My car is getting to much fuel and will not stay running. When i start the car it dies right away so i turn off the deflooding switch and start it again. It will run a few seconds but as soon as i turn the switch back on so the fuel pump is running the car dies. I am new to the rotary world so i am looking for some input on what this could be and some places to start to diagnose the problem. Thanks in advance.
