Happens every day (average 3 times a day in the towing company I work for )

這種狀況還不少哩 ~~~~~~

(1) If the engine was not started, drain the system and refill, and you're done.
Draining the tank is very difficult and should only be done by an authorized dealer.
(2) Once the engine was started the fuel pump might need to get replaced.
(3) If the car was driven and died, you need a new fuel pump.
