1998 petrol transit starts then stop again


Sounds like a fuel starvation issue. You may want to start with something simple like changing the fuel filter, and move on from there. After replacing the fuel filter, check fuel system pressure to ensure it's in the right range (around 47 PSI for most fuel injected gasoline (petrol) engines). If the fuel pressure is low, it may be the pre-filter on the fuel pump, or the fuel pump itself.

2000 Kia Sadona...Stops from time to time. Usually when coming to a stop or taking off. Replaced fuel pump. Sometimes difficult for engine to turn over. New battery. Once I moved electrical connector...


Sounds like a possible crankshaft position sensor. It is located behind the harmonic balancer, inside the timing cover. It sets by the timing belt, so if you have a loose timing belt it could hit the crank sensor or throw up pieces of itself onto the crank sensor. A bad crank sensor can mimic a fuel pump issue. 721c6cee-d9f3-4086-a166-f472fa0318af.gif

1983 Mercedes Benz 240D; engine does not stop when key is turned OFF.


Diesel car engines are shut off by an electrical switch on the fuel pump, called the 'stop solenoid'. If you can locate the fuel pump, try to find the single electrical wire to it and disconnect it while the engine is running. (Watch out for moving parts!). The engine should stop. If this is the case, try unscrewing and cleaning it in diesel. Failing that, a new one shouldn't be too expensive.

I have a 1999 TERRANO QD32ETI engine and the problem which the local agents and private mechanics cannot solve is that when it's on the highways the engine performs well; that is it accelerates perfectly. However, when the vehicle comes to a dead stop, and you go for a quick take off the engine cuts out; it restarts quickly; now,when you make a slow acceleration after stopping the engine does not stall, but this can be a dangerous situation when crossing traffic on the highway or moving off from the traffic lights. We checked the computer, fuel pump and the injectors; our opinions differ and somehow
we feel the problem may be the fuel pump. We would appreciate your comments. Our many thanks for your kind assistance. Thanks Tony.

Just changed fuel pump and now rough idle surges and when stopped at red light my check engine light comes on but goes off when i start moving again


Did you just do the pump or the whole module.If you just did the pump the hose at the fuel pump may not be adeqautely secure this can result in low fuel pressure. Just for giggles remove the vacuum hose at the fuel pressure regulator and see if it make a difference if it does redo the fuel pump,secure the fuel pump with new clamps (not those plastic ones)
