What would cause a fuel pump to continually go bad?

I own a Jeep Cherokee a four cylinder 1996 and the fuel pump keeps going bad the last one lasted a week. What could be causing this? I recently changed the injectors, 02 sensors, oil, and the pump has been changed a total of two times in the past 3 months. Please help me fastWhat would cause a fuel pump to continually go bad?well it depends on what goes wrong with it. like the person who answered before me if its a electrical surge then the wires could get fried. though if it just stops working with no electrical problems then you have kerosine built up in your gas tank. if your car sits too long the gas in it goes bad ( thanks alot oil companys, they put it in there so people dont hoard gas). if your pump sucks it in and clots up it obviously wont be able to suck any more gas threw it. either have your tank cleaned or keep it at at least 1/4 tank and only put in premium for at least the next few times you fill up

Check to see if you have a fuel pump relay and if you do, replace it.

If you only got a week out of a brand new pump, I'd get the wiring tested. make sure your not shorting out the unit. You'll need a mechanic to test cars wiring for proper voltage.



Good Luck
