truck Parts: Chevy Chevrolet Blazer S10 GMC Jimmy S15 Ford Bronco Ranger Pickup Pick Up Accessories/Catalogs

They seem to be quite proud of their parts.

There are, or were, a couple of companies that advertise on this site too but I don't recall the names.
