03 HPDI 175 bad ecu ?
Got a customer did a pretty dumb move. Turned his battery switch off while under way. Motor quit and alarm went off. Had to be towed in. I replaced the fuse for the control unit but no start. The fuel pump will not run when keyed, but checks good.The motor will not scan. Can not connect to ecu. The relays seem to be fine. I'm pretty sure the ecu is fried. Any thoughts or opinions greatly appreciated.
