Need to check both....Lift pump will only run for 7 - 10 seconds and float switch will shut it down when FSM is full....High pressure pump runs all the time. If it runs with primer ball then its most likely either float switch bad or lift bad. You can listen and hear the lift pump come on when ignition is turned on however if float is stuck closed it wont come on thinking the FSM is full.

Len,

I would assume your speaking of the lift pump and not the High pressure pump?

Fuel pressure pump is not working or float switch is stuck....Almost anything else would give you an alarm and wouldn't run for a minute with primer ball.

OK, So all the maintenance has been done and up to date (now has 460 hours on the engine) and after this issue 1st started I replaced both the water separator filter and the inline filter. I'd inspected the fuel supply hoses all the way down and into the fuel tank. No kinks or blockages of any kind. There was no fuels in the overflow canister or in the vent line.
Anyone have other ideas or suggestions?  Huh?

Found nothing in the float switch or in the the FSM. Had taken all the fuel out and poured into clean jar and inspected for just that.

possibly sucked up sentiment and stuck in float switch when you ran it out of fuel.....Never good to run a tank down that low.

I did make several attempts and I did check the valve and canister and have not found any fuel in it

  If when you originally ran out of fuel, did you make multiple attempts to start motor unsuccessfully ?? If so ,you may have forced fuel into the overflow canister....If you did it needs to be emptied. (has bicycle looking tire valve).. If canister has gas in it you wont start....Its a fail safe.

I have a 2009 135HP engine in a 2010 18' Crestliner and it ran out of fuel (gauge said I had 41% remaining which is now another issue I have to deal with) and had just got up on a plane and 30 seconds or so later the engine quit. After refilling a 26 gallon tank with 26.7 gallons, I went back out and it would not restart (yes I turned the key on and off as prescribed) I've replaced the fuel filter and water separator filter and that did not help. Installed a primer bulb and I could get it to run for about a minute once up on a plane and then the engine stalls. Re- prime the system via bulb and she'll restart. Idle in gear at around 1200 rpm's and she'll run for about 10-15 minutes and then stall. I've had a friend of mine run the boat and while I kept squeezing the primer bulb occasionally and the engine will keep running just fine. With the FSM full of fuel I'd checked the voltage - Lift Pump: 3.04 v on cold start, it did not show voltage once running up to and during stall. I then drained the FSM fully and checked voltage again. While turning the key on, then off and on again the lift pump had no voltage. The float switch continued to show voltage with the key on or off or with the engine running. The high pressure pump has no voltage with key off (expected) and when key is turned on had 12.04 volts for 5-6 seconds and then drops to zero. I've inspected all fuel lines and connections and all are in in really good shape including the hose attached to the float switch. I did see while trying to restart the engine the very 1st time after running out of fuel "Lift pump float switch not working properly."
Now, I've read all the threads about the lift pump and FSM Float switch. Is it likely the lift pump is at fault here? It seems based on what I've read that one or both of these parts could be the culprit. However, to my way of thinking back in my 35 years in the auto service industry, just running out of fuel shouldn't cause this problem. It does not make sense. Oh, this engine has never been in or near saltwater. Am I missing something? Will the lift pump burn out without fuel? Any ideas? Any help is greatly appreciated.
Thanks in advance,
Gary
