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 1999 Mazda B2500, it's essential to adopt a systematic diagnostic approach to identify the root cause effectively. Start with a thorough visual inspection of the fuel system, looking for any signs of leaks around the fuel lines, injectors, and tank. A faulty fuel injector can often be the culprit, so pay attention to symptoms like poor fuel economy or rough idling, which may indicate injector issues. Additionally, check the integrity of the evaporative emissions system, as a malfunction here can lead to fuel vapors escaping. Don’t overlook the gas cap; ensure it is tightly sealed and in good condition, as a loose or damaged cap can easily cause a gas smell. Lastly, inspect the exhaust system for any leaks that might allow exhaust fumes to enter the cabin. If the check engine light is on, using an OBD-II scanner can provide valuable error codes to guide your diagnosis. If these steps do not reveal the source of the smell, consulting a qualified mechanic for a professional inspection may be necessary to ensure your vehicle is safe and functioning properly.
When you detect a gas smell in your 1999 Mazda B2500, it's crucial to identify the underlying causes to ensure your safety and the vehicle's proper functioning. One common issue could be a leaking fuel injector, which allows gas vapors to escape into the air. Additionally, faulty fuel lines, often characterized by cracks or damage, can lead to significant gas leaks, creating a strong odor. Another potential culprit is the gas cap; if it is loose, damaged, or missing, it can permit fuel vapors to escape. Furthermore, a leak in the fuel tank itself can produce a noticeable gas smell inside the vehicle. Lastly, problems with the Evaporative Emissions Control System (EVAP), such as a malfunctioning charcoal canister or purge valve, can also result in gas fumes entering the cabin. Addressing these issues promptly is essential not only for your vehicle's performance but also for your safety, as fuel leaks can pose serious hazards.
Addressing a gas smell in your 1999 Mazda B2500 is not just a matter of inconvenience; it is a pressing safety concern that requires immediate attention. Ignoring this issue can lead to severe consequences, including the risk of fire due to gasoline leaks, which can ignite from even the smallest spark. Additionally, the health risks associated with inhaling gasoline fumes are significant, as they can cause dizziness, headaches, and nausea, with prolonged exposure potentially leading to more serious health complications. Furthermore, gasoline leaks pose an environmental threat, as they can contaminate soil and water sources, leading to broader ecological damage. Therefore, it is essential to act swiftly and investigate the source of the gas smell to protect yourself, your vehicle, and the environment.
