Does anyone know what are common causes of blowing the fuse on the engine relay board for the fuel pump and how to diagnose it? Would a bad fuel pump cause this?
Thanks, |

But, also consider that the heater fan (decent amp draw) and AAR do share that current path. So, place in proper rated fuse, check all wires at those two pieces, and relax (IMG:style_emoticons/default/smoke.gif)
