Got towed in last week (first time being the towee and not tower) 2008 glastron 225 GT with 5.0 GXI-J with SX-A 1.60 outdrive. Engine only has 125 hours. This is a new boat to me this season and my first EFI boat.
so my boat ran fine all day on the lake and we stopped on the way back to the dock. when I stated up and put it in gear it would not move. So I turned it off and it restarted fine and I put it in neutral and tried reving the engine and it died. So it starts fine but seems to not to be getting enough fuel.
So Here is what I did to diagnose and hopefully solve:
I replaced the fuel filter( gas looked good, no water or debris) checked and cleaned anti-siphon valve, pickup line and tank vent. Then I replaced the fuel regulator. Screen was partially clogged with paint chips.
Started it up and the pump was whining and I had the same result where it would start and then stall after 20 seconds?FYI the pump did not whine last week when I got towed in. So I was stumped and thought for sure it was the pump.
I checked the electrical connection on the low pressure pump and it had no corrosion and had a good connection. The High pressure pump connector did not ?click in? like the low pressure pump and seemed to be loose. I made sure it was on as tight as I could and started it up with the pressure gage connected on the low pressure pump.
Ran great and pump whine went away. ?low pressure was at 14 psi..then I restarted with the gage on the rail (high pressure) and it read a constant 73 psi?.Took it out for a ? hour test drive and ran great. Went back to dock and waited 20 minutes ?then started it up and again ran great for another ? hour.
The only 2 changes that I can think of were:
1) If my high pressure pump was not connected or loose?.would that be the reason why it would start but not run or rev past 20 seconds?
2) Or is it possible that just by hooking up the pressure gage on the low side was enough to stir the blockage in the pump if that was indeed the problem
Finally I know both readings were a little high. Do you think those readings are ok?
Thanks
