Fpdm FUEL Pump Driver Module Ford Expedition.

John answeredabout a year agoI'm just adding this thought or what I came across with my 89 F150 5.0 2WD extended cabXLT. I can wiggle or push the wires down by my left foot at the fire wall side to side where itwon't allow it to start, it does allow it to crank but not start. Then I can move those wireswhere it will allow it to start. My truck is acting like the fuel pump is going out, I will need tofind that bad wire to see if that was it. If you think it's your fuel pump, start it then wigglethose wires to see if that creates your problem. With mine it shuts it off.

You also mightwant to wiggle test the wires under the hood. Mine starts to cut off going down the road,but it will start right back up as if the fuel pump can't keep up. But it could be a bad wirethat's shutting down the fuel pump. I can't answer the question that is being asked here, Idon't know if my 89 F150 as a fuel pump driver module. Mine has 3 fuel pumps in the dualtanks system, one low pressure in each tank and one high pressure that mounts to theframe under the driver side seat.

The fuel-pump driver module controls the high-pressure fuel pumps of modern, computer-controlled, fuel-injected engines, including diesels. The module is typically installed on or very close to the fuel pump, and in the early years of the component's use, this practice led to a design fault. Manufacturers, including Ford, initially placed the module inside the vehicle immediately above the fuel pump, typically just beneath the floor pan. That practice had the module mounted under seats or covered by carpet, which led to overheating problems.

The fuel-pump driver module is the most common part to fail in computerized diesel engines. When first installed in the technologically advanced diesel engines of the mid-1990s, the modules were made from materials that were unable to handle their own high operating temperatures and the extreme vibration they were exposed to when functioning. In some model vehicles, such as General Motors vehicles made between 1995 and 2002, the failure rate has been almost total. Aftermarket units are available that use advanced electronics that create less heat, with an improved heat transfer pad to minimize retention of the heat. Pairing the fuel-pump driver module with the incorrect fuel pump will also promote failure. Vehicles with modified engines that need more fuel than is standard, such as race cars and tuned-up street cars, require modified FPDMs.

Running a standard module can result in overheating - the standard fuel pump asks too much of the module, and its electronics overheat - so the internal limiter shuts the control process down. Although the module should resume function when it cools to a safe temperature, the sudden cessation of fuel flow to a full-revving engine can have catastrophic effects.
