It all started one day when I hit a pothole really hard. The fuse blew and fuel pump stopped. I changed the fuse and was good to go until recently when it started blowing again. Now, everytime I am under a load, like plowing through snow, the fuse will blow. This past weekend, my fuse blew again but this time I can't get it to stop blowing. Everytime I turn the ignition on, I blow the fuse. The fuse is located in the slot marked ECMI. How do I find out if it is the pump, the relay, or anything else? I am assuming there is a short somewhere. I thought maybe I pinched a wire and am arcing out somewhere. There is one black wire and two other wires coming off the tank where I am assuming the fuel pump is. The wire tester just barely has a dim light on one of the wires and nothing on the other. The problem is when I turn the ignition on to test the wires, I blow the fuse. Any suggestions? Thanks. Rob in Wisconsin.
