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 faced with a gas smell in your Chevrolet Caprice, it's essential to adopt a systematic diagnostic approach to identify and resolve the issue efficiently. Begin by checking the gas cap, as a loose or damaged cap is often the simplest and most common culprit behind gasoline odors. Ensure it is securely tightened or replace it if necessary. If the smell persists, inspect the fuel system for leaks in the fuel lines or tank, as these can lead to significant safety hazards. Look for any visible signs of gasoline pooling under the vehicle. Next, consider the exhaust system; a leak in this area can also contribute to gas-like smells, so examine the muffler and exhaust pipes for any damage. If you suspect a more complex issue, such as a faulty fuel pressure regulator, monitor for symptoms like rough engine performance or strong odors inside the cabin. Lastly, don't overlook other potential sources, such as engine oil or coolant leaks, which can also emit similar smells. By following this methodical approach, you can effectively diagnose and address the source of the gas smell, ensuring a safer driving experience in your Caprice.

Inspect the gas cap for any signs of damage or improper sealing, as a simple fix may resolve the issue. Additionally, check for leaks in the fuel system, including the fuel tank, fuel pump, and fuel filter, as these components can develop cracks or loose connections over time, leading to noticeable gas odors. If the smell intensifies during specific driving conditions, it may indicate problems with the fuel pressure regulator, which can affect fuel delivery and pressure. Ignoring a gas smell can pose serious risks, including fire hazards and exposure to toxic fumes, so it’s essential to address these issues promptly. By conducting a thorough inspection and making necessary repairs, you can eliminate the gas smell and maintain the safety and functionality of your Chevrolet Caprice.
If your Chevrolet Caprice emits a gas smell, it’s crucial to act swiftly, as neglecting this issue can lead to serious safety hazards, including fire risks and exposure to toxic fumes. Start by checking the gas cap; a loose or damaged cap is often the simplest culprit behind fuel odors.
