Boat has run completely fine... Save one issue a few weeks ago where the MC cruise never seemed to want to get up to speed but when I bumped it up a few tenths it zoomed up and overshot like normal..


Anyway every running fine and we tied up for a while.. when I went to idle while we were untieing the motor just died. Now it cranks no problem but will not start. Based on everything here I am assuming the fuel pump. Always keep it as close to full as possible I am lucky if it ever even gets to 1/2 tank.

Now I just need to wade through all the threads to figure out what PN I can get from an autoparts store tomorrow :( and find the one that shows how to just replace the pump.

2007 LY6 with 265 hours.

don't be too quick to replace the pump. check your connections at the gas tank, disconnect then reconnect and check for fuel pressure first, then check the safty lanyard

It would be unusual for an 07 that never was run low to fry the fuel pump. Check the fuel pressure as snork said before laying out the cash for a new pump

wish i could say the same but mine went out on my 07 at 250 hrs. never ran lower than 1/2 tank due to the known issue. dealer told me it was about time!:rolleyes:

If you need a fuel pump, here is the link to "fuel pump 101"....

http://www.mastercraft.com/teamtalk/showthread.php?t=25783&highlight=fuel

I just went through that thread, as I'm heading to BillyChinook next week and with 320hrs on my 06 X2, I figured it would be good to have a spare on-hand... I went with the AirTek E2065, some APEusa.com fuel-line/clamps and the special fuel-line removal tool. Hopefully, having all that on-hand is good insurance against having an issue.

was going to go run and get a gauge but just for fun, I pushed in the schrader valve with the key in the on position and nada no fuel or pressure relef came out so I have to think it's pump.


as for lanyard, It cranks fine. I though the key and gear position issue it would not even let it crank?


Making a list and heading to autozone.

Is there a fuse in the harness somewhere for that pump? if so maybe check that

Not that I am aware of????? I will check all of that really quick guess I could pull harness and see if it is getting power first too.

It was running idle for about 2-3min and just quit and would not restart.

So I assume I should be getting power (12v?) to one of the 3 pins on the fuel pump harness?

All 3 are reading 0. Now I don't know where there would be any fuse or anything to check for the pump.

My 08 would crank with lanyard pulled. My 09 does not. FWIW

pulled layard just for hell of it with key on and everything shuts down.. so not that..

However, I just learned something that may be useful for others. That harness has a black, green, and gray wire. The power is the gray wire. When you turn the key to on position it only clicks the relay on for about 1 second. So you need a second person or a way to connect meter and look for that. I kept testing and seeing no power but it does go to 12V right when you click key so I am 99% sure its the pump now.

I have seen on two occasions (different boats) where the wire comes loose off the back side of the lanyard switch.

Ran perfect on the water. Thanks to the ton of hard work people contributed here. I got it done under $100 and a couple hours work. I was lucky enough to have the better corrugated fuel line and reusing was no problem.

Congrats and good work. You should be good now. My 2044 has been going for hundreds of hours now.;)
