Q: Car not starting sometimes

asked by on November 30, 2016

My van starts right up in the morning but after being driven for a while it sometimes won't start again and I have to wait about an hour until it will start again. Unless the car is failing, no one can diagnose it and it only fails at the most inopportune times. I've had some ignition thingy (technical term) replaced. I have a new fuel pump and spark sensor. It's baffled a few mechanics. It turns over just fine so it's not a starter issue. It just keeps turning over, and over, and over... Any thoughts?

My car has 147000 miles.
My car has an automatic transmission.

Hi there.
