Failure can normally be diagnosed electronically using a handheld scanner, with the model-specific code displayed that translates to the fuel-pump driver module. Difficulty in starting or a smoky start-up, stalling or uneven running while idling, hesitations and misses when driving, and power surges when in reverse can all - separately or together - be indicative of a failing module.

Symptoms of a failing fuel-pump driver module all manifest in the performance of the engine. Pairing the fuel-pump driver module with the incorrect fuel pump will also promote failure. Aftermarket units are available that use advanced electronics that create less heat, with an improved heat transfer pad to minimize retention of the heat. In some model vehicles, such as General Motors vehicles made between 19, the failure rate has been almost total. 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. The fuel-pump driver module is the most common part to fail in computerized diesel engines.

That practice had the module mounted under seats or covered by carpet, which led to overheating problems. Manufacturers, including Ford, initially placed the module inside the vehicle immediately above the fuel pump, typically just beneath the floor pan. 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. The fuel-pump driver module controls the high-pressure fuel pumps of modern, computer-controlled, fuel-injected engines, including diesels. A third type of driver circuit was used by Toyota on overseas models using the 4A-GE engine with D type EFI.

Without this control of the current flow through the injector, the solenoid coil would overheat, causing injector failure.

These can go bad or get damaged from water and will cause a no start or rough running and cut outs in revving/rpm.

Injector Driver Module (IDM), located on drivers side fender.

Other than using expensive diagnostic equipment, what is the best way to tell if you have a bad IDM Injector Driver Module? My van has 264,000 miles on it and it smokes a bit when I start it, and every now and then it 'belches' some blue smoke.

Since the injector driver module runs off the main computer system, a mechanic can hook the vehicle up to a main repair computer to diagnose IDM failure.

An injector driver module can also lose power or receive damage, meaning the fuel injection system cannot function properly to operate the vehicle.

By controlling the voltage, the fuel-pump driver module maintains the optimum fuel pressure and fuel delivery to the engine throughout its full operating range. By either name, the module controls the voltage delivered to a vehicle’s fuel pump. Aftermarket retailers sometimes call the same component a fuel solenoid driver, or FSD. The fuel pump drive - or driver - module is usually referred to by the acronym FPDM.

My van has 264,000 miles on it and it smokes a bit when I start it, and every now and then it 'belches' some blue smoke. I bought brand new in unopened box off ebay for several hundred dollars less than I could anywhere else, from a very high volume ebay seller.
