10% chance it is the relay and 90% the fuel pump. Good luck

If you smell gas and the fuel pump fuse is blown it is residual fuel. I strongly suspect you have a bad fuel pump. It is a bear to replace as the tank has to be dropped. The less fuel in the tank the better. Good luck and don't get confused, it is a simple problem.

If the fuse is blown, key on, the pump can't run unless you have a major wiring malfunction.

The fuel pump is in the tank and a bear to change, make sure the tank is low on fuel when you drop the tank. Below is a listing of different pumps that apply to your car. Good Luck

Humm Looking at the schematic I see that there is an impact interia sw that opens when you have an accident killing the fuel pump circuit. The pink and black wire goes to the fuel pump and the dark green and yellow goes to the relay. That wire also goes to the ECM.

You might want to check out that circuit. The sw is located in the trunk. Good luck

We have replaced the fuel pump switch and the relay. But still blows a fuse. Could there be a wire grounded and or something. Is there a diagram on how the wires run from the fuel pump to the relay and shut off switch and the fuse box.

To check the wires to the relay- remove the relay, remove it and turn the key on. No blow wires are good.

There is no physical lay out of the wires only a schematic.

But I would un-plug the switch and turn the key on. If the fuse blows it is in the relay circiuit.

Next un-plug the fuel pump. If it blows then it is in the wiring. If not the problem is with a bad connector on the tank side of the pump. It is common on Ford trucks but rare on a Town car.

The only thing between there is the self test socket and the computer with the realy out of the circuit. Unplug the computer and try it. If it blows we'll look further

You have to physically trace the wire by hand. This invilves opening the wiring harness. At least you isolated it to a wire and not a processor. You will find a nick in the wire and it will be eay to find, just patience and persistance.

There is no wiring layout as each car has a little different twist in the wires. Pull the fuse and the relay and use an ohm meter to find the short Good luck
