I have a 1990 Toyota Celica, and I’ve been having trouble with it not starting after driving. There are no symptoms when the car is running, aside from a very slight rough idle. The car starts fine after sitting for 3-4 hours, but for short trips where it’s off for under 1-2 hours, it cranks but will not start. The cranking also seems weak unless I floor the gas while trying to start, and sometimes it will eventually start if I hold the gas while cranking. It always starts at the beginning of the day.
This leads me to believe I’m dealing with a flooded engine, but I’m not sure how to diagnose why. I thought it might be leaky fuel injectors, but wouldn’t that cause symptoms when running?
