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. 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. 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.
