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.

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 faced with a gas smell in your Nissan GT-R, start by inspecting the gas cap, as a loose or damaged cap is often the simplest and most common culprit. Ensure it is tightened securely and check for any signs of wear or cracks that could prevent a proper seal. If the gas cap appears to be in good condition, the next step is to examine the fuel system, particularly the fuel injectors and lines for any signs of leaks. A visual inspection can reveal wet spots or fuel stains that indicate a problem. Additionally, check the emissions control system, as malfunctioning components can also contribute to gas odors. If these initial checks do not resolve the issue, consider looking for loose hoses or other potential leaks in the engine compartment. Remember, while DIY troubleshooting can be effective, safety is paramount; if the smell persists or if you are uncertain about any findings, it is wise to consult a qualified mechanic for a comprehensive diagnosis and repair.
When you detect a gas smell in your Nissan GT-R, it’s crucial to investigate the underlying causes to ensure your safety and the vehicle's performance. One of the most common culprits is a loose or damaged gas cap, which can allow fuel vapors to escape, creating a noticeable odor. Additionally, issues within the fuel system, such as leaking fuel injectors or other fuel system leaks, can lead to a strong gasoline smell. It's also important to consider the emissions control system, as malfunctions here can contribute to the problem. A more serious concern could be a gas leak, which may indicate a poorly functioning engine or catalytic converter, necessitating immediate attention. Lastly, overfilling the gas tank can cause fuel to spill into the EVAP system or onto nearby components, resulting in unpleasant odors. By systematically checking these areas, DIY enthusiasts can identify and address the source of the gas smell, ensuring a safer driving experience.
Experiencing a gas smell in your Nissan GT-R is not just an inconvenience; it signals a potential safety hazard that requires immediate attention. Ignoring this issue could lead to severe consequences, including the risk of fire or significant engine damage. Start by checking the fuel cap to ensure it is securely fastened and in good condition, as a loose cap can often be the culprit. Next, inspect the area beneath your vehicle for any signs of fuel leaks, such as dark spots on the ground, which may indicate a more serious problem. Pay particular attention to the fuel pump and rubber supply lines, as these components can deteriorate over time and lead to leaks. Additionally, issues with the filler or breather tube can also contribute to the gas smell. If you suspect a leak, it is crucial to refrain from driving your vehicle and seek professional assistance to diagnose and resolve the issue. Regular maintenance checks and monitoring your fuel consumption can help prevent such problems from arising in the future, ensuring both your safety and the longevity of your GT-R.
