What to do if my Cannondale Offroad Vehicle engine turns over but won't start?

If your Cannondale Offroad Vehicle's engine turns over but doesn't start, several factors could be the cause. It might be due to fuel deterioration, water in the fuel, or an empty tank, in which case you should drain the old fuel and replace it with fresh fuel. A fouled spark plug can also be the culprit, so replace it with a new one. Other potential issues include low battery voltage (charge or clean the battery), a faulty fuel pump, clogged fuel filter, a clogged or kinked fuel tank vent hose (verify fuel pump operation, check electrical connections, check for fuel system leaks, and replace the fuel filter), debris on the crankshaft sensor (check the sensor), or, for MC500 models, ECU power-down (reset the ECU by turning the ignition switch off and then on).
