How Do I Know When My Fuel Pump is Going Bad?

Reader Question

About a year ago my car stalled and I had to replace the fuel pump.
Recently, my car has been showing similar signs of the same problem ( ie. not getting up to speed when I press down on pedal, not starting right away, feeling jerky while driving ) I was told back when I replaced the pump that it was because of keeping the gas levels too low for long periods of time.

Is that true? I will admit I may keep the levels a little on the lower side. To avoid having to replace the pump again, is there anything that I can do other than keeping my gas at a higher level? Or at least to keep it from getting worse? Is my pump doomed already?

Thanks

Hey there Rocky,

I do agree that driving a fuel injected vehicle low on fuel is not a good idea. There is water, dirt and sand found in the bottom of just about every fuel tank I have seen. This is some what normal to find, so allowing the electric fuel pump (which is located in the bottom of the fuel tank) to suck up this crud will only cause premature wear and tear to the pump itself.

Before you just jump to conclusion that you are in need of a new fuel pump I would have your mechanic check this out, especially the spark plug wires. Worn out spark plug wires can cause the engine to jerk, or misfire and also cause the other symptoms you are experiencing.

Blessings,
