Well after checking into the no start issue, I believe that I am experiencing an issue with the TCM. Also found out that my keep alive memory is showing a fault, 0 volts. The truck will not start unless persuaded to do so by jumping the starter wire and then it won't move in a forward direction except in 3rd gear only. Reverse works, but no reverse lights, and the parking sensors are also not functioning. Does this lead anyone else to believe that the TCM has died, or could it have something to do with the power supply to the TCM? I cannot find where power is supplied from for this unit.

Thanks-
