OK...fast forward...I determined that the OEM switch is garbage and the eBay seller won't refund my $ since it was "installed" (I guess around my tumbler & key?) Whatever.
So I bought a switch from Auto Zone. It ohm's out across the IGN1 and batt terminals, and I've confirmed I have 12v to the IGN1 terminal with the key on. Car starts but dies when the key is turned to Run. Bought another one thinking something is wrong with switch #1. Nope...same thing. But one thing I DID discover was that after putting my original switch back in, and then jiggling it, the car started and ran until I bumped the key. I've not been able to do that with the AutoZone switches.
Any way...what the %$#$ gives? What's the %$#@ing problem? Every aftermarket switch can't be bad! Plug looks good and uncoorroded. I have no %$#@ing idea what's %$#@ing wrong! Can anyone offer some enlightened suggestions before I start bashing $#!t in my garage with a %$#@ing hammer?! I just want to enjoy my car!!!
