NEED HELP WITH BOAT NOT STARTING

[cmcoyner1980]

PLEASE HELP WE ARE TRYING TO GET THE BOAT GOING FOR MY DAUGHTERS BDAY

--------------------------------------------------------------------------------

OK I WENT OUT TODAY TO TEST OUT A NEW ALTINATOR EVERYTHING WAS FINE I SWITCH MY PPASS TO RPM BASED AND ABOUT 4 MIN DOWN LAKE THE MOTOR STARTED POPING AND BACKFIREING THROUGH THE INTAKE.
I CHECKED TO SEE IF I HAD FUEL AT THE TEST VALUE ON THE FUEL RAIL HAD GAS SHOOT OUT BUT WITH AIR ALL SO. IM THINKING MABY CRANK SENSOR ? THIS IS A 2005 22V WITH A NEW MARINE POWER 340 HR GM MOTOR. I HAVE NOT CHECKED THINGS LIKE CAP AND ROTOR YET BECOUSE THE BOAT WAS RUNNING FINE TILL I SWITCHED THE PERFRECT PASS FROM SPEED THE RPM BASED. WHEN YOU CRANK THE MOTOR IT ACTS LIKE IT WANTS TO RUN BUT JUST WONT ALSO WONDERING ABOUT KNOCK SENSOR

Backfiring is timing based so you're on the right path to what may be wrong but you will need to get a diagnostics computer on it for fastest diagnosis. Just to see if you can start it, rotate the distributor clockwise (retarded) or counterclockwise (advanced) about 10* while someone cranks and see if it gets better or starts. Keep in mind you'll have to retime it after you solve the problem. Good luck and stop yelling at me.

Hope you read your other post..where I suggested to check that first. As not to waist alot of time or money without checking the simple stuff first. As for the gauge. the senders go bad all the time. You need to pull the floor up to access the sender. Undo the wires from the sender.Turn the key on the gauge should read empty.check for power on the pink wire..check black for good ground. If both check good touch them together and the gauge should goto full.

I am soooo confused....you have 2 different screen names with 2 different boats. So in the future if you need help make sure you tell us which one of your boats we are talking about.
