Hey, thanks for writing in. You need to try to turn over the engine by hand at the front pulley using a socket and breaker bar to see if engine will turn with the spark plugs out.

If the engine cannot be turned then you have bent the rods in the engine. This is because the water could not be compressed and the piston rods are the first thing to bend. You will need to replace the motor if this is the case.

If you can turn the motor over with the breaker bar in a clockwise rotation more than one complete turn then try and use the starter to turn over the motor. If starter will not turn motor then it may be burned out and need to be replaced to get engine to turn. If you can get it to turn with starter now then install plugs and see if it starts.

The problem is unlikely related to spark plugs or a capacitor. I would recommend having your battery tested, and replaced, if necessary. After your battery is replaced, your throttle should be relearned with a professional scan tool. There is also...
