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.
