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 dealing with a gas smell in your 2003 INFINITI G35, it's essential to adopt a systematic diagnostic approach to identify the underlying issue effectively. Start with the simplest solutions, such as checking the fuel cap; a loose or damaged cap can easily allow gas vapors to escape. Next, conduct a thorough visual inspection for any signs of fuel leaks around the fuel lines, injectors, or tank, as these are common culprits. If no obvious leaks are found, utilize an OBD-II scanner to check for any error codes that might indicate problems within the fuel system or emissions components. Pay particular attention to the evaporative emissions system, inspecting parts like the charcoal canister and purge valve for any signs of damage or leaks. Additionally, examine the exhaust system for any leaks that could be contributing to the gas smell. Finally, monitor your engine's performance; if it’s running too rich, it may also produce a gas-like odor. By following this structured approach, you can efficiently diagnose and address the source of the gas smell in your vehicle.
If your 2003 INFINITI G35 is emitting a gas smell, it's crucial to identify the underlying issue to ensure both safety and vehicle performance. One common culprit could be a fuel leak within the fuel system, which can occur due to worn hoses or damaged components. Additionally, a faulty fuel injector may not seal properly, leading to fuel escaping and creating a noticeable odor. Another potential source is the evaporative emissions system; if there's a leak in this system, it can allow gas vapors to escape into the cabin. Don't overlook the gas cap, as a loose or damaged cap can also contribute to the smell by failing to contain vapors. Lastly, issues with the exhaust system, such as leaks or a malfunctioning catalytic converter, can sometimes result in a gas-like odor inside the vehicle. Addressing these problems promptly is essential, and while some DIY fixes may be possible, consulting a professional mechanic is often the best course of action to ensure a thorough diagnosis and repair.
Addressing a gas smell in your 2003 INFINITI G35 is not just a matter of convenience; it is a critical safety concern that demands immediate attention. Gas leaks can lead to dangerous fire hazards, putting you and others at risk. Moreover, inhaling gas fumes can have serious health implications, including dizziness and nausea, which can escalate with prolonged exposure. Ignoring this issue could also result in further damage to your vehicle, leading to expensive repairs down the line. Therefore, it is essential to act swiftly when you detect a gas smell in your car, ensuring both your safety and the longevity of your vehicle.
