Fuel pump prime once every X amount of time?
My 2013 L99 engine has this thing where when you go to start it up, it would prime for a few seconds which I know is normal.
But what I have noticed is that if you shut the car off a few minutes later and go to restart it, the pump would not prime. If I wait say 30 mins, than it would allow the pump to prime. Is this normal and what can I do to make it prime on every startup regardless of time? |
