Fuel Pump

[Dale]

Hi guys,
I had a small problem on Sunday with my busa. I went for a short ride in the arvo and she conked out. It wouldn't rev (just coughed and spluttered) to the point where I turned it around to head for home and it stopped completely. I trailered it into my local mechanic, who was saying today, that it looks like the fuel pump. I was curious if this was a common(ish) sort of a problem or is my mechanic having a lend of me because he cant find the real issue. Any feedback would be appreciated ..
Thanks
Dale

Hi, Dale.

I've seen a few threads like this on the .org, so it doesn't seem to be uncommon.

Dale is the F1 light on ? When you turn key on with kill on can you hear the pump ?
When it stopped would it re start ?
My biggest concern would be the statement "it looks like the fuel pump" Is he guessing or has he tested for pressure and volume ?
He should really know if it is or not, unless the statement he made was just at a passing glance as you dropped it off in that case it's fair call at that point.
There is many things that can cause the prob any more info would help.

Hi Pete,
To be honest, I wasn't really looking at the F1 light but I could definitely hear the pump (although it did seem to go for an abnormally long time) when I turned the key on. It did fire once, but all it would really do was wind over. In my mechanic's defence, his statement was made after a quick glance. When I spoke to him thisarvo he said he had the battery on charge and would have a good look in the morning. I'll let you know more tomorrow ..
Cheers .. Dale

Remeber the dramas I had all those years back Pete?
Turned out to be a clagged fuel filter that is housed in the fuel tank.
My problem was fuel starvation over 7000 revs in top gear. Most will never encounter this problem!
Maj being the top bloke he is posted me a replacement fuel filter and it fixed the problem. (Price one from the Suzi dealer! )
I hope you sort your problem. Shit like this is frustrating.

Hey Phil ..................... I do remember indeed. Hope alls good with the family ? Still riding that pushie a million K's a week and I'll bet your bike is still as spotless now as it was then.
Oh and how's the snowy haired fella doing ? Still telling pricks to get of his lawn
You will have to get up to sunny Qld some time for a holiday and will take you for a spin around Fraser Is in the beach buggy ................ welcome anytime at the Glenwood Hilton mate.
Cheers
Dale apologies for the thread crash .................. let us know how you go tomorrow ? Have second hand pump and filter here I think also.

I assume from the avatar photo it's an '01 ?? external pump??
If so, Go back thru the old posts, there are 8 filters and strainers. Check and clean them all. All are easy execpt splitting that pump with the dodgy orings. If I can do it, anyone can.

I ended up chucking the internal filter and cutting out the internal screen out of the pump so I don't have to split it anymore, and I added an inline filter which is cheap and easy to replace. Bike is 11 years old, original pump still going fine.

Check these before you replace the pump.

screen on the outside of pump (undo phillipshead to reveal under vacuum thingy) my bet! (you can get to it without taking the pump out too!)
screen inside the pump
paper filter inside the pump (fckn expensive to replace)
screen in the tank
screen on each injector (x4) (have alway been clear for me)

If it's an internal pump then I know nuthin'

Your spot on with that info Ward ,but I think it's only the 99 & 2000 that had the external pump .2001 internal, I Think .So I'm in the same boat ,I Know nuthin .

[Maj]

You know enough Greeny , 01 is internal.

Phil yours was one of the first i had seen with the filter probs,not an uncommon thing since then, and understanding better now why Suzuki sell the filter and pump as a set,
By the time you notice your filter is blocked, it has been putting the pump under a lot of strain for quite a while , and this wears the pump out quicker . a replacement or cleaning of the filter may not totally fix the issue but probably will bring the flow and pressure into spec for a while .

Pete,
Got my bike back today (going), but I cant say that I am brimming with confidence. Gary, my mechanic was pretty honest in the fact that he really wasn't sure what they had fixed. Apparently they pulled the pump apart and cleaned / reassembled and the bike started. He did say the regulator wasn't on when the pump came out ?? .. could this be right ? I'm a cnc machinist not a mechanic . I'm not complaining, he only charged me an hours labour and it IS going. What would you suggest I do now ? .. See how it goes ? or buy a new one ?? or get that one off you and swap them over ???. I am going to Tathra, so I'd hate it to break down while I was away. I would like to bring the bike up to you eventually .. maybe early in the new year, for a decent service / tune, but we can organise that later.
Let me know your thoughts ..
Thanks again .. Dale

Thanks everyone for your input. Bike is going .. how reliably, I'm not sure. Fingers crossed .. All will be good for Tathra
Cheers
Dale

Dale if the fuel reg wasn't on or in it's place then that would be your problem as the pump would simply be cycling the fuel thru itself into the tank. ie no regulator to regulate the pressure. So I would say if he has fitted it all back together correctly then you shouldn't have any probs. Note here if that was the cause of the problem. I haven't seen that fault myself but if for some reason the fuel reg had become dislodged from its correct position would certianly cause the problem you had. He does sound reasonable as his cost to you appears pretty fair.
As for tune and service some time no problem at all ................. simply give me a yell when time suits.
Cheers
