My trailer lights stopped working, checked fuses and found one blown. so I changed the fuse #10, tried turning on lights then blew again. Then figured out I had a wire rubbing metal, fixed that, replaced fuse and now all trailer lights work.

Went to move truck and could not get it to start. It will turn over but never start. I checked (visually) all other fuses and can't see any blown. What else should I check and do I have to pull each fuse to test?

I would bet its another fuse blown. Sometimes you have to pull the fuse to determine if they are blown. I have visually checked them in the fuse box and they look good only to find one blown by removing it. JMO

 

The only way to positively test a fuse is pull it and use an ohmmeter.

 

It was the fuel pump reset switch to the left of the fuse panel under passenger side dash. Somehow it tripped.
