My 2001 speedster 240 efi will not start , I brought it out on the lake for the first time this year yesterday and it started and stayed idling for a few minutes . Then it died out , started again , then died out immediatly and contiued like that for a few more tries. Now it will not start at all .

It will turn over , and i changed the plugs , and changed the fuel over thinking it may be bad gas . I am stumped and cant afford to bring it in to the dealer .

Can anybody please help me thru this .
 
Fuel...

Sounds like you have a fuel delivery problem. Your fuel flow path goes like this. Low pressure electric fuel pump draws fuel from the tank, to the engine driven pulse pump, through the fuel/water separator, to the vapor separator which is controlled by a float, then the high pressure pump sends it to the fuel rail.

The way you describe your problem it sounds like something in the low pressure side is not keeping the vapor separator full for the high pressure pump. Make Sure the low pressure pump is working and the pulse pump is OK. If they are, either the fuel/water separator is plugged, or the float in the vapor separator is stuck in the up position.

Check this out and let me know what you find.

how do i check the float ??

I just put in a new fuel/ water seperater, so i dont think its that , unless its the wrong part , but i still have the old one i could try .....

any tips on how how i check out the float or to see if the engine driven pulse pump is working ??

Thanks ,

P.s this engine is a nightmare .......

Naw they're not that bad. I work as an automotive tech and if you understand electronics and fuel injection they're all the same.



If you have a fuel pressure gauge the low pressure pump should put about about 4-6 psi, and the pulse pump 1-3 psi. If you don't have a pressure gauge just put the fuel hose from the pumps one at a time in a container and check for good flow. If that looks good check the hose from the fuel/water separator for flow. If all is good there you will need to undo the vapor separator from the block (three bolts) and remove the cover (six or seven bolts). Make sure the float moves freely and that the filter on the bottom of the high pressure pump is not plugged.

Any chance you have a fuel flow diagram?

DO you have any idea where I may find a diagram of the components in the fuel flow. What I thought was the fuel flow direction seems to differ from what you've told me.
Thanks
 
This is where we're at now....

we got it down to the fuel fills the fuel/water separater , but doesnt reach the vaporiser......

we took the vaporiser apart and the float was fine , then we put it back together and tried it , then took out the drain pug on the vaporiser to find nothing at all ....

does the vaporiser have a pump inside of it or does the pump that sends the fuel to the seporater supposed to pump it all the way thru

There is a pump in the vapor separator, but it sends the high pressure fuel to the fuel rail. It can't draw fuel on it's own, it needs to have the separator filled with fuel to work.

Are you getting fuel coming out of the fuel/water separator? If you are then the vapor separator should be full of fuel. When you took it apart and checked the float did you try to blow through the hose? Even though the float is moving, the opening it controls may be plugged. With the drain plug out try to blow in to the vapor separator. If you can't that's where your problem lies. Let me know what you find.

we checked the hose coming from the separater to the vaporiser and that didnt have fuel but had air and the seperator had fuel inside of it .
 
Sounds like the fuel/water spearator is wrong or plugged. Also take the fuel/water separator filter off and try to blow backwards from the hose that feeds the vapor separator. If you can't blow through it the housing may be plugged. If that seems OK check to see what kind of pressure is getting to the filter. If it's too low one of your downstream pumps is not working up to par.

ok I will go outside an try that , if i do have to change the pumps , they seem pretty easy to change ( a few bolts right to the side ....) would you happen to know any part #'s for them because the seporater and the first pump with inline filter have the same #'s on them .

first i will go try to blow anyways , the new seperator i have is a quicksilver , the numbers are the same except for the last one , the old one is -2 and the new one is -5 , but they look the exact same and when i gave the parts guy that number , this is what he gave me ....... wonder if you know anything about that

ps. sorry i couldnt get back to you earlier this week , I wasnt able to get on the forum in the last few days , the luck never ends ....

Thanks Matt
 
ok , i went out and took the hose and seperater off , i blew thru the hose , and that was clear and good , then i blew thru the connection with the drain plug out , and couldnt blow thru , do i need compressed air or is my mouth what you were talking about

any who i think thats rules out the pumps and if there is a blockage , how can i check that ??
 
Ok , i went out and found the needle and moved it around , it moves but with some resistence... shoul it move without pulling down on the black plastic needle ( smaller than a tiny nail i hope its the right piece??)

i sprayed some wd40 around it but it still stays in the up position ,

if i am on the right track , is there a way to make it move without resistance , and if i need a new piece , how do i change it ??

Thanks again , i think we are gonna get it .......

The needle should drop on it's own. If you have to pull down on it, it is sticking. To get the float off there are two different styles that your engine may use (there was an early and late production style). There may be a screw that holds the gasket and float assembly to the top of the vapor separator, or you may have to just slide out the float pivot pin.

Pull it all apart and pull the needle right out. Have a good look for any corrosion or dirt in the seat. If there is try to clean it with some carb cleaner and a small wire brush or a toothbrush. While you have it apart make sure you can blow through it with the needle out.

Check out the picture in the parts link that I posted for an idea of what everything looks like.

Aaron:cheers:
 
the float assembly came off no problem , its was just a pin , there was a tiny metal clamp just under where the pin comes down , is that the seat ??

also is there more than just the needle that moves , because that is all i found that moved up and down ........ perhaps the piece the needle is in is supposed to move as well and that is what is siezed ??
 
The only thing that should move is the needle. Can you blow through it now that you have the needle out ??
 
ok , i took the needle out again and blew into the hose connection that connects to the hose coming from the seperater .... i hope i am blowing into the right one .......

anyways even with the needle out , i still cant get any air thru

Check your PM.
 
Hey ,

Good news I got the boat started .......... it was the pin that was stuck in the up position .

I havent taken it to the lake yet , but it does seem to be running a little rich .

is there anything i can do for that ??

thanks again for your help.

Matt
 
That's awesome to hear. Told ya they were not that bad. Just have to narrow it down one thing at a time. As for running rich, if the needle is now stuck in the down position it will do that.

Order yourself a new needle, clean the passage with a pipe cleaner or something similar and you should be like new.

Aaron:cheers:
 
Matt - did you replace the pin or just clean it up. I had the same thing happen a few weeks ago. Took apart the vapor seperator to get to the float, needle and pin. Worked like a charm until...

I think the same thing is happening again. I gotta take it all apart again. Let me know if did anything particular to stop the problem from happening. It's a real PITA to be doing this every couple weeks.

Thanks

Chris
