there are many potential problems, but I'd start with fuel delivery. Check fuel pressure and make sure the fuel filter isn't blocked. There should be a fuel pressure test port just below the fuel injector rail supply line.

I have a problem with a 2000 LW1 saturn. It's an intermittent problem. Ocassionally will not start until today. Today the car had to be towed, it would crank over but not start. The crank position sensor and control module have been changed. The problem is still there. The fuel pressure is at 55 (between 50 and 60) so that rules out fuel pump and fuel filter. Not sure if it is getting spark. I used a spark tester and it didn't look like it was getting a spark. I was told it may be a temp sensor? Not sure what to look at next! Please help!! Don W Michigan
An auto thermostat is strictly a mechanical device, so no.
