Once you have added fuel to the tank you will need to cycle the key at least ten times. Turn the key to the “ON” position and back to “OFF”. Do this ten times. WHY? When you go to start your vehicle the fuel pump relay only activates for a few seconds and is not enough tome to prime and empty fuel system. So by cycling the key several times you are filling the system and should be ready to start. Comments are closed.
