Need Help--Electrical/starting problem

[StephenVA]

When weird electrical issues pop up on start cycles, look at the Ign S/W as that issue is common across all vehicles since they invented the damn thing in the 60's.. Older models would smoke as the carbon pins shorted out. Now days you get nothing. Hi turns in every parts line across all manufacturers.

As posted, many items that energize with key on, will not work as the s/w fails.

Examples: No voltage moves to starter, ignition, accessories, etc, as the switch is the source of the circuit connection failure. GM actually makes a specialty tool to eliminate that failure test.

At times you can just smack the s/w and it will work for a few cycles until total failure.
