Put transmission back in truck now starter won't work

What is the starter doing? If it is doing nothing at all have you checked the nuetral safety switch on the transmission?

If it is just buzzing or trying to turn the motor over then remove the starter and make sure your flywheel isn't bound up.

Starter fix (bad wire) now truck won'y go acts like brakes are locked up brake light is on and won't go off checked brakes and fluid all is OK.
