Could be bad fuel. I had the same problem drained the fuel, replaced and ran fine. Depending on the area of the country you are in, the fuel starts to turn after about I
believe 13 days:
Stability:
Ethanol blends can turn "SOUR" in as little as 2 weeks. Evaporation and oxidation are the two biggest problems effecting Ethanol blends. Ethanol is lighter than gasoline. When it sits in a tank that is less than full for a period of time the Ethanol rises to the top and evaporates into the air. This is especially true in a vented fuel system. When a tank is less than full the Oxygen in the air in the tank reacts with the fuel and causes the build up of gums and varnishes. Evaporation leads to a poorer quality fuel and the gums and varnishes can plug filters, injectors and carburetors. EhtanolRx and Sentry will help.
Water:
Ethanol is a hygroscopic liquid, meaning that is readily attaches to water. It it also fully miscible (mixable) with water. In very small amounts this is not a problem. But when the saturation exceeds a specific amount is becomes a major problem called Phase Separation. The amount of water Ethanol can safely absorb is dependent on the temperature of the fuel. At 70°F it is .5% (.005) of the volume. If it exceeds this amount the Ethanol and water will fall from suspension and sink to the bottom of the tank forming an Ethanol /Water layer that can produce acids and cause major engine failures. At cooler temperatures it is less and at higher temperatures it is more. This is especially a problem during transportation and storage of fuel. A hot tank may have 1% water, when is cools off it can exceed the amount and cause phase separation. In the case of storage tanks this may go undetected and delivered directly to your tank. This can also be a problem when Ethanol is added to a tank that has water in it already.
I would start with changing fuel, then check fuel pump.
probably a broken wire running from the solennoid to the starter push button
Probably a stuck solenoid.
ignition coil
Check engine light on?? Not running on all cylinders?
It can and it will eventually cause the engine to self destruct and you will be not running at all.
Could be no air running through it such as sitting in traffic or slow moving
Discharged battery possibly or trouble with starter.
Sounds like a failed starter.
I suggest that the cause may be related to the starter. Because, if the starter is staying engaged with the ring gear on the flwheel after you start the engine it will cause the starter to overheat, thus preventing the starters operation until it cools.
The starter on a 750 Kawasaki jet ski is typically lubricated using a light machine oil or a specific lubricant recommended by the manufacturer. It's essential to check the owner's manual for the exact specifications and recommended products. Regular maintenance, including lubrication, helps ensure smooth operation and longevity of the starter motor. Always avoid over-lubricating, as excess oil can attract debris and cause wear.
A 4.3L V6 engine may exhibit symptoms of running on only four cylinders due to issues such as a faulty spark plug, ignition coil, or fuel injector that can cause misfiring or poor combustion. Additionally, vacuum leaks, low compression in one or more cylinders, or problems with the engine's fuel delivery system can also contribute to this issue. Diagnosing the exact cause typically involves checking the ignition and fuel systems, as well as performing a compression test on the cylinders.
once it starts, the starter should disengage... after you release t he key. if it makes an awful noise while running, then maybe the starter is dragging... but if not then the starter will not cause it to stall
