The amount of fuel delivered to a properly functioning injected car is determined by sensors mounted throughout the vehicles air intake system. These sensors work together along with the ecu to control the fuel / air mix delivered to the cylinders.
We would need to isolate the components that have impact on the duration of time the injectors stay open. In troubleshooting it is often best to work backwards.
1. Injectors - Are they leaking
2. Pressure regulator - is the pressure at the fuel rail the right pressure?? (40psi for most fuel injected cars)
3. TPS- throttle position sensor- is this reading accurately...there are several different styles of these
4. Air flow meter - these also come in several varieties varys from mass air sensor / simple vane meters.
5. during startup there is a separate circuit called the throttle bypass valve - this also may not be functioning if the flooding is occurring rapidly during startup. If the car starts and runs for a while than floods. this is probably not the culprit.
6. ultimately the ECU could have a problem as it is the link in the chain that ties everything together....though not likely.
Any of these these would have the potential to flood a vehicle if they were not functioning properly.
