My Yamaha G22 Golf Cart has no spark and won’t start

Please help me with my Yamaha G22 golf cart. It just won’t start, and there’s no spark at all. I’ve tried a few things, but nothing’s working. It’s really messing with my weekend plans on the course.

Response

I totally get how frustrating that is! I had a similar nightmare with my G22. In my case, changing the spark plug was what fixed it.

Detailed Solutions that Worked

1. Replace Spark Plug

  • What I Did: Checked and replaced the spark plug.
  • Outcome: The golf cart started successfully.
  • Personal Experience: I initially overlooked the spark plug, thinking it was fine since it was new. Turned out, the electrode was missing. Replacing it fixed the issue.
  • Estimated Cost: $5 – $15
  • Time Needed: 15 – 30 minutes
  • Detailed Steps:
    1. Locate the Spark Plug: Find the spark plug on your golf cart’s engine. It’s usually on the top or side of the engine.
    2. Remove the Old Spark Plug: Use a spark plug socket to carefully unscrew and remove the existing spark plug.
    3. Inspect the Spark Plug: Check for signs of wear, damage, or fouling. Look for a broken electrode, which is a common issue.
    4. Set the Gap on the New Spark Plug: Using a spark plug gap tool, set the gap on the new spark plug according to the manufacturer’s specifications.
    5. Install the New Spark Plug: Carefully screw in the new spark plug by hand to avoid cross-threading, then tighten with the socket.
    6. Test the Golf Cart: Start the golf cart to ensure it’s running smoothly.
  • Expert Tip: Always use a torque wrench to tighten the spark plug to the manufacturer’s recommended torque setting to avoid over-tightening.

2. Check Valve Movement and Lash Adjustment

  • What I Did: Inspected the valve movement and adjusted the valve lash.
  • Outcome: Improved engine performance and starting.
  • Personal Experience: After adjusting the valve lash as per the manufacturer’s specifications, the engine started and ran smoothly.
  • Estimated Cost: $0 – $50 (if DIY)
  • Time Needed: 30 – 60 minutes
  • Detailed Steps:
    1. Access the Valves: Open the engine compartment and remove the rocker cover to expose the valves.
    2. Inspect Valve Movement: Manually turn the engine and observe the valves. Ensure they are moving freely and fully.
    3. Measure Valve Lash: Use a feeler gauge to measure the gap between the rocker arm and valve stem.
    4. Adjust as Needed: Adjust the lash to the manufacturer’s specifications by loosening the lock nut and turning the adjustment screw.
    5. Recheck and Reassemble: Double-check the lash settings, then reassemble the rocker cover.
  • Expert Tip: Perform this adjustment when the engine is cold for the most accurate settings.

3. Verify Fuel Quality

  • What I Did: Checked the fuel in the tank for quality and type.
  • Outcome: Ensured the engine received the correct fuel for optimal performance.
  • Personal Experience: Realized the importance of using the right fuel type for my golf cart’s engine.
  • Estimated Cost: $0 (if DIY)
  • Time Needed: 10 – 20 minutes
  • Detailed Steps:
    1. Inspect the Fuel: Open the fuel tank and visually inspect the fuel. Look for any signs of water or contamination.
    2. Smell the Fuel: Sometimes, bad fuel can be identified by its smell. Stale or sour-smelling fuel is a bad sign.
    3. Drain and Replace if Necessary: If the fuel is suspect, drain the tank and refill it with fresh, high-quality fuel.
  • Expert Tip: Always store your golf cart with a full tank of fuel to minimize condensation and fuel degradation.

  • Valve Lash Adjustment Frequency: Regular valve lash adjustments are often overlooked but can prevent many engine issues.
  • Fuel Storage Tips: How you store your golf cart can impact fuel quality. Always use a fuel stabilizer if the cart will be stored for extended periods.
