One of the most frustrating situations a car owner can experience is showing up at a service station with a car with the fuel cap or fuel door stuck. It always seems that “Murphy” and his “Law” tend to show up at the most inconvenient times. Such is the case when it comes to discovering that your vehicle’s fuel door does not open as designed.
Whether it’s due to an internal spring, lack of lubrication, a bent fuel door, or issues with the button trigger lever inside the vehicle, there are a few ways to fix the problem that’s causing this problem, so you can contact a professional mechanic. local. and have the damaged gas cap repaired.
Here are some of the most common troubleshooting methods to find out why your vehicle’s fuel door won’t open.
Method 1 of 2: Inspect the fuel door lever or button
In many modern cars, trucks, and SUVs, the fuel door is closed from the outside to prevent unauthorized persons from opening the fuel door and tampering with or stealing the gasoline or diesel fuel that powers your vehicle. The fuel door is opened by a mechanical lever or a push button switch.
Lever actuated fuel door devices are typically connected to a spring loaded locking mechanism located behind the fuel door. As the level is pulled up, a cable attached to the lever and the spring-loaded locking device is pulled at the same time. When this occurs, the spring-loaded lock will “click” on the fuel door to open it, allowing you to put fuel into the fuel tank.
In a button controlled fuel door trigger, an electronic signal is sent through electrical wires to a solenoid that activates the locking mechanism to open the fuel cell. This type of control system sends an electrical signal through a relay, to the fuse box, to the wire that is connected to the solenoid, and then to the solenoid itself.
Because there are various fuel door locking devices and systems that are activated inside the vehicle; There are different steps you will need to take to fix the cause of the problem. Here are the steps to follow to track problems with a cable operated mechanical fuel door and an electrically operated fuel door:
Step 1: inspect the lever for damage: In many cases, a mechanically operated fuel door will not be able to open if there is mechanical damage to the handle. In many cases, the handle is connected to a wire under the floorboard on the driver’s side. This connection can be broken if the handle is pulled hard enough.
To inspect this component for damage, follow these guidelines:
Remove the dash or floor cover where the fuel door lever is located.
Inspect the connection of the lever to the cable. If the connection is broken, you will need to buy a new lever from the auto parts store or dealer and replace the lever.
Step 2: Trace the wire rope from the lever to the fuel door: If during your initial physical inspection you determine that the lever and cable connection are good, you will need to trace the cable to the fuel door.
It is a good idea to have a second person help you with this test, as one person will have to pull the lever at the source, while the other person inspects the connection on the fuel door for cable activity.
Locate the attached wire connection behind the fuel door. In many cases, you will have to remove the cover behind the trunk to access the fuel door cable.
As one person pulls on the cable, watch the action of the cable. If the cable moves but the door does not click, the problem will be the locking mechanism and not the cable. If the cable does not move, but is secured in the lever, you will need to remove and replace the cable, as it is most likely damaged somewhere between the two connections.
Steps to troubleshoot an electrically operated fuel door:
Most modern automobiles have an electrically operated fuel door lock mechanism. This type of system uses a button typically found on the dash, center console, or floor that, when activated, sends an electrical signal to the locking mechanism behind the fuel door.
There are many…
