Ok so alot has already been replaced on the car. But the fuse #56 INJB keeps blowing everytime i turn the ignition on and before it just wouldnt crank replaces altenator etc. Please help im tirex of being stranded what do i do!!!
Fuse 56 feeds the starter/ignition from what I see on mine now that I am home. What other parts have you replaced? I'm sure other gurus such as Brandon have more experience in this than I do. But I'd check the wires to the starter. Possibly internal short on ignition switch.that's a cheap/easy fix. Since it blows when going to on position (unless you mean trying to start the truck). Could try pulling fuse 29, 31, and 33 from the under seat fuse box and see if that stops the issue. From there you'd have to chase down the offending culprit. I need to find the full circuit diagram to be of more use after that.

Here are the diagrams from Brandon. Hope it helps. I was off on my above statement (this is why I search Brandon's posts for all thing electrical).
