Help trouble shooting no start needed. 2006 SAN.

[MNSuperAir]

Been having an intermittent starting issue on our new to us 2006 SAN 210. 3 times this year it has happened. First 2 times it happened we were using the boat and after shutting the boat off to swim a little it wouldn't start. Turns over great, just won't fire. No missfire or partial fire either. Like a loose ground or something. We were able to get it to start by cycling the batteries and key/pad a few times. This weekend no luck, wouldn't fire after doing that. Looking for suggestions of what to check or if anyone knows what pins in the harness to check for continuity or 12V.

Thinking this boat may have been a salt water boat.Having similar issues on the ballast pumps but can get those to work by wiggling the harness in the port locker. Engine is the 330 PCM of course.

Thanks for the help.

Not knowing which motor can only guess, sure sounds like the LP fuel pump or the cap. Your mention of salt use, if you have corrosion throughout before doing anything else I would go through and clean up all your connections where required and if unsure when the last tune up was change the cap and rotor and inspect the plugs.

How much corrosion you you expect for a salt water boat? Not sure if it was. Engine is the 330

look at the motor, tranny, v drive mounts and the locking nut on the shaft poking out of the v drive. if it was in salt water, all will be very corroded and rusty. it is 10 years old, so some rust is normal, but salt water or very brackish water will exacerbate the problem greatly
