Question: I Have Maruti Swift vdi(Disel) car,since 2-3 months we are facing engine dead issue while running,Maruti service center,they changed fuel pump two times, but the car still stalls on road.
Answers: Please check the following : ·It may be due to air lock present in the fuel feed lines or fuel vapor lock in a fuel tank. ·A very tiny leak in your fuel system will cause this. It sucks in air but does not leak fuel. Sometimes fuel filter housing can collect enough air. ·Else if the problem repeats, please check the electrical connections/sensors & the ECM via a Scanner. Injector nozzle, bad fuel, high pressure pump, please check the Nozzle output current.
