My boyfriend car, which is fuel injected keeps flooding out. Fuel pump, sensors, spark plugs, everything possible has been replaced without success. What is he missing? ---

You don’t say what engine he has, if it’s either of the 4.6’s Check the vacuum line to the “Fuel Pressure Regulator” There should NOT be any fuel in it, if there is fuel, it’s leaking and that’s where the fuel is coming from It will look like one of these ![1](https://global.discourse-cdn.com/cartalk/original/3X/6/5/650ab2b89e81a21294b9f2d498c7876da2d996c7.jpeg) ![2](https://global.discourse-cdn.com/cartalk/original/3X/c/9/c940647f74066cae6b71a4f0aac6d168193157c1.jpeg) ---

Good ideas above. Also ask your shop to verify the engine coolant temperature sensor that the engine computer uses is registering the correct coolant temperature. ---
