hi,the thermostat should had no effect on starting unless in the process a wire was disconected you say there is spark , did you try at least 2 cylinders for fire? did you check at least 2 injectors with the noide light? did you check for fuel pressure with a pressure gage or try spraying some choke cleaner or starting fluid in to the throttle to see if fuel is the problem?
i checked the front 3 cylinders for fire,and with a noid light, fuel was checked with guage, (van keeps flooding) but wont fire, tried starting fluid twice, and it did not work either.
was it running before the thermostat?
yes i drove it into the garage about 20 feet, not long enough to overheat the engine
ok, it seems like everything you need is there fuel injection spark but how about timing or air flow meter do you have a scanner
checking what codes are present will help narrow down the problem.
have you check if the air flow meter is conected?
all timing marks were checked and were ok. dont have a air flow meter
scanner wont tell me anything. i disconnected the battery and check engine light was never on
