Common symptoms

• Problems in the injection pump VP 44

  When dealing with problems related to the VP 44 injection pump, it is important to recognize common symptoms that may indicate a possible failure of this crucial component. One of the most worrisome symptoms is when the vehicle suddenly stops in full operation. This situation can be frustrating and potentially dangerous, especially if it occurs in traffic. Another symptom is when the vehicle does not start after being parked. It can be disconcerting to find yourself in a situation where the vehicle simply refuses to start after being parked for a short period of time. In addition, some drivers have experienced the vehicle stalling on warm-up, which may indicate a VP 44 injection pump failure. Finally, another symptom of potential pump problems is a lack of injection pressure, which can manifest itself in a loss of power or difficulty accelerating properly.

• Symptoms VP44 Pump Failure, Electronic Failure and Mechanical Failure (Advance)

  In this guide, we are going to see how we can diagnose a VP44 pump, either electrical part (electronic module) or mechanical failure (advance), failures in this type of injection pump are very common, and more taking into account the years that usually have the vehicles that carry this pump mounted, come on, it is a matter of time that some part of the pump fails, either electronic or mechanical.

• VP44 Pump Failure Symptoms: Electrical Part (Electronic Module)

  Let’s go with the most common failure symptoms or failures of the electrical part of the VP44 pump, we are going to see the failure symptoms, from the most common to the less common ones:

  1. Fault 1: The car is in motion, driving and stops suddenly
     • If you start the engine, it does not start, diesel oil comes out of the injectors without pressure.

  1. Fault 2: The car starts and runs fine when cold, once warm the engine stops or jerks, once it cools down again it starts and runs fine.
     • In cold it goes all right, in some cases if the pump cools down with water it starts before, once warm again it jerks or stops, usually if with these symptoms it does not throw white smoke.

  In both cases, they are problems of the electrical part of the VP44 pump, additionally we can see the most common fault codes by brand (see below), to be on the safe side, the ideal is to connect a diagnosis and see what faults are present, we can also check the fuse and the wiring that reaches the pump connector (to be on the safe side) once this is ruled out, we can almost ensure 100% that the failure is in the electrical part of the pump.

• VP44 Pump Failure Symptoms: Mechanical Part (Advance)

  The failures that the VP44 pump gives us in the mechanical part or advance of the pump are different, and the most common are the following:

  1. Fault 1: You park the car and after a few hours (or the next morning) it does not start or it is very difficult to start, if you manage to start it, it makes a lot of white smoke.
     • This failure is due to the loss of diesel oil, we may not visibly see any loss, but if it loses pressure and air enters the fittings it will be difficult to start and it will not generate enough pressure to start.
  2. Fault 2: The car starts but it sounds very loud, as if the connecting rod is biting.
     • This problem is directly related to the pump advance, i.e. it is injecting out of point, since due to mechanical failure it does not adjust the mechanical advance.
  3. Failure 3: Loss of power, this, like the advance failure, is related to the mechanical part of the pump, which either does not inject enough or does it out of point, causing a loss of power.

  1. Fault 4: Visible diesel leakage, in many cases the car is running well, which leaks diesel.
     • This failure is very common, and we can see it visibly, the solution? disassemble the pump, replace the O-rings, adjust it and check it on the test bench

  As we can see, diagnosing a mechanical failure in a VP44 pump can be complex, the ideal is to connect a diagnostic machine and see what fault codes we are getting, in some cases there are problems in the fuel supply, so it is good practice to check this before disassembling the pump.
