91 corsica 2.2l fuel pouring into throttle body

[Steven1977]

I have a problem with my 91 corsica. i get alot of fuel pouring into the throttle body when i crank the engine over. Now i have replaced the fuel injector and the fuel pressure regulator, replaced spark plugs and i do not get any codes i have tried to reset the computer. I did get the car to idle after replacing parts but after i put it into drive and tried to move the car the engine stummbled and died. Checked and found fuel pouring back into throttle body when cranking. I let the car set for a few hours and tried again and result was the same thing. I am at a lose at this point any ideas and help would great. thanks

I've had a bad thermostat and the mileage dropped 50% it acts like a choke is closed and calls for a lot of fuel. You can also have a bad temperature sensor.
Feel the engine radiator hose and you can generally find a bad thermostat.
Use a pressure gage and actually check the pressure.
