Hi, I've got a couple of ideas on this, but wanted to get more input in case I forgot something obvious. This past weekend my DeLorean wouldn't start when the engine was warm, but cooler than normal operating temp. Cold start is fine. Hot start is fine. It only showed up if I left the car sit for a while and the engine temp dropped to around 100 degrees or so. Then, no start. Let it cool down another 1/2 hour and it started just fine. Drive down the road. Stop at a rest area for 5 minutes. Engine is still warm when I get back and it starts fine. It did this to me twice. If it had a carburetor instead of FI, I'd say the choke was adjusted wrong. I'm thinking the thermo-time switch could be going bad? Not completely bad or it wouldn't cold-start properly, but maybe lost it's calibration? Any suggestions appreciated! Mark N VIN 6820
