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 diagnosing a gas smell in your 2000 GMC Safari, it's essential to adopt a systematic approach that prioritizes safety and efficiency. Start by checking for fuel leaks, as these are often the most straightforward issues to identify. Inspect the fuel lines, tank, and injectors for any visible signs of leakage. Next, focus on the fuel injector O-rings; worn or damaged O-rings can lead to fuel escaping and should be examined closely. Following this, assess the fuel filter, as a clogged filter may cause fuel to spill, contributing to the odor. Don’t overlook the EVAP system, which plays a crucial role in containing fuel vapors; any malfunction here can lead to noticeable gas smells. Additionally, ensure that your fuel cap is secure and undamaged, as a loose or faulty cap can allow vapors to escape. Lastly, inspect the exhaust system for leaks, particularly near the fuel tank, as these can also introduce gas fumes into the cabin. By methodically checking these components, you can effectively pinpoint the source of the gas smell and take the necessary steps to resolve the issue. Always remember to prioritize safety when working with fuel systems and consider consulting a professional if the problem persists.
When you detect a gas smell in your 2000 GMC Safari, it's crucial to investigate the issue promptly, as it can indicate serious problems. One of the most common culprits is a leaking fuel injector, which can emit gas vapors into the air, creating a noticeable odor. Additionally, inspect the fuel lines for any cracks or damage, as these can lead to leaks and a strong gasoline smell. Don't overlook the gas cap; if it's loose, damaged, or missing, it can allow fuel vapors to escape, contributing to the odor. Another potential source is the Evaporative Emissions Control System (EVAP), which can malfunction and cause gas fumes to leak into the vehicle. Lastly, check for any leaks in the fuel tank itself, as this can also be a significant source of the gas smell. Addressing these issues not only enhances your vehicle's performance but also ensures your safety on the road.
Addressing a gas smell in your 2000 GMC Safari is not just a matter of convenience; it is a pressing safety concern that requires immediate action. The presence of gas fumes can indicate a leak, which poses a significant fire hazard that could endanger both you and your vehicle. Additionally, inhaling gasoline vapors can lead to serious health issues, including dizziness, headaches, and nausea, making it imperative to resolve the issue swiftly. Furthermore, neglecting this warning sign can result in more extensive damage to your vehicle's fuel system, leading to costly repairs down the line. Therefore, if you detect a gas smell, it is crucial to investigate the source and address it without delay to ensure your safety and the longevity of your vehicle.
