Fuel Pump Check Valve Not Working at Claudia Eric blog

Fuel Pump Check Valve Not Working. Some pumps are sealed and cannot be. A bad check valve can cause fuel to boil in the fuel rail after shutdown, leading to a rough running engine when cold. If that happens while the engine is cold, the starter will crank a bit longer while the fuel pump builds enough pressure to start the engine. A fuel pump that’s not working properly may not be able to deliver enough fuel to the engine, which can cause a loss of power. If your vehicle is losing power under stress, such as when accelerating or climbing a hill, it could be a sign of a faulty fuel pump. I had the privilege of visiting airtex, and while i was there i spoke with shane neuman about. If no fuel, or only a dribble, emerges, either there is a blockage or leak somewhere in the fuel line (see checking fuel pipes) or the fuel pump is not working. I show testing ot see if the fuel pump check valve has failed causing a extended cranking time. If the check valve fails or is jammed open by fuel contamination, the hold pressure will leak down.
