I figured this out last night. It was a loose connector in the engine bay.
I got under the hood and jostled some wires around and then decided to try and turn the key to start it. It started up. I had to jump it, but it started. I was genuinely perplexed, again.
With the engine running, I got under the hood and jostled the same wires around and when I touched the big connector attached at the top of the cowl, the engine died. Bingo.
On one hand, I feel dumb because it took me so long to figure it out and on the other hand, I’m just glad it’s back!
LET’S GO WHEELIN!!!
