How do you Troubleshoot a Gas Club Car Golf Cart?

Regardless of what the gauge indicates, it is important to verify the fuel level. How do you Troubleshoot a Gas Club Car Golf Cart? I have personally witnessed a situation where a mechanic spent three hours trying to identify the cause of a “full” tank that was not able to deliver fuel, only to discover that a stuck fuel tank float was to blame.

Please ensure that the battery is completely charged and that there is no corrosion on the terminals. If you have confirmed that the key switch and the cables connecting it to the solenoid are functioning correctly, and you still do not hear a click, then let’s inspect the solenoid.


After confirming that the electrical system is functioning properly and the engine is still not starting, try adding a few drops of gasoline or using engine starter fluid before reinserting the spark plug.

Once the spark plug has been replaced, attempt to start the engine and observe whether it shows any signs of starting. If it sputters and makes an attempt to start, then it is likely that the fuel pump is causing the issue, followed by the carburetor.

The majority of gasoline-powered carts are equipped with a fuel pump that is connected to three hoses. One hose serves as the inlet for gasoline, another hose acts as the outlet, and the third hose connects to the crankcase vacuum.

The crankcase pressure, generated by the piston’s up-and-down motion, causes the diaphragm inside the fuel pump to move back and forth. The diaphragm pulls in gasoline and then pushes it out through the other hose when the pressure changes.


Inspect the air filter element for any dirt or blockage, as it may impede the engine’s air intake and lead to stalling. To determine if this is the issue, attempt to start the engine without the air cleaner in place. However, do not leave the air filter removed permanently even if the problem improves.

The primary purpose of the filter is to safeguard the engine from dirt, as repairing the engine incurs significantly higher costs compared to replacing the filter. In the interim, it is advisable to remove any excess dirt and dust by either blowing it out using air pressure or manually cleaning it.

Spark Plugs

To begin, we will focus on the spark plug. Take out the spark plug and assess its condition. Is it covered in oil or fouled? Is there any bridging in the gap? If everything appears to be in order, proceed by grounding the spark plug threads against the engine’s bare metal surface. Rotate the engine a few times and observe for a spark in the electrode.

If the spark plug is correctly connected to the spark plug cable and you have established a proper connection to the external ground, the absence of a spark could indicate a potentially faulty coil.

Frayed Wires

The presence of frays can lead to engine malfunctions; therefore it is important to resolve this problem by either replacing the wires with new ones or using electrical tape as a temporary solution.

It is recommended to replace frayed wires instead of depending on electrical tape as a permanent solution.

  1. Ensure that there is sufficient fuel in the gas tank for operation. If necessary, examine the tank using a flashlight. Refrain from utilizing old gasoline that has been stored and instead, add fresh gasoline when required.
  2. To inspect the oil level, detach the oil dipstick and ensure that it is either at or slightly above the add or fill indicator. If required, add oil as per the instructions provided by the manufacturer, and make sure to use the suggested weight of oil.
  3. Inspect the golf cart battery and ensure secure cable connections. Tighten cables with an adjustable wrench. Check and fill the water level with distilled water if low. Remove any corrosion from terminals using a brush.
  4. Examine the wiring and switches. Inspect the electrical wiring for any instances of cuts or abrasions, and proceed to mend them using electrical tape. Examine all switches to ensure that the wiring connections are in good condition. If any loose connections are found, use pliers to crimp them, wrap them with electrical tape, or tighten them with a screwdriver.
  5. To gain access to the carburetor, the air filter must be taken off from the engine. Utilize a screwdriver to eliminate the retaining screw. Apply cleaner into both the carburetor and the throttle linkage, which can be found just below it. Finally, reattach the air filter back onto the engine.

Tips and Tricks

  • To ensure normal operation, it is important to thoroughly wash the cart to eliminate dirt, debris, and grime. Accumulated debris can frequently cause interference.
  • It is advisable not to spray excessive amounts of water onto the engine.
  • Exercise caution when dealing with electrical wires, connections, and batteries. It is essential to wear protective clothing, gloves, and eye protection.
  • Ensure that there is a safe distance between an open flame and both gas and gas tanks.
