2009 f250, 5.4l cylinder hydrolocking
Ok let me start by describing what I have found out. Number 7 cylinder is pumping so much gas it spits out the spark plug hole with plug out when cranking over. This is the only cylinder doing it. Know here is what I have done. New fuel pump in tank, new fuel rail presure valve, new fuel pump control modular and new injectors. What would cause number 7 to fill up with so much gas so quik. O yes I forgot that I unplugged that injector wire connection and it still blows gas. It is so much gas engine hydrolocks after about 6 revolution , with the spark plug back in of course. Any help here would be great.
