    Anyone know of a bypass?
    I seem to be encountering a issue at times where I will turn my key one click and nada.
    dash lights up all is engaged...
    wait or try a few times and it will eventually start up?
    Battery good,
    ground good
    starter good...

    I do NOT think that (NSS) is the issue.

    And being Sunday I can not get a diagram to attach for troubleshooting.


    thinking TIPM or starter coil driver

    Here is the diagram I have from Alldata... It looks like C1 (Yellow w/ dark blue stripe) is noted as Park/Neutral and you would want to ground it but the other switches aren't marked so I am not 100% sure.

    If yu ground circuit T41 (YEL/DKBLU) then shift to a drive gear the PCM/TCM will have issues. P/N and drive at same time.

    What does your scanner display as trans position when it will not start, does it show trans in gear?

    There is NO remote POS on this jeep?
