Why would the fuel injection system fuse blow when you try to start a 97 Geo Tracker?

I have no idea why, but I do know a fix. Mounted to the bottom or side of your ECU is what appears to be a great big relay or contactor. If you unplug this connector and inspect both the inside of it as well as the contactor, you're going to see one pin that has been obviously overloaded. It will be charred on the connector side and melted on the relay/contactor side. The fix for this is simple, Just disconnect that pin. I used needle nose pliers and pulled it from the relay/contactor. You can just cut the wire, provided you protect the cut wire from shorting out properly. Now, I have absolutely no idea what this does. On my vehicle, it simply fixed it. But the year previous I had been having fuel pump wiring problems, and had put the fuel pump on it's own switch. It *may* trip the fuel pump relay or something. This is just a guess however, because it caused ZERO effects after I clipped the wire. I have no idea what that pin does or what it's for, other than to cause the fuel injection fuse to blow. =)

for people who were not born in barns you may know this answer, those of you who were born in barns, yes the wires will short out when they are sitting on the engine block or even possibly by fair chance in hell the heater hoses rubbed them....but i highly doubt that would cause the fuse to blow. you may need to have an expert check your wiring system before you get in your car and start driving it around, if the fuel injection system blew then you may have a fairly good reason NOT to turn on the engine. rewiring may be what is needed.

a 1998 Tracker would be fuel injected and not have a carb.a 1998 Tracker would be fuel injected and not have a carb.

If the vehicle is equipped with a fuel injection system, it may be clogged. When a vehicle has fuel injection, the gas pedal does not need to be depressed to get it started. It sounds like the vehicle needs to be taken to a mechanic.
