    No voltage on the trigger to the Started relay. Turns when I put voltage on the trigger. I'm trying to test the NSS. Batteries went dead so I'm charging them now.

    Thanks. I do not have anything on the control side but when I jump out the relay it turns the motor. I have a cheap OBDII tester but it seems to be communicating. No luck yet. Thanks for your help.

    I charged the batteries, headlights are strong wiper work heat works. I will try to test the ignition and park neutral switch next.

    Late 2007...2008 style LMM No start No Crank. Tested fuses, if anyone has the pinouts for the ECM and TCM that would help me chase power and grounds. Thanks.

    The Truck has been sitting for 6 months. It ran just before I parked it. Now I turn the key and nothing at all. Lights, Heater and wipers work no windows or radio. Any place to start will help.
