    Wonder if you have a harness issue? You can send the ECM off for testing before dumping that kind of money on a new ECM.

    I had a mechanic troubleshoot my Jeep after I just couldn’t figure it out...ECM. Come to find out it was a 40.00 sensor. 650.00 waisted. Still have it in my garage.

    Checking for continuity on each wire. Takes a bit with a militi meter.
