All car gurus,
I like to ask what is usually causing a car's fuel pump to fail? How to prevent it from spoiling? My car is a Wira 1300CC, which engine failed to start due to fuel pump failure for 2 times already. The fuel pump costs me RM300++, which is a big deal to me. Appreciate advice from you guys. |

QUOTE(the_catacombs @ Apr 14 2009, 12:34 AM) ur car is fuel injection or carburetor??... efi n carb using different kinda fuel pump... carburetor (ac pump) doesnt fail often, unless leaking... efi ones however could fail as its electric fuel pump.... My Wira's engine is of fuel injection type.da fuel pump u changed is brand new or recond set??... how long u used it before failing??..  The original one that comes with the car lasted for about 5 years, then failed out of a sudden. A new one is replaced at a mechanic shop last year, then after about one year this fuel pump fails again few weeks ago. Now this is the third fuel pump at my car. The fuel pump given by the mechanics should be brand new, unless they wanted to cheat me. This post has been edited by TYK: Apr 14 2009, 12:50 AM |

QUOTE(the_catacombs @ Apr 14 2009, 01:05 AM) okla... assume the fuel pump is brand new, i suspect wiring to the fuel pump got problem... unstable voltage or something... I actually asked the latest mechanic I sent my car to few weeks ago, he said if the installation of the fuel pump is not right, like you said wiring problem or something like that, it won't last for 1 month. there is possibility dat the fuel pump is not brand new... and check if the fuel pump is oem item from proton and not some cheapskate fuel pump... I also didn't asked them about the fuel pump manufacturer. Should have asked them anyway. |

QUOTE(779364 @ Apr 14 2009, 09:31 AM) I will recommend you get the Taiwan OEM one.To prevent fuel pump from premature failing,do not fill up your car when its about to get empty and the fuel signal flashes.Also do not overfill the petrol tank.Only fill up slightly above the half mark.I will always do that and my proton's fuel pump is okay(touch wood). Oh, I always fill up my fuel tank only when it is almost empty and refill until around the full mark, but not overfilling though.Guess I should change my habit now. |

QUOTE(radioactive @ Apr 14 2009, 10:38 AM) almost empty? warning signal or sometime after warning comes on? Just before warning signal, when I saw warning signal, I will straight go to refill.sometimes fuel pump failure can be caused by empty tank, some users drive beyond the warning mark and as a result the fuel pump has to work extra hard to supply a steady supply, and also possibly without the fuel to take away the heat from the pump, it could overheat I guess from all the replies here, filling the tank when it is almost empty should best be avoided to prolong the fuel pump's life. But about the sudden failure of the fuel pump after one year, could be due to bad installation or something. This post has been edited by TYK: Apr 14 2009, 10:46 AM |
