What is the fuel pump issue on a 2017 Silverado?

The main problem reported with the 2017 Chevrolet Silverado is failure of the in-tank fuel pump module, which can lead to stalling, hard starting, or an engine that won’t start at all.

Chevrolet Silverado models from 2017 rely on an electric, in-tank fuel-pump assembly to feed the engine. When the pump or its sending unit wears out, becomes clogged, or experiences electrical faults, drivers may encounter extended crank times, intermittent starting, loss of power under load, or sudden engine stall. While not every vehicle is affected, owners have reported these symptoms and there are ongoing investigations, recalls, and service advisories related to the fuel system for this era. This article outlines what to look for, why it happens, and how to respond.

Symptoms that signal a fuel pump problem

Owners should watch for a cluster of warning signs that commonly accompany a failing fuel pump in the Silverado lineup.

• Engine stalls while driving or immediately after starting, sometimes with no warning


• Extended crank time or the engine cranks but does not start


• Intermittent loss of power or hesitation during acceleration


• Fuel pressure or fuel gauge readings behaving abnormally


• Unusual noises from the fuel tank area or fuel pump area when the ignition is on

Recognizing these symptoms early can help prevent stranded situations and reduce the risk of secondary damage to the fuel system or engine.

Causes and contributing factors

Several factors can contribute to a failed or failing fuel pump in the 2017 Silverado, beyond normal wear.

• Worn or failing in-tank fuel pump module and sending unit


• Clogged or contaminated fuel pickup screen and fuel filter


• Electrical issues, including faulty fuel pump relay, wiring, or grounds


• Overheating of the pump from high fuel temperatures or running fuel close to empty frequently


• Sediment or debris in the fuel tank, which can foul the pump or lines


• Manufacturing variances or service bulletin changes that affect certain production periods

These factors can act alone or in combination, and not all Silverado owners will experience every issue. Individual results vary by vehicle history, fuel quality, driving conditions, and maintenance.

Diagnosis and repair options

Professional diagnosis typically centers on verifying fuel delivery and electrical integrity to the pump system.

1. Obtain live data and scan for diagnostic trouble codes related to the fuel system and sensors.


2. Measure fuel pressure at the rail or port with a proper gauge to confirm low or inconsistent pressure.


3. Inspect the fuel pump relay, wiring harness, and grounds for corrosion, damage, or loose connections.


4. Check the in-tank fuel pump module and sending unit for signs of wear or debris; replace if necessary.


5. Replace the fuel filter if it is clogged or has not been serviced according to the maintenance schedule.


6. Test for proper electrical supply to the pump after repairs; re-test fuel pressure and engine performance.


7. Consider associated components such as the fuel pump driver module if testing suggests an electronic control issue.


8. Verify whether there are active recalls or service bulletins affecting your VIN and address any covered repairs at an authorized GM dealer.

In the repair decision, many technicians will start with a fuel-pressure test and a wiring/relay inspection, then move to pump replacement if the evidence points to a failing module or sending unit. After repairs, recheck fuel pressure and test drive to confirm the issue is resolved.

Recalls, service bulletins and how to check your VIN

GM and regulatory agencies have issued recalls and service notices related to fuel systems for trucks in this generation. Owners should verify recall status using their vehicle identification number (VIN) and consult with a Chevrolet dealer for any required remedies.

• Check official recall databases (such as NHTSA) by entering your VIN to see if a fuel-pump-related recall or bulletin applies to your Silverado.


• Consult the dealer for any open service actions and schedule needed repairs under the recall if applicable.


• Ask the service advisor about any relevant Technical Service Bulletins (TSBs) that address fuel-pump performance and related electrical concerns for your exact model year and engine.

Even if there is no active recall for your VIN, it remains prudent to monitor for symptoms and have a trusted shop inspect the fuel-pump system if you experience stalling, hard starting, or poor running. Service bulletins can cover procedures or parts improvements that are not part of a recall but can inform proper repair.

Preventive tips to extend fuel-pump life

Proper maintenance and driving practices can help reduce the risk of premature fuel-pump failure and prolong system reliability.

• Avoid routinely running vehicles with very low fuel levels; keep the tank above a quarter full when possible to prevent drawing sediment and to reduce pump overheating risk.


• Follow the manufacturer’s maintenance schedule for fuel-system components, including filters, where applicable.


• Use high-quality fuel and keep up with fuel-system cleaning if recommended by your dealer or mechanic.


• Address any electrical issues promptly; resolve wiring or relay problems that could cause intermittent pump operation.


• During diagnosis, ensure the pump is properly grounded and all harness connections are secure to avoid voltage drops.

Adopting these practices can help maintain fuel-system health and reduce the likelihood of future pump-related failures.

Takeaway

For 2017 Silverado owners, fuel pump issues most commonly present as stalling, hard starting, or intermittent loss of power, often tied to the in-tank pump module, its sending unit, or related electrical components. Diagnosis usually involves confirming fuel pressure, inspecting wiring and relays, and, if needed, replacing the pump module or associated parts. Checking for recalls and service bulletins via the VIN is essential, as some trucks in this era have had recall-related remedies. If symptoms appear, consult a qualified mechanic or Chevrolet dealer promptly to avoid being stranded and to secure proper repair.

In summary, the 2017 Silverado fuel-pump problem centers on the reliability of the in-tank module, with symptoms that mirror fuel delivery issues across modern direct-injection engines. Timely diagnosis and adherence to recall/service information can help owners navigate the issue effectively.
