Hello,

There is no fuel pump driving module just a relay here is a wiring diagram (BELOW) and a guide to help you test it.

Fuel pump itself is in the fuel tank. Fuel pump relay is at left front corner of engine compartment, in the battery junction box. Also check the fuses and the fuel cut off (inertia) switch, located behind the left kick panel.

In my trunk is located the fuel pump shut off switch, along with a red reset button. There is a ticking sound coming from the reset button and it is depressed as in I can not push it down to reset the system. Now the manual says I can have other mechanical problems. Could this be as simple as replacing the switch? The ticking is killing my battery at which if the car sits for hours it needs to be jumped. Once jumped it starts and runs perfectly, no odd idling or rpm jumps. The fuel pump was replaced at 15000 miles per service records, although I just bought the vehicle a few days ago.

Try pulling up on the red buttom. This switch is the "enertia switch" that's supposed to shut the fuel pump off in the event of a crash. If you can't pull up on the red button, try removing the fuel pump relay to see if the clicking stops. If it stops and starts clicking again when you plug the relay back in, replace the relay.

The wiring diagram supplied only applies to vehicle built before May 24, 1999. If it was built after that date, it does indeed have a Fuel Pump Driver module in addition to the relay, but that was only used for a couple months in that model year. You can tell which system you have by checking for a fuel rail pressure sensor. If it has one, it also has a FPDM. I suspect yours does not.
