Fuel starved
 
Put my boat (3.0L) in the garage for the winter last Oct. No fuel
stabilizer. 1/2 tank of gas.

Pulled it out periodically to start it...no problem.

Hadn't pulled it out since December so I pull it out a couple of weeks
ago and couldn't get it started. Fuel line to the fuel pump was dry.
No time to troubleshoot further so I stuck it back in the garage. Put
fuel stabilizer in at that point.

Pulled it put today. Sprayed carb-cleaner down the carb to give it a
kick.

It started up fine and ran very smooth.

Ran smooth for 5-10 minutes and then stopped dead. Won't start. It
will sputter if I spray carb cleaner in it, but it's not getting fuel.

What probably happened?

Thanks.

Best clue: Fuel line to pump is dry.

Check to see if the outlet valve at the fuel tank has been shut off.
Or, if you have an inline filter between the tank and the fuel pump
check to see if you have fuel to that point. Work back upstream until
you find fuel, and then see why it's not getting to your pump. (Maybe
your neighbor's teenager has been fueling his jalopy all winter via a
siphon hose and your fuel tank? Wouldn't be the first time.....)

Depending on the design of the fuel pump, you may have had enough fuel
collected there to run a small engine for a few minutes, and then it
would "stop dead" and not restart.

The fuel pump, if mechanical, may have just started to fail last start,
now when trying, the diaphragm failed completely and no pumping. As
Chuck said, trace back to where you find fuel. If present up to the
pump(or water separator/filter) ck for good seal there, as an air leak
will let the fuel pump suck air instead of fuel. If the system is
tight,the pump is probably bad.

Could be varnish in the carb jets. Without rebuilding the carb, you
can get liquid carb cleaner and run it straight into the carb. Break
the fuel line somewhere and hook the can up to it upside down like an
IV.

Thanks guys.

I suspect the fuel pump too. Just surprised me that it would run fine
for as long as it did. I didn't think that much fuel could be in the
system to run the 3.0L 5-10 minutes with a non-functional fuel pump.

I agree that a dry line between the tank and the fuel pump is the key.
I didn't check that again after I got it running and then when it shut
off.

I don't think it would be the carb jets because it did run for awhile.
Make sense? However, I did wet it down with carb cleaner.

I would pull the tank draw connection and see if there is something plugging
the filter, or even if you have gas in the tank.
