This happened 1 other time about 10 months ago. The car was at a shop getting the oil changed and when I went to pick it up,it would start, didn't even turn over. The mechanics came out and said it worked fine fro them. They worked on it for maybe 5 minutes scratching there heads. I went to the bathroom and when I came back it was runnig. They said there was nothing wrong with it.
Today I moved it to work on another car and when I went to put it back about 2 hrs. later, it wouldn't.start or even turn over. Any ideas ( Could there be a dead spot on the starter solinoid)?
Thanks in advance

I was guessing that the fuel filter was changed when the guys were changing the oil. Mine wouldn't start after it was changed. No idea why it wouldn't start when it was left for 2 hours..

 

Looked at a couple other sites and someone said it might be the Nuetral switch. Someone else suggested spray some electrical contact spray in the ignition where the key goes. I tried it and also Swithed from park to nuetral a couple of times and the car started right up. I'm leaning towards the Nuetral switch but it seems to be working fine now. Thanks for all the help
