Is Your Buick Regal's Fuel Pump Failing?
A failing fuel pump can cause a range of problems, from annoying to dangerous. If your Regal is showing signs of fuel starvation, the in-tank fuel pump module is a likely suspect. Ignoring the symptoms can leave you stranded.
Symptoms of a Bad Fuel Pump Module
- Engine Sputtering: The engine may sputter or surge at high speeds, as if it's running out of gas.
- Difficulty Starting: A weak pump may struggle to build enough pressure to start the engine, leading to long crank times.
- Stalling: The engine may stall unexpectedly, especially under load or when warm. This is a serious safety issue.
- Loss of Power: You may notice poor acceleration and a general lack of power.
- Check Engine Light: Fuel pressure issues can trigger diagnostic trouble codes. 🎬 Watch: A breakdown of common bad fuel pump symptoms
Known Issue: 2011 Buick Regal 2.4L High-Pressure Fuel Pump
For the 2011 model year with the 2.4L engine, GM issued a special coverage bulletin (TSB 12313) for the high-pressure fuel pump (HPFP), which is a separate part from the in-tank module. Symptoms included a rough running engine, stalling, and a P0172 trouble code. The TSB covered the replacement of the HPFP and the engine balance chain. 🎬 See how to diagnose P0172 codes and rough running issues While this special coverage has likely expired for most vehicles, it's important to correctly diagnose whether your issue is with the in-tank pump or the engine-mounted HPFP.
Choosing the Right Aftermarket Fuel Pump
When replacing your fuel pump module, you have a choice between OEM and aftermarket parts. For a critical component like this, quality matters.
Brand Tiers for Your Regal
- Tier 1: OEM Supplier (Delphi): Delphi was the original parts division for General Motors. Choosing a Delphi fuel pump is often the same as buying the genuine GM part, just in a different box. For fitment and reliability on your Regal, Delphi is a trusted choice that mechanics recommend.
- Tier 2: Reputable Aftermarket (URO Parts and others): Brands like URO Parts fall into a broad category of aftermarket manufacturers. While some may offer good value, there is very little search-verified information or long-term owner feedback available for URO Parts fuel pumps specifically for the Buick Regal. This lack of a track record can be a risk.
- Tier 3: Economy Brands: Low-cost, unknown brands are a gamble. They often have issues with fitment, incorrect fuel level readings, and premature failure. The money saved upfront is often lost when you have to do the job a second time.
Pro Tip: Given that replacing the fuel pump requires significant labor, it's wise to invest in a quality part. An OEM-supplier brand like Delphi provides peace of mind and is less likely to fail prematurely.

|---|---|
| New OEM (GM Genuine) | $450 - $700 |
| New Aftermarket (Delphi, URO Parts) | $206 - $675 |
| Shop Labor | $200 - $350 |
Frequently Asked Questions
Is there a recall on the 2011-2017 Buick Regal fuel pump?
No, there are no specific recalls for the in-tank fuel pump module assembly on the 2011-2017 Buick Regal. There was a Special Coverage (TSB 12313) for the separate high-pressure fuel pump on 2011 models with the 2.4L engine, but this was not a formal safety recall.
Can I replace the fuel pump myself?
Yes, for a mechanically inclined person, this is a feasible DIY job. The pump is accessed through a panel under the rear seat, so you do not have to drop the entire fuel tank. 🎬 Watch: Step-by-step guide to removing and installing the fuel pump However, you are working with gasoline, which is dangerous. You must take proper safety precautions, including disconnecting the battery and working in a well-ventilated area.
Should I replace the whole module or just the pump motor?
It is strongly recommended to replace the entire module assembly. The assembly includes the pump, sending unit (for the fuel gauge), strainer, and reservoir. These components are designed to work together. Trying to replace just the motor can lead to compatibility issues and is generally not worth the small cost savings.
What is the difference between the in-tank pump and the high-pressure fuel pump?
The in-tank fuel pump module is a low-pressure pump that moves gas from the tank to the engine. On direct-injection engines like those in the Regal, a second, engine-mounted high-pressure fuel pump (HPFP) boosts the fuel pressure significantly. The TSB for the 2011 Regal 2.4L specifically concerned the HPFP, not the in-tank pump.
