3rd Fuel Pump Replacement in 4 months
I have a 2006 Chevrolet HHR with a 2.4L, and Automatic transmission, and 140,000 miles on the odometer. No trouble codes with BlueDriver scanner. I noticed that the car wouldn't always start right away every time I turned the key. I replaced the fuel pump with a Delphi from AutoZone. All was good and it started right up like normal. Two months later, I was sitting at a Drive-thru when I heard a Thunk from what I believe was the gas tank and within seconds my engine stalled. I could not get it to start. I had a friend tow me back home and found I had no fuel pressure. I took the new fuel pump out of the tank and I notice the bottom of the plastic pump was badly cracked. Swapped it out for another Delphi, and two months later today, I was back at having a hard time getting the car started. I bought a fuel pressure gauge and noticed that the pump will prime up to 60 psi, but as soon as the pump shuts off, the pressure drops to zero. The pump is noticeably louder too. I compared this to another 06 HHR that I own(yes I have two identical HHRs), and it does not do this. AutoZone said they would swap me out with the AC Delco pump at no extra charge. I am just worried that something else is wrong. I have researched this problem for several hours, but I can't find anyone with the same problem.
