What happens when injector pump fails?

What Happens When A Diesel Injector Pump Fails? Poor fuel injection timing can cause low engine performance, engine misfires, excessive fuel consumption, and diminished power and cooling of engines. Engine stalling as a result of a failed injector normally occurs when the nozzles are badly blocked or when there’s a fuel leak where the injector connects with the fuel lines.

How do you diagnose a bad injector pump?

    The top reasons for fuel pump failure are contamination, overheating, and the gears in the the fuel pump wearing out over time. Rust, debris, and dirt are three common particles that can somehow enter the gas tank and be fed towards or through the intank fuel filter and possibly into the fuel pump.

    How do you test a diesel injector pump?

    Cummins recommends a simple visual test to start. First remove the valve cover, then crank the engine and let it idle. With a light, study the injector body of each cylinder. Sometimes, if the injector body is cracked externally, you may be able to notice a small wisp of smoke from the injector.

    How long do diesel injector pumps last?

    Diesel fuel injectors generally have a shorter lifespan than their predecessors, meaning they need to be replaced more frequently for optimal performance. The life expectancy of a good quality diesel fuel injector is around 150,000 kilometres. They should be checked out by a professional at around this time.

    Why is there no fuel coming out of my injectors?

    Again, if it’s the fuel pump (which it most likely is), it’s down to the inability of the fuel pump itself to hold the needed pressure to get the fuel from the tank to the injectors. The fuel pump may be repairable but in most cases you’ll want to change it with a new one, even if it can be “repaired”.

    What are the symptoms of a bad injector pump?

    This symptom can mean other things, but people most often mistake an injector pump failure with dirty gas. When it’s the fuel pump causing the trouble, it most often has to do with the lack of constant pressure. The fuel pump can’t maintain the needed pressure at all times, so you get moments of sputtering.

    How many miles can a car run with a bad injector pump?

    The car may run perfect for 10, 20 or even 50 miles, but it will have brief periods of sputtering or jerking (1-5 miles) before returning to its normal state. This symptom can mean other things, but people most often mistake an injector pump failure with dirty gas.

    What are the most common diesel fuel pump problems?

    The earliest diesel fuel pump problem is foretold by an engine sputter, particularly at a higher speed. This most often happens on highways or back roads with a slightly higher average speed. The car may run perfect for 10, 20 or even 50 miles, but it will have brief periods of sputtering or jerking (1-5 miles) before returning to its normal state.
