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.
To effectively diagnose a gas smell in your 1999 Honda Prelude, start with a systematic approach that prioritizes simpler checks before moving on to more complex diagnostics. Begin by inspecting the area under your vehicle for any visible signs of gasoline leaks, such as dripping fuel or wet spots around the fuel tank and fuel lines. Next, ensure that the fuel cap is securely fastened, as a loose or damaged cap can easily allow gas odors to escape. Following this, examine the fuel lines for any cracks, holes, or loose connections, as these can be common culprits for gas leaks. Additionally, check the fuel injectors to confirm they are functioning correctly, since faulty injectors can lead to gas leakage. Don’t forget to inspect the fuel tank itself for any signs of damage or corrosion, which could also contribute to the smell. If, after these checks, the source of the gas smell remains elusive, it’s advisable to consult a mechanic for a comprehensive inspection. This methodical approach not only helps in identifying the issue but also ensures that you address the simplest problems first, potentially saving time and money.
If your 1999 Honda Prelude has developed a gas smell, it’s essential to investigate several common problems that could be the source. One of the first things to check is the gas cap; a loose or damaged cap can easily allow gasoline vapors to escape, leading to that unmistakable odor. If the cap appears secure, the next area to examine is the fuel system. A failing fuel pressure regulator can cause an excess of fuel, which may trigger the check engine light and contribute to the smell. Additionally, issues within the emissions control system, particularly a clogged evaporative emission control system (EVAP), can also result in gas odors. Other potential culprits include a malfunctioning fuel pump or a failing catalytic converter, both of which can lead to fuel leaks or improper combustion. By systematically inspecting these components, you can identify the root cause of the gas smell and take the necessary steps to resolve the issue, ensuring your vehicle runs safely and efficiently.
Addressing a gas smell in your 1999 Honda Prelude is not just a matter of convenience; it is an urgent safety concern that should not be overlooked. Gas leaks can create a serious fire hazard, putting you and others at risk. Additionally, inhaling gas fumes can lead to harmful health effects, including dizziness and nausea, which can impair your ability to drive safely. Beyond immediate safety and health risks, neglecting this issue can result in more extensive damage to your vehicle's fuel system, leading to costly repairs down the line. Therefore, it is essential to take any gas smell seriously and investigate the source promptly to ensure your safety and the longevity of your vehicle.
