PROBLEM: FUEL PUMP GETTING PROGRESSIVELY NOISIER IN SHORT PERIOD OF TIME
- I’m sadly familiar with the sound of a fuel pump going bad. My previous car, a 1987 Olds Cierra, went through three of them in the 20 years / 160k miles I had that car.
- I NEVER run the gas tank below 1/4 full; in fact, I fill up at the half tank mark 99% of the time.
- I have only ever run regular gas, NEVER E85, despite the flex fuel engine.
- This 2007 Impala has a history of both major and minor components failing early; i.e. power steering pump, water pump, OnStar battery, antenna and remote fob control, etc.
- Car has had all manufacturer recommended proactive maintenance done at proper mileage.
- Have read that GM and Chevy trucks of recent years have had a history of problem fuel pumps but am not finding any particular information indicating that Chevy or other GM cars are having fuel pumps fail early.
- Most of my driving has been and is short distances with multiple stops and restarts of the engine. Example, frequently run a route of about 10 miles with 4 to 6 stops at various places (grocery, pharmacy, vet, etc.) However, I do make a point of taking the car for a longer run of 20+ miles, including highway speeds, at least every two weeks.
- Do fuel pumps typically fail earlier with the type of short distance / frequent stops and restarts driving I do? Are my driving habits leading to early failure of fuel pumps?
- Do fuel pumps typically last longer than 7 years / 52,000 miles?
- Should I view this noisy and presumably failing fuel pump at this age/mileage as normal wear and tear or is this happening early enough in age/mileage to be worrisome?
