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 addressing a gas smell in your 2014 Volvo S80, it's essential to adopt a systematic diagnostic approach. Start with a thorough visual inspection of the fuel system, looking for any signs of leaks such as damaged fuel lines or rusted components. This initial step can often reveal obvious issues that are easy to fix. If no leaks are visible, consider the possibility of incomplete combustion, which may manifest as a gas smell from the tailpipe or inside the cabin, often accompanied by performance issues like sluggish acceleration. In this case, checking the fuel injectors is crucial, as a faulty injector can lead to fuel not being burned properly, resulting in a noticeable odor. If these steps do not identify the problem, utilizing diagnostic tools to read fault codes can provide deeper insights into the vehicle's systems, helping to pinpoint the source of the gas smell.
