Yesterday I changed the transmission in my truck, it's the same transmission it came out of the same year model truck exactly identical. I put everything back together, now my truck won't start. I checked the starter, all the lights are coming on my dash, but it's not even turning over. Can you please tell me what would be the problem?

Hi,

By chance, do you hear anything when you try to start, such as a click?

If you look below, I attached the wiring schematic for the starter. There are several fuses that should be checked.

In the under-hood fuse box, ign A, ign B, ign, E, and the crank fuse. Check to make sure they are good. It's easy to have a slight short when working that causes a fuse to fail.

Let me know what you find.

Take care,

Joe
