Sounds like you probed the wrong wire and damaged the PCM.. What codes are in the PCM?

Hello and welcome to JustAnswer!
P0841 is setting in the TCM. The PCM is the module that controls the engine. I'm certain that it's not awake if the ASD and fuel pump relays aren't being controlled. Your truck has an a/c pressure transducer rather than a switch and if power or ground was jumped at it's connector then it would have damaged the PCM.
Another sign that the PCM is down is the voltmeter and fuel gauge most likely won't come up with the key on.
If the PCM is down it could be an internal failure or a loss of power or ground. In this case the failure is most likely internal since the problem happened from jumping terminals at the a/c transducer.
If fuses are good it would still be best to test the PCM powers and grounds before condemning it, but it has almost surely failed.
