I have a 2001 f350 superduty and had problems so had put on code reader told me it was bad so now 1000.00 later no one can tell me where it is located so i can change.anyone help!!!

 

It's behind the inner fender well on the front driver's side (towards the cab.) Yeah, I know, not exactly obvious, eh? (The official part name is Injector Driver MODULE, or IDM; it's not a computer but just a power supply and some injection drive circuitry.)
