I was thinking crankshaft position sensor too, code P0320. Check your fuel pressure at the Schrader valve on the fuel injector rail (55 psi). Or at least replace the fuel filter which includes the fuel pressure regulator. Scan for codes too.

Has several codes ,about ten to be exact but I would like to think it is the fuel pump or a delivery problem as well . That’s the only 2 things that have not been reprogrammed also I might add. Another question how important is it to get the pcm reprogrammed to the Jeep after pulling one from a junkyard ?
