I was going to work and I was at a stop light. While I was waiting for the light I decided to fix my rear view mirror so I did a quick fix with mounting tape and plugged the electrical part for the map lights and the truck shut off. It didn't start at all and had it towed home. What can it be?
Do you

Hey Peanutg13,

It sound like it can be one of two things, either the crankshaft angle sensor has gone out which will make the engine have not spark or injector pulse or the fuel pump has gone out, here are some guides that will help you figure out what is going on.

I don't have the tools for
Most of that, what u did find out is that a fuse of crankshaft was broken so I replaced it but it still didn't start. I would think it would be an electrical problem seeing as when I plugged in the rear view mirror lighting the truck shut off, also I noticed that after the truck shut off I unplugged the rear view mirror and when I plug it in it's on and won't go off even when I turn of dome lights and close the door

Hey PEANUTG13,

Yes this does sounds like a BCM problem that will need to be replaced or the wiring damage found and repaired. Here is the wiring diagram for the BCM so you can starting looking around. It does look like there is a heated mirror relay that is tied into the engine ignition fuse. Try removing the relay to see if that helps.

Please run some tests and get back to us so we can continue helping you.

I found out that it was the "ecm b" fuse. So I replaced and it and it started right up but as soon as I accelerated, the fuse blew. So I asssume there is a short somewhere. I put a higher amp fuse to move it back into a parking. Do u think it will run with that higher amp fuse or should I just look for the short?

Hey, PEANUTG13

Good find on the fuse, I would look for a short. Start the truck up and let it idle. Then start moving the wiring harness around it see if the truck stalls, this will give you an idea where the short is.

Please run some tests and get back to us so we can continue helping you.
