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.

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. 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 dealing with a gas smell in your 1999 INFINITI G20, it's essential to adopt a systematic diagnostic approach to identify the underlying issue effectively. Start with a visual inspection of the vehicle, focusing on areas where fuel leaks are most likely to occur, such as under the vehicle, around the fuel tank, and near the engine. Pay particular attention to the fuel cap; ensure it is securely tightened and free from damage, as a faulty cap can allow fuel vapors to escape. Next, utilize an OBD-II scanner to check for any error codes that may indicate problems within the fuel system or emissions components. If no issues are found, inspect the evaporative emissions system, including the charcoal canister and purge valve, for any signs of wear or leaks. Finally, examine the exhaust system for any cracks or damaged gaskets that could contribute to the gas smell. By following this structured approach, you can efficiently diagnose and address the source of the gas odor, ensuring your vehicle remains safe and functional.
If your 1999 INFINITI G20 is emitting a gas smell, it’s crucial to identify the underlying cause to ensure both safety and vehicle performance. One common issue could be a leaking fuel injector, which can lead to fuel seeping into the engine compartment and creating a strong odor. Additionally, inspect the fuel lines for any signs of damage or wear, as cracks or leaks in these lines can also release fuel vapors. Another area to check is the gas cap; a loose or damaged cap can allow vapors to escape from the fuel tank, contributing to the smell. Furthermore, consider the possibility of a fuel tank leak, which can occur due to corrosion or physical damage. Lastly, problems with the evaporative emissions system may also be at play, as this system is designed to manage fuel vapors and can malfunction, leading to odors inside the vehicle. Addressing these issues promptly is essential, and while some repairs may be manageable for a DIY enthusiast, consulting a professional mechanic is advisable for more complex problems to ensure your vehicle remains safe and functional.
Addressing a gas smell in your 1999 INFINITI G20 is not just a matter of inconvenience; it is a pressing safety concern that requires immediate attention. Gas leaks can lead to catastrophic outcomes, including the risk of fire, which poses a significant threat to both your safety and the integrity of your vehicle. Moreover, the inhalation of gas fumes can have serious health implications, leading to symptoms such as dizziness, headaches, and nausea, which can impair your ability to drive safely. Additionally, neglecting this issue can result in further damage to your vehicle's components, potentially leading to expensive repairs down the line. Therefore, it is crucial to take any gas smell seriously and seek professional assistance as soon as possible to mitigate these risks and ensure your vehicle remains safe and reliable.
