It's definitely a bad connection somewhere. I don't know where, though. I was pressed for time today, so I didn't get a chance to do a lot of troubleshooting.
I boosted from my GFs car, to mine, without hers on. Nadda. I then took off the jumpers and moved the car (someone needed to park). Set them back up again, and this time turned her car on. The stang fired up right away.
I let it idle for about 10 minutes...temp gauge sat still.
Shut it down, and took off the cables. I had ran out of time at this point, and I went to press the power lock button. Interior light dimmed and flickered, and then the power went out.
So there's clearly a connection issue somewhere. It seems intermittent.
What I've written above would rule out the starter as an issue, correct? It obviously works, but is there a chance that there's a bad connection on it?
Where else should I look, or what steps should I take from here. I can't do anything on it that would involve getting it on jack stands until I can drive it out to my parents place.
Lastly, is there any chance that this bad connection was what caused my car to overheat?
