Is there any trouble codes stored in the PCM (computers) memory?
Ok, no problems existed prior to changing the thermostat and only connections were removed during the thermostat replace proceedure. No codes exist, which I find very very unusual, especially with a no start condition and the car was fine prior to work performed. You may have a bad ground connection or possibly a ground not connected at all, or a connection to one of the sensors is at fault, but even a bad connection will trigger a fault code. How was the PCM codes read? What tool was used to perform this proceedure?
Ok, I know you smell gas, so what is the fuel pressure. low pressure will cause a no start and NOT display a DTC.
When it rains it pours. This problem is one for the books.

If just change the thermostat, and this car work fine before this job, then its possible that the THEFT DETERRENT (inmobilizer system) is armed. Check in the Owners Manual the procedure to armed and disarm this security feature, keep in mind that this work when the battery is disconnected.
Keep us updated.

The car does not have a theft dererrent system other than the door locks which operate via the keyless fob or manually. No spark getting to the plugs but there is power going to the distributor. Last tune up was 50K ago but it was running fine till I changed the thermostat. Strange !!
PCM scan showed no faults. Crank and Cam were functioning ok.
It was a Snap On model that hooked up under the dash near the hood release. It read no PCM faults and "crank and cam OK" when the key was turned and a start attempt was made.
Problem solved. It is the ignition coil within the distributor that went bad. How this happened to coincide with a thermostat swap out is beyond me. Perhaps it had to do with unfastening the power harness from the PCM to the distributor to get at the thermostat. Anyway this is a costly and time consuming repair. Supposed to be a common problem with these models. Thanks for the suggestions.
"Kind of" helpful. Sometimes these are real tough to diagnose and it means backtracking everything you have already done and that doesn't always reveal the problem. This time the starting system power chain ended at the distributor so that was answer. Big Money and time here.
