E-Z-GO golf carts are one of the most popular models of golf cart on the market. They have been in existence as a company for several decades and produce golf carts of varying types and models. The two types of propulsion offered for E-Z-GO golf carts are gasoline and electric-powered carts. If you own a gas-powered E-Z-GO golf cart, you will run across the problem at some point of the cart failing to start but still having a spark.
Verify that your golf cart lights (if installed) were not left on. If they were, then your battery charge may just be low, requiring recharge or replacement.
Check to make sure the golf cart transmission selector is in the "park" position. Some models of E-Z-GO gas-powered carts may fail to start with a charge if the selector is not fully in the "park" position.
Don your acid-resistant work gloves. Then, twist the battery connections back and forth by the battery terminals and attempt to start the golf cart. If the cart starts or comes closer to starting than before, you will need to take time to wipe down your batteries and reattach the connections. If your cable connections are significantly corroded and the connections to the battery were firm, then replacement of the cables will be required in the short term to prevent future problems with starting your E-Z-GO golf cart.
Visually inspect the ignition wire for corrosion and connection. The ignition wire goes from the key of your golf cart to the starter solenoid. The wire will plug in to the solenoid and it is not uncommon for it to become dislodged during heavy use of the cart. If it has, reseat the wire into the solenoid. If the wire appears corroded, you should don your work gloves and wipe down the wire and attempt restarting the golf cart. If the cart will not start, then you will need to replace the ignition wire.
