    My tj performed excellent all Labor Day weekend at Powerline Park (Saint clairsville, Ohio), however after power washing the thick coat of mud off when I got home I ended up with a crank no start. I'm getting no power off the ignition coil and the connection going into the coil is only reading 4.3v. I've checked all of the grounds near the coil and they're all returning 12v. Ecu?? Thanks for any help with this strange issue

    Did you power wash under the hood too? blow out all electrical connections with compressed air. Make sure everything is dry under the hood. Sounds like something is wet and shorting out.

    If you have no spark check the crank sensor and see if the connection has water or crosion
