    Electrical problem, need shop

    Hey folks,

    The jeep won't start and I've run to the end of my knowledge and troubleshooting techniques. Took it to a local shop and they don't want to touch it due to the amount of aftermarket mods and PO shoddy electric messes. My battery is good, I've checked all fuses, relays, and basic wires and it just won't start. It behaves like the park indicator switch is not working, but I have no way of checking that. Know a shop locally that will take this on?

    Thanks!

    Did you try starting in neutral?

    Give my cousin a call. I can't say for certain if he'll be comfortable with the work, but I know that if he does, he'll be fair and I doubt modifications scare him.

    Crankshaft position sensor?

    Are you are dealing with a "no crank" issue, or a "no start" issue?
    If you cross thread a bolt, there is no need for loctite.

    Run whatcha brung... And hope you brought enough.

    He mentioned the "Park indicator switch" which makes me think it is a no CRANK issue

    Correct. It's a no crank. Battery is strong/tested.

    Can I bypass everything and take 12v straight to the starter?

    Yes you can. Use a screwdriver, or anything else metal to jump the small posts on the solenoid. If the starter kicks in then you have a problem in the switching/sensing area. Eliminates the starter solenoid as the problem.

    Another possible source of problem?:https://www.youtube.com/watch?v=RdrcAgFSWgk

    No crank usually = bad relay.

    1. Find the starter relay (no idea what number it is).
    2. find another relay somewhere else in the fuse block that is the same
    3. switch them
    4. if it cranks = bad relay
    5. no crank = another problem

    To keep from confusing the poster- a crankshaft position sensor will NOT solve his no crank issue.

    So i Jumped the starter and it cranked, but no start. Finally took it in and they discovered it was a failed transmission temperature sensor. They also think this is the cause of my overdrive which periodically turns off by itself when I'm city driving. In taking the transmission apart to replace sensor, they discovered more wear and tear and so I'm trying to determine whether or not to rebuild tranny (auto). Sigh.
