I drove all day today... it was fine. Drove to Blockbuster, went in and got two movies, came out, and it wouldn't start. Lights came on, air conditioning, windows worked FINE, but it wouldn't crank at ALL. All the sudden I had a check engine light I'd never seen before, as well as oil level light and no oil presure. Opened my hood, and my oil looked fine on the stick...
I was thinking, could it be the security system? I've known GM security systems to occasionally become possesed, and right when I turned the key, my security light came on, but after a couple seconds went off again.
If it helps, it did this for about 2 days when I first bought it, had the mechanics wanting to shoot it until they replaced the crankshaft position sensor, and it hasn't done this since until tonight.
It took me 25 minutes, but at least blockbuster was within walking distance of my apartment.
BAD bonne, BAD!
