So, these codes are a clue, I would replace the engine coolant temperature sensor and the ASD relay which are common failures on this truck. If you don't know where they are please let me know.

Code 42 — ASD relay / fuel pump relay control circuit

Code 22 — Engine coolant temperature sensor circuit

The ASD relay should be in the fuse panel under the hood. Disconnect the battery to clear the cods once the repair is completed. Let us know how it goes.

Ok yes I have already replaced them with no luck still said same codes so I bypassed the asd relay but still no start. But getting throttle position sensor high voltage code .also my ground by the crankshaft sensor was broken so fixed that and other ground on the driver side looks like it has been hot .

These are circuit codes so we need to check the engine wiring next, this guide will show you how and I have included the engine wiring diagrams below to help you, if these check out chances are the PCM is bad.
