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. Re: injector driver module problem My truck kept throwing the same IDM codes while missing, knocking, etc.
