double check your crank sensor

code p2101 throttle accuator just came up..how would i check that?

Not sure, sounds like something might be unplugged. I'd check connections and fuses. Make sure everything is clean.

 

I think some crank sensors need to be gapped. I don't know on the 6.0, I've never worked on one.

unplug scan tool, unhook battery for 3 minutes, and then re hook up battery and test, leave scan toool unhooked. Dont put truck in gear with scan tool installed

If you replaced the crank position sensor then you may need to have a crank relearn done to correct that problem.
