OK, we have a 1999 Ford Explorer 4.0 SOHC, its seems to be flooding it self out. Have replaced the coil pack, spark plugs, wires, fuel preassure regulator, sensors, ect. It sits there and cranks over, but wont start. Real strong gas smell. When we take the plugs out, they are wet, really bad. Before we where getting miss fire codes. So, we are now out of ideas. Can get it to run on either, when we shut off the fuel pump, but once we turn it back on it floods. HELP!!!!!!!!
