Hi there! I have been having start problems with my 1993 tt auto supra. Was driving fine all weekend until i parked it for about 10 minutes.
Then when i turned on ignition rpm bounced up and down like crazy and no engine light, there is crank but no start. I have gotten it to start but only with a diagnostic code reader in the obd 1 port in the engine bay. Runs for about 2 minutes then it shuts down.
i replaced the crank sensor but with no change
i did get it to run perfectly fine after moving it to another garage with a trailer. When i got it of the trailer suddenly everything was back to normal. But after a small trip on a bumpy road whet back to not starting.
The car is relatively stock with only a fmic and 255lph walbro fuel pump.
