2008 HHR Fuel Pump Replacement: Complete Guide to Symptoms, Diagnosis, and Cost
The bottom line: If you own a 2008 Chevrolet HHR and you are experiencing hard starting, engine sputtering, loss of power, or a whining noise coming from the fuel tank, the fuel pump is very likely the culprit. Replacing the fuel pump on a 2008 HHR typically costs between $200 and $600 for parts and labor at an independent shop, with dealer pricing running 20-40% higher. Most fuel system failures on this vehicle cluster between 103,000 and 170,000 miles, with the median around 125,000 miles. This guide walks you through everything you need to know about diagnosing, replacing, and choosing the right fuel pump for your HHR.
How Serious Is the Fuel Pump Problem on the 2008 HHR?
The 2008 Chevrolet HHR has a documented fuel system issue, but it is not catastrophic. According to NHTSA owner complaints, 14 complaints have been filed regarding fuel system problems on this vehicle. Repairs average around $1,200 when the issue involves fuel line replacement or fuel tank leaks, and most owners catch the problem before it causes a complete breakdown.
One important note: there are currently no active recalls covering fuel system issues on the 2008 HHR. The complaints filed represent owner-reported failures that have not risen to the level of a manufacturer-issued recall, but they are still worth knowing about before you buy or budget for repairs.
Symptoms of a Failing Fuel Pump on Your 2008 HHR
A bad fuel pump will make your car crank but not start. If your HHR won't start, the fuel pump could be faulty, and you will need to replace it. Here are the most common warning signs to watch for:
1. Weird Sounds
A whining noise coming from the fuel tank can indicate a fuel pump failure. Backfires and sputtering engines can also suggest a malfunctioning fuel pump. Any pinging or knocking sound from your car is never good, so always pay attention. Note that any sound issues may trigger the Check Engine Light on the dashboard.
2. Diminished Engine Performance
There could be a loss of power if your car's fuel pump cannot provide the engine with sufficient fuel. High or low fuel pressure due to a faulty fuel pressure regulator may cause surging or sputtering. A less noticeable fuel pump problem can be a decrease in fuel efficiency.
3. Difficulty Starting
If the fuel pump assembly can no longer supply the required fuel to the engine, your car will experience starting difficulties. Start-up may take a few seconds longer than usual, or you will need a few attempts to get the engine cranked. Ignore the issue, and eventually, your car simply won't start.
4. Misfiring
Many things can cause misfiring, including a malfunctioning fuel pump. If the engine isn't getting adequate fuel, it won't have the proper air-fuel ratio in the combustion chamber, leading to inefficient combustion and misfires.
5. Engine Overheating and Stalling
A faulty fuel pump can overheat. If you have an overheating fuel pump issue, the vehicle might run for 15-30 minutes before overheating and stalling. After letting your engine cool, it will run again, only to halt as the issue repeats.
6. Fuel Leaks
Owners have reported fuel odor inside and outside the vehicle, visible fuel leaks or puddles under the rear driver's side wheel well area, and wet spots on pavement or ground beneath the vehicle. These can stem from fuel line issues, fuel pump corrosion, or fuel tank leaks.
Diagnosing the Fuel Pump: Testing Fuel Pressure
Before you replace the fuel pump, it is wise to confirm it is actually the problem. You can do this with a fuel pressure test gauge, which is available to buy or borrow from most auto parts stores. This will allow you to check the fuel pump to see if it is working correctly.
Here is how to test fuel pressure on a 2008 HHR:
- Put the key in the "off" position and check the pressure, which should not be zero.
- Turn the key to the "on" position and check the pressure, which should be around 20 psi.
- Turn the key to the "run" position, and the pressure should be approximately 58 psi.
- Turn the key back to the "on" position and check the pressure again. If it drops by more than 5 psi in one minute, you likely need to replace the fuel pump.
The fuel pressure gauge should register 50-60 PSI if the fuel pump is working correctly. When you turn the key to the "on" position, you should see the fuel pressure gauge register around 20 PSI. Turning the key to the "run" position should result in a pressure reading of approximately 50-60 PSI.
If the fuel pressure gauge registers significantly less than 50 PSI, it may indicate a problem with the fuel pump or a leak in the fuel system. The fuel pressure should not drop more than 8 PSI in 5 minutes. If the pressure drops too quickly, it could be a sign of a faulty fuel pump or a leak.
What to Know About the 2008 HHR Fuel System
The 2008 Chevrolet HHR has a few specific fuel system quirks that owners should be aware of:
Fuel Line Failure. Owners have reported fuel line issues at 103,000 to 178,000 miles, with one early failure at 6,000 miles. Symptoms include fuel odor, visible fuel leaks, and pulsating fuel flow from a compromised fuel line. Repairs require fuel line replacement.
Fuel Pump Corrosion. The fuel pump assembly can become severely corroded, resulting in fuel leakage from the pump area and contamination of the fuel system. This typically occurs at approximately 125,000 miles. Owners report fuel leaks from the pump area and fuel on the ground underneath the vehicle, requiring fuel pump replacement.
Fuel Tank Leak. In rare cases, fuel leaks from the fuel tank itself, not stemming from line connections or pump corrosion. One owner reported this at approximately 6,000 miles. Fuel tank replacement was performed, but the failure persisted after replacement, suggesting a possible secondary issue.
How Much Does a 2008 HHR Fuel Pump Replacement Cost?
A fuel pump replacement cost can be between $200 and $600, including labor. However, this cost can go up further depending on the additional parts that need to be replaced. Independent shops typically charge around $1,200 for more extensive fuel system repairs on this vehicle, and dealer pricing tends to run 20-40% higher.
Here are the estimated costs for some related parts:
- Fuel tank hose: $20-$40
- Fuel filter: $85-$100
- Fuel pressure regulator: $160-$195
- Fuel injector: $600-$1,200
- Fuel level sending unit: $1,100-$1,300
If you are outside the factory warranty, an extended service contract often covers this category.
How Urgent Is a Fuel Pump Replacement?
Driving a car with a fuel pump problem can result in all of the bad fuel pump symptoms listed above, including your car running intermittently or not starting at all. That is why you should get your car's fuel pump replacement and maintenance scheduled as soon as possible.
It is important to note that driving with a bad fuel pump can be dangerous and may damage your engine or start a fire. If your fuel pump is bad, it is best to have your vehicle towed to a mechanic and get a new fuel pump installed.
