Gas Golf Cart Won't Start? Here's the Fix Order

Short answer: Most gas golf carts that won't start have a weak battery, old gas, a fouled spark plug, or a safety switch that isn't making contact. Work through checks in order, from simplest to most involved, and you'll usually find the problem before you touch the carburetor. Start with the battery and cables, then fuel, then spark, then the switches, and save the carburetor for last.

Check the Battery First

A gas golf cart still uses a small battery to run the starter-generator, lights, and ignition. If that battery is weak, the cart may click, crank slowly, or do nothing at all.

• Look at the battery terminals for corrosion or a loose cable.
• Turn the key or push the pedal and listen for a click or slow crank.
• If the cart cranks strong but won't fire, move on to fuel and spark.
• If it barely cranks or does nothing, the battery or cables are the likely cause.

Battery acid and battery testing can be harmful if handled wrong. If you see corrosion, swelling, or a smell, have the battery checked rather than working on it yourself.

Check the Fuel System

Gas sitting in a carburetor for weeks or months turns stale and leaves a varnish behind. This is the single most common reason a gas cart won't start after it sits in a shed or garage all winter.

1. Check the tank for fuel and smell it. Old gas smells sour or like paint thinner.
2. Check the fuel line for cracks, kinks, or a stuck shutoff valve.
3. Check the fuel filter for dirt or a clog.
4. If the cart hasn't run in a long while, drain old fuel before adding fresh.

Check for Spark

No spark means no fire in the cylinder, no matter how fresh the gas is.

• Pull the spark plug and look at it. Wet, black, or fouled means fuel is reaching the cylinder but not igniting.
• A dry plug after cranking points back to a fuel delivery problem.
• A cracked plug, worn electrode, or oil-fouled plug should be replaced.
• If the plug looks fine, the ignition coil or wiring may need a closer look.

Check the Starter-Generator

The starter-generator does two jobs: it cranks the engine to start it, and it charges the battery once running. A worn starter-generator can crank weakly or not engage at all, even with a good battery.

• Listen for a single click with no crank, which can point to the starter-generator or its solenoid.
• Check that the connections at the starter-generator are tight and free of corrosion.
• If the battery tests good and the cart still won't crank, the starter-generator or solenoid is worth inspecting.

Check the Pedal and Key Switches

Gas golf carts have safety switches built into the accelerator pedal and sometimes the brake or key switch. If one of these isn't making contact, the cart won't crank even with a good battery and fresh fuel.

• Press the pedal fully and listen for a click from under the dash or at the pedal assembly.
• Wiggle the key while turning it, since a worn key switch can lose contact.
• Check the micro switch under the pedal for dirt, corrosion, or a broken spring.
• A stuck or misaligned switch is a common, inexpensive fix once it's found.

Check the Carburetor Last

If the battery, fuel, spark, starter-generator, and switches all check out, the carburetor itself may be gummed up inside from old fuel. This usually shows up after a cart sits for a long stretch without running.

• A clogged idle jet or float bowl can keep the engine from getting fuel even with a full tank.
• Carburetor cleaning involves small parts and precise adjustments, so this is the point where most people call for help.
• Running the cart dry before storage next time helps prevent this from happening again.
