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.

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 you detect a gas smell in your 2003 Mitsubishi Montero Sport, it's crucial to approach the situation methodically to ensure safety and effective resolution. Start by checking for visible leaks in the fuel lines, fuel tank, and injectors, as these are common culprits for fuel odors. Next, inspect the fuel cap to confirm it is securely tightened; a loose cap can allow fuel vapors to escape. If these initial checks do not reveal the source of the smell, examine the fuel filter for clogs or malfunctions, as these can disrupt fuel flow and contribute to odors. Additionally, consider the fuel injection system, as faulty injectors or pressure regulators may also be at fault. Lastly, don't overlook the evaporative emissions control system, which is designed to contain fuel vapors; any issues here can lead to noticeable gas smells inside the vehicle. If you are unable to identify the problem after these steps, consulting a qualified mechanic is advisable for a thorough inspection and accurate diagnosis. By following this structured approach, you can effectively troubleshoot the gas smell issue and maintain the safety and performance of your vehicle.
If you're detecting a gas smell in your 2003 Mitsubishi Montero Sport, it's crucial to identify the underlying cause to ensure both safety and vehicle performance. One of the most common culprits is a fuel leak, which can occur from damaged fuel lines, injectors, or even the fuel tank itself. This type of leak not only poses a fire hazard but can also lead to decreased fuel efficiency. Another potential issue could be a faulty fuel injector, which may allow fuel to escape into the engine compartment, creating a noticeable odor. Additionally, a loose or damaged gas cap can be an easy fix; if it’s not sealing properly, fuel vapors can escape, leading to a gas smell around the vehicle. Problems with the evaporative emissions system, such as a malfunctioning charcoal canister or purge valve, can also result in gas fumes escaping into the atmosphere. Lastly, don’t overlook the possibility of an exhaust system leak, which can sometimes mimic a gas smell inside the cabin. Addressing these issues promptly is essential, and while some may be manageable for a DIY enthusiast, others may require professional assistance to ensure a thorough and safe repair.
Addressing a gas smell in your 2003 Mitsubishi Montero Sport is not just a matter of inconvenience; it is a pressing safety concern that should be treated with urgency.
