Help Get my Boat Running! 05 210 with PCM330

I'm on the electrical side trouble shooting now. I confirmid with the key on the injectors have two 12v signals. When you crank it voltage doesn't change. If I crank it and manually ground the injector the injector will fire. What gives Ecu the ok for the the injectors the signal to fire? Crank sensor and map sensor may be my next move

Just based on general engine troubleshooting, the fact that you can't see RPM is a big red flag, and your injectors aren't firing sounds like crank position or cam position sensor depending on which one the engine uses to determine when to fire. Start there.

I'll just leave this here as well.... I am having a no start issue that is similar to this.... I have an 04 SANTE, about 550 hours, owned it for 3 years, new plugs then, all other maint up to date, never had any drive-ability, rough running, hesitation, etc before now.

On the lake yesterday going through a slow zone, had been out for maybe an hour, engine stalled with no hiccup or any warning. Tried restarting, cranks fine, still no start. Checked the obvious, fuel level per gauge, just filled up 2 days prior, should be plenty, lanyard, loose connections, breakers, fuses, all ok. Went as far as pulling out safety switch and jumped it together. Could clearly smell fuel, both pumps turning on. Pulled plug wires for visual, pulled out one plug, looked fine, some fule soak tho. cranked at WOT to clear flood, cranked and checked for spark, all ok. No fuel psi gauge at the moment, but some sprayed up when pushing the test port valve, will check actual psi tomorrow. Pulled off dizzy cap and it was very fuzzy and rotor end was pretty black so I used a wire brush to clean them up while stranded, still nothing. Replaced cap and rotor today, no change.... was really hoping that was it.

Dinked around with checking voltages at pumps, ok tried checking injector pulse, a bit too fast for my meter but definitely pulsing. Crankng voltage ok. Unplugged pretty much every connector to check for the green, all look ok. Now when i crank it I get a MAP sensor fault message in the dash display. Removed that for visual, looks fine i guess.
What am I missing???!!

Ground wires on engine. Bottom of flywheel housing Left side sitting in seat.

i will check this along with the others, thanks for the suggestion

Fixed. Ignition coil was my culprit, not quite good enough. Had enough juice to jump plug gap out of engine but not enough to spark under compression.

Glad to hear

This ended up being the Fuel injection Computer, boat is running. I forgot to post a resolution but wanted to thank everyone for the troubleshooting help. I did every troubleshooting tip in the thread, Put the new computer in and it fired right up.

Now you have a new fuel system, so there is that piece of mind.

Glad you got it squared away.

make sure tour anti siphon valve on tank is clean. as for low pressure pumps mine would run for ten minutes heat up and stop working until cooled off for hours(intermittent pressure issues). drove me nuts. It is my first go to and the most common issue to your symptoms. replaced at least three over the years.

just curiously, can anyone clarify what he is referring to ??
