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 2003 Ford Windstar, it's essential to adopt a systematic diagnostic approach to identify the underlying issue. Start with a thorough visual inspection of the fuel system, looking for any signs of leaks around the fuel lines, injectors, and tank. If you notice any fuel pooling or a strong odor near these components, it may indicate a fuel leak that requires immediate attention. Next, consider the condition of the fuel injectors; symptoms like poor fuel economy or rough idling can suggest they may be faulty. Additionally, inspect the evaporative emissions system, including the charcoal canister and fuel cap, as these can also contribute to gas odors if damaged or leaking. Don't overlook the exhaust system, as leaks in the exhaust pipes or muffler can allow gas fumes to enter the cabin. Lastly, ensure that your vehicle's ventilation system is functioning properly, as a clogged cabin air filter can trap odors inside. If the check engine light is illuminated, using an OBD-II scanner can provide valuable error codes to guide your diagnosis. By following this structured approach, you can effectively pinpoint the source of the gas smell and take the necessary steps to resolve the issue.
If you're detecting a gas smell in your 2003 Ford Windstar, it's crucial to investigate several common problems that could be at play. One of the first things to check is the gas cap; a loose or damaged cap can easily allow fuel vapors to escape, creating a noticeable odor. Additionally, inspect the fuel system for any leaks or malfunctions, as these can lead to fuel odors inside the vehicle. Another area to consider is the emissions control system, where issues such as a failing catalytic converter may not only produce unusual smells but could also trigger the check engine light. Lastly, examine the intake manifold running control relay for any broken plastic bushings, which can cause stalling and contribute to the gas smell. Addressing these issues promptly is essential for both safety and vehicle performance, and if you're uncertain about the diagnosis, seeking help from a qualified mechanic is advisable.
Addressing a gas smell in your 2003 Ford Windstar is not just a matter of convenience; it is an urgent safety concern that should not be overlooked. Ignoring this issue can lead to severe consequences, including the risk of fire, which poses a significant threat to you and your passengers. Additionally, the inhalation of gasoline fumes can result in serious health issues, such as dizziness and nausea, which can impair your ability to drive safely. Beyond personal safety, gasoline leaks can have detrimental effects on the environment, potentially contaminating soil and water sources. Therefore, if you detect a gas smell, it is imperative to take immediate action to diagnose and resolve the issue, ensuring both your safety and the well-being of those around you.
