So my car starts fine when I turn on the ignition and run the starter with a remote start switch, but not when the key turns powers the starter? This makes me suspect that the ignition switch is turning off the ignition while in the crank position. Is this a common failure point of these switches? or should I be looking somewhere else?

Spent some time with the six wiring diagram tonight. It appears that the only thing that happens when the ignition switch is rotated to crank is the starter is engaged. All of the same components are energized by the same set of wires that energize them in the run position.
So why does some of the ignition components perform differently in run than they do in crank? Why does engaging the starter improve the ignitions performance? Stumps me |
