Lincoln Repair Questions? Ask a Mechanic for Answers ASAP
Hello and thank you for your question,The most common cause for the pump to run with the key off is in most cases caused by a sticking Fuel pump relay. The place to start is to try removing the relay while the problem is occurring. The relay is located in the under hood fuse panel on the driver side. Try smacking the fuse panel and see if the pump stops running, if it dose then that usually means its sticking and needs to be replaced. See the location in the link below.

Are you sure you replace the right relay, it should shut off with the relay removed. There are 3 relays in the box.
Fuse #16 is not the fuel pump relay, it controls the break pressure switch as well as the tun signals, what happens if you unplug the break pressure switch on the master cylinder?
Fuse #16 is not the fuel pump fuse its the break pressure switch as well as the turn signals, what happens if you unplug the break pressure switch that mounts on the master cylinder.
Okay what happens if you unplug the computer?
Okay then the next step is check to make sure nobody has connected the fuel pump prime connector (a 2-terminal connector on the driver side fender apron with a Light Blue/Orange wire and a Dark Green/Yellow wire, behind the windshield washer bottle). If the wires are not connected together at the fuel pump prime connector, the Dark Green/Yellow wire will need to be traced for a short to power between the fuel pump relay and the fuel pump.
The Green/yellow wire run from the relay to the inertia switch where it changes to pink/black to the pump. You have to be shorted to power from the relay to the inertia switch.
You may save your self a lot of head ache by cutting the green/yellow wire at the relay and the inertia switch and run a new wire from the relay to the inertia switch.
