What You'll Learn
Check the gas tank cover opening lever
If you are having trouble opening the gas tank of your Mazda CX-9, it could be due to an issue with the gas tank cover opening lever. Here are some detailed steps to check and address this issue:
Locating the Lever
The first step is to locate the fuel release lever, which is typically found near the bottom of the driver's seat, close to the driver's side door. Look for a small lever with an image or symbol of a gas pump on it. In some newer car models, there might be a fuel release button instead of a lever, so check for that as well.
Checking the Lever
Once you have located the lever or button, try to engage it by pulling the lever up or pressing the button. You should hear a small "thunk" sound, indicating that the gas tank door has been unlocked. If you don't hear this sound or the door doesn't open, the lever or cable attached to it might be broken.
Accessing the Lever Mechanism
If you suspect a problem with the lever mechanism, you may need to access it for further inspection. Open the trunk of your car and locate the access panel closest to the fuel tank. Remove this panel to expose the locking mechanism for the gas tank door. If your car doesn't have an access panel, you may need to remove the cloth lining or interior panel near the inside of the fuel tank to access the mechanism.
Troubleshooting
With the mechanism exposed, you can inspect the lever, cable, and fuel door release actuator for any signs of damage or malfunction. The cable attached to the lever should be connected to the fuel door release actuator. Ensure this connection is secure and intact. If the cable appears broken or disconnected, it may need to be reattached or replaced.
Seeking Professional Help
If you are unable to identify or resolve the issue, it is advisable to consult a qualified technician or mechanic. They will have the expertise and tools to diagnose and fix any problems with your gas tank cover opening lever.
Remember to refer to your car's manual for specific instructions related to your Mazda CX-9 model, as lever mechanisms may vary slightly between different car makes and models.

Check the cable attached to the lever
To check the cable attached to the lever, you must first locate the lever. The fuel tank opener is typically located near the driver's seat, either as a lever on the floor at the right-side corner or as a button. Once you have located the lever, you can proceed to inspect the cable.
Start by visually inspecting the cable for any signs of damage or wear and tear. Look for any fraying, kinks, or broken strands in the cable. If the cable is damaged, it will need to be replaced. If the cable appears intact, you can then check its connection to the lever. Ensure that the cable is securely attached to the lever and that there is no slack or looseness in the connection.
Next, you can test the functionality of the cable by operating the lever. As you pull the lever, observe the cable's movement. It should move smoothly and freely without any binding or catching. Listen for any unusual noises, such as grinding or squeaking, which could indicate a problem with the cable or its routing.
If the cable does not move when the lever is operated, it may be broken or disconnected. In this case, further investigation is required. Carefully inspect the cable routing and ensure that it is not caught or tangled anywhere along its path. If the cable appears to be disconnected, you may need to remove interior panels or the inner rear wheel liner to access the back of the fuel door and inspect the connection more closely.
It is important to refer to your vehicle's manual for specific instructions and diagrams related to the fuel tank lever and cable mechanism. This will help you understand the exact routing of the cable and any necessary steps for removal or repair.

Check the release actuator at the fuel door
If your Mazda CX-9 fuel tank won't open, the release lever, the cable, or the release actuator at the fuel door may be broken. To check the release actuator, start by inspecting the lever and cable. If the lever is significantly loose, the cable may be broken. If the lever does not move or moves with too much effort, the cable or release pin could be dirty or corroded.
If the lever and cable seem intact, the issue may lie with the release actuator itself. The actuator is usually located near the fuel door or inside the fuel filler compartment. It can be operated manually or electrically, depending on the vehicle's design. Some vehicles have an electric actuator tied to the central locking system, which may require a diagnostic scan and computer reset if malfunctioning.
Before attempting any repairs, it is important to consult a qualified technician, especially when working around the fuel system. If you choose to proceed with repairs yourself, always exercise caution.
If you determine that the release actuator needs to be replaced, you can purchase a new one at an auto parts store or online. Ensure that the replacement actuator is compatible with your vehicle and includes safety features such as locking mechanisms and overload protection. The average cost for a fuel door release actuator replacement is between $224 and $277, but prices can vary depending on the vehicle.

Try opening the tank manually
If the fuel tank of your Mazda CX-9 won't open, there are a few methods you can try to open it manually. Firstly, check if the door is frozen or if the spring or release mechanism has failed. If the door is frozen, you can try pouring warm water on it to melt the ice. If the spring or release mechanism has failed, you can try using a plastic spackle knife to pry the door open. Centre the knife where the door opens and push in hard while prying it out; it should pop open.
Alternatively, you can try to manually operate the release mechanism. Open the boot and look on the left-hand side, just behind the tail light. You should see a small trim panel of about 6"x4". Carefully pry out this panel, and use a small torch or flashlight to see through the opening to where the release cable attaches to the fuel flap release mechanism. If you're lucky, you may be able to reach in and manually operate the release mechanism.
Another method is to use a screwdriver wrapped in a cloth to pop the door open. This will help prevent damage to the paint. You can also try using a credit card to release the door.
If none of these methods work, there may be an issue with the cable coming off the mechanism on the door. In this case, you may need to refer to the car's manual or seek assistance from a mechanic or a Mazda forum.

Safety precautions when opening the fuel tank
Safety should always be the top priority when opening a fuel tank. Here are some detailed safety precautions to follow when opening the fuel tank of your Mazda CX-9 or any other vehicle:
Prepare the Vehicle:
Park your vehicle in a well-ventilated area, preferably outdoors, and on level ground. Ensure the vehicle is securely parked and will not move during the refuelling process. Turn off the engine and make sure all passengers have disembarked.
Wear Appropriate Safety Gear:
Put on the necessary Personal Protective Equipment (PPE) for handling fuel. This includes eye protection, hearing protection, hand and foot protection, and flame-resistant clothing (FRC).
Inspect the Fuel Tank and Ventilation:
Before opening the fuel tank, check the fuel lines, connections, vents, and the tank itself for any damage or loose connections. Ensure that the air vents and valves to the gas tank are open. Inspect the fuel tank for any signs of corrosion or leaks.
Prevent Static Electricity:
If using a nozzle, ensure that it is in tight contact with the edge of the tank opening to ground any static electricity. If you are filling up portable containers, do so on the ground and not inside the vehicle, as this can cause static electricity buildup.
Refuelling Process:
During refuelling, fill the tank slowly and keep your hands steady to prevent splashes and spills. Keep an absorbent pad nearby to immediately wipe up any fuel spills or drips. Ensure that the gas cap is tightly screwed back on after fuelling to prevent leaks and debris from entering the tank.
Post-Refuelling Ventilation:
After refuelling, reopen all closed compartments, windows, and hatches to ensure proper air circulation and eliminate gasoline fumes before restarting the engine. Use a blower to dissipate fumes if necessary, and sniff for any lingering gasoline odours. Do not restart the engine until all fumes have completely dissipated.
Fire Safety:
Keep a fire extinguisher nearby as an extra precaution in case of any accidents or emergencies. Ensure that all flames, such as grills or cigarettes, are extinguished before and during the refuelling process.
By following these safety precautions, you can help ensure a smooth and safe refuelling experience for your vehicle.
