Heater went along with speedometer and odometer, have changed speed sensor, instrument cluster and computer, Still no change, Have opened the wiring harness check for corrison, broken wires, cleaned wires on starter. Have checked the power distribution center. Since all this lost all power to starter, anc oil pack. But if jump the starter it engages but does not start. Have check the ignition switch and printed circuit in junction box. Just stumped now as to what is wrong. Was on ramps and have since lower to level surface in case auto shutdown kicked in

When you say heater, do you mean blower motor?

Does it work on any speed or all speeds are inop?

3.3 motor?

MAkes sense it doesn't start if coils are not powered when starter is jumped. Let me know above.

The coil is powered from the asd (autoshut down) relay, did you check that relay?

Heater core leaking?....not following that part.

Anyways, check the connector at the BCM where I circled it. Check for corrosion, bent pin etc.
LAst two diagrams may be irrevelvent, but you have them anyways.

Orange wire to crank and cam sensor is run position gets only 1.5 volts. When cranking over engine orange wire gets 2.7 volts. Manual says 8 volt supply. The big pink wire going to the ignition switch which is possibly a 12 guage wire has only 5 volts. Did taje ignition switch apart. Had a little arc present. Cleaned and sanded terminals. Orange wire going to junction box inside vechicle was repaired. Appears had melted and was repaired before. Checked BCM NO corrision, bent pins etc. The diagrams that u sent are hard to read very small on computer. Tried to enlarge but goes to blurry. Any way possible to enlarge the area that was circled so that can read and not as blurry. Still no change cannot locate what the problem is checked everything but seems power being drawn away for starting circuit. But thank you for the diagrams
