The check engine light will illuminate any time there is a failed EVAP system test. This will be indicated by the various on-board diagnostics trouble codes that are stored in the vehicle's memory. Also, in some models, there may be a popping sound accompanying the check engine light, as the leak detection pump continuously attempts to pressurize the fuel tank. The canister may also cause difficulty starting the engine, a rough idle, and poor fuel mileage.
When the fuel filter begins to clog, the engine suffers from fuel starvation. This will cause a significant reduction in power and may also cause a misfire. These conditions may be intermittent, or constant and worsen over time. As the issue progresses, the engine may being to stall immediately after starting, fail to start, hesitate under throttle, or stall at particular angles on hills.

A fuel tank leak may also cause difficulty starting the engine, a rough idle, and poor fuel mileage. When a fuel tank is simply corroded to the point of failure, the exterior tank condition rarely shows damage. The inside of the fuel tank will be rusted or corroded, and rust flakes or other debris may be floating in the fuel.
For most vehicles, the only symptom will be a check engine light or fuel tank filler cap light illuminating on the driver instrument cluster. This is to signal that there is an evaporative emissions (EVAP) leak. In some situations, the vehicle may take longer than normal to start, or, more rarely, the engine may not start at all. on-board diagnostic (OBD) trouble codes will refer to EVAP system failures such as a small or massive EVAP system leak. Lastly, the powertrain control module may notice a lean running condition, which could even lead to random and infrequent misfires.
When troubleshooting a gas smell in your GMC Safari, it's essential to adopt a systematic diagnostic approach. Start by inspecting the fuel and emission systems for any visible leaks, as these are often the primary culprits. Look under the vehicle and around the fuel tank, paying close attention to the fuel lines and filter for signs of leakage. If no leaks are apparent, consider checking the connections of quick-connect fuel fittings to ensure they are properly seated, as loose fittings can also lead to gas odors. Additionally, inspect the filler hose and vent lines for any damage that might contribute to the smell. If these initial checks do not reveal the source of the problem, it may be necessary to delve deeper into potential issues with the air/fuel ratio sensor or the electronic ignition module. Remember, addressing these issues promptly is crucial to prevent further damage to your engine. If you find yourself unable to pinpoint the cause or suspect a more complex problem, seeking assistance from a GM specialist can provide the thorough diagnosis needed to resolve the issue effectively. By following this structured approach, you can ensure a safer and more efficient troubleshooting process for your GMC Safari.
When you notice a gas smell in your GMC Safari, it's crucial to investigate the issue thoroughly, as it can pose serious safety risks. Common problems that could lead to this odor include worn seals and o-rings in the fuel system, which may develop leaks over time. Additionally, inspect the fuel lines and fuel filter for any signs of damage or wear, as these components are often culprits for gasoline escaping. If the smell becomes more pronounced after refueling, it could indicate a loose fuel cap or issues with the filler hose and vent lines. To effectively pinpoint the source of the gas smell, carefully check all quick-connect fuel fittings to ensure they are properly seated. By methodically examining these areas, you can identify the underlying cause of the gas odor and take appropriate action to resolve the issue, ensuring both your safety and the reliable operation of your vehicle.
If your GMC Safari emits a gas smell, it’s crucial to act swiftly to prevent hazardous situations and costly repairs. A gas odor can indicate a fuel leak, which poses a fire risk and can lead to engine damage if left unchecked. Start by ensuring that the gas cap is securely tightened, as a loose cap is a common culprit. Next, conduct a thorough inspection of the fuel system, looking for visible leaks in the fuel lines, filter, and connections. Pay special attention to the emissions control system, as malfunctions here can also contribute to gas odors. If the smell is strongest near the gas cap, focus your efforts in that area, as hidden leaks may not be immediately visible. Additionally, verify the condition of the fuel pump, as issues here can lead to rough idling and gas smells. Always exercise caution when inspecting for leaks; ensure the engine is running to pressurize the fuel lines, and wear protective eyewear to safeguard against potential accidents. By addressing these concerns promptly, you can maintain the safety and reliability of your GMC Safari while avoiding more significant issues down the road.
