Question
I'M HAVING TROUBLE WITH THE FUSE FOR THE FUEL INJECTION IT KEEPS BLOWING FUSES IS THE FUEL PUMP
OUT OR IS THERE A SHORT THAT IS CAUSING THE PROBLEM

Answer
Hi Shane,
Either there is a short, or something connected to that circuit is drawing more power than the fuse is intended to supply.
A fuel injector could be shorted. You can test them with an ohm meter. They should all show pretty close to the same resistance.

Could be a fuel pump just about ready to quit.

Or is it possible that someone connected an add on device to that circuit?

I have been maintaining a fleet of approximately 55 light, medium and heavy vehicles for over 20 years. Most are 4X4 pickups and off road fire fighting trucks. Some medium duty trucks. Some military light trucks. I can answer most questions concerning 4X4 engine, drive line, suspension, electrical, and fuel, both diesel and gasoline. Ford, GM, and Dodge, old and new, but prefferably not newer than 99.
