Oh bugger, it won't start...

[Nonnie]

Recently refitted fuel pump and filter assembly into my tank, no obvious leaks (I know because I have had a fag close by) with the ignition on you can hear the fuel pump running although it sounds as if there is no fuel going through it and the engine does turn over but it won't fire. Checked the orientation of the fuel lines i.e. M and R (thanks Rob - "Robs 24 hour telephone support - love it!") but still no joy. It does sound as if the fuel pump is running dry even though there's 5 litres of fuel in the tank.

Any ideas on what to check now. Been through the workshop manual but have come out clueless.

Help get my baby started. He look so pretty.

hahahahr

its not funny really and i can imagine incredibly annoying


if your certain you have the correct tank line to the correct throttle body connection

and you have the fuel pump connected the correct way round (so its not running in reverse)

disconnect the return line and see if it pisses petrol all over to make sure fuel is getting to the injectors when you prime the tank

[Nonnie]

OK, be right back!

[dunlop0_1]

What's the fags name? LOL.

[bigredduke]

Maybe an airlock in the pipe?

[CK & AK]

Nonnie - hope you get this fixed, AK had the exactly the same prob with a pump that had been out of a tank for quite a while and he has reluctlantly got to replace it as it ran but had no pressure thus no fuel through and so no firing :(
He says tells Rod to to spray some easy start into the airbox and if it fires then the prob is fuel pressure.

I'm certain we have the tank lines the correct way around, the fuel pump connection can only go on one way. When you say disconnect the return line, where do you disconnect it from? At the tank end or where else? All that was disturbed when the tank was removed were the 2 fuel lines, the electrical connection to the pump and the 2 vent lines.

Is there an easy way to check if you have an airlock.

Tried starting it with fuel cap open but nada.

Thank you for waitng up with me this evening! I can tell you it is ****ing freezing in the garage tonight!

Thank you Charlotte. Off to try that now while everybody works on the problem remotely for me!

Love you all

[Nonnie]

Before I try this, should we have done something with the pump before putting it back in? The whole assembly was removed as one from the tank by undoing the 6 flange bolts and simply bolted back in. It was working OK before so we assume that it's still functional. Can definitely hear it running.

[Albie]

I hope I dont have this sort of problem later on. I will follow this with interest. Good luck Nonnie and be positive. Put another jumper on and plenty of tea. Cant wait to see the launch

How long was it dry for Nonnie?

Is it a plastic tank? (prob not)

The duff one we had was out for quite a time - nearly a year, but had been fine in the race bike till then, poxy thing. AK even phoned a couple of mech mates in Ducati dealers, no idea either. AK took it apart - still no probs found..........

[Scotty]

do you know anyone who can suck a golf ball through a hose pipe ?

im all out of ideas :(

uh the return at the tank end is easy-ist to remove to check for fuel flow

[Nonnie]

The pump was out for 2 months. It is a plastic tank.

Going off to undo the return line and see if fuel p1sses all over the place (NO SMOKING)

And Dunlop, not that kind of fag. (My best friend moved to America and wondered why everybody gaped at her when she asked to bum a fag off someone..)

Thanks Albie, have hot chocolate and a fleece, 2 cats, a scarf, some gloves and it hasn't made any difference!

[CK & AK]

Good luck, dont wake the kids at this time of nite or they will be:Furious:


Off line now, will check back in the morning to see how it went :)

[Nonnie]

OK, the bad news is no fuel pumped out of the return line when it was removed at the tank whilst the engine was turned over.

The good news is that I have discovered some mulled cider to keep me warm!

Is there any mileage to undoing the delivery line and seeing if fuel pumps out when the ignition is turned on?

Any other suggestions?

We can now assume the fuel is not getting to the injectors.

[barbican]

With an old car submersible fuel pump I had once, the pump was just not priming itself. In the end a mate blew in the fuel filler, sealing between filler and mouth with his fingers, whilst I cranked the engine - the pressure created in the tank got it all working.

Sounds stupid but quick and easy to try

Good luck

[Nonnie]

OK, we're looking at each other here wondering which one of us is going the hell to do that!

I think after one more mulled cider I could be persuaded!

[slob]

...put some tape round the filler cap to seal it and blow into the breather pipe.
(but mind your fresh paint)

come to think of it, have you tried it with the fuel cap open, just in case you've kinked the breather pipe getting the tank back on and it's not allowing the pump to prime.

[Nonnie]

Do you mean blow into the vent pipe that hangs down at the bottom of the engine?

Whilst starting it or before?

[Nonnie]

We have tried it with the cap opn but nothing, we also tried it with the tank upright so no kinky pipes here.

We turned it over with the return line disconnected and no fuel came out which would suggest the fuel pump is not priming so we will try the breather pipe trick! So off to the garage for us!

If that doesn't work I'm taking Woddy to bed!

[slob]

Do you mean blow into the vent pipe that hangs down at the bottom of the engine?

Whilst starting it or before?

yes(it's a combined drain for the filler neck and tank breather/vent) but pull it up away from the exhaust/engine, so it comes out through the side of the frame.

...whilst turning it over.

[Nonnie]

Thanks Rob, back in a bit!

[Albie]

Its like a baby being born.:biggrin: :biggrin:

[Nonnie]

But no. No births here I'm afraid. We sealed it to the best of our ability and blew like a blowy thing but still no joy.

Thank you all for staying up so late helping me when let's face it, we all ought to be down the pub.

Let's see what tomorrow brings!

Night

[neilbaldry]

i wish you well Nonnie!

[YoungDucS4R]

I had exact same problem with my one year old S4Rs, without having removed the pump from the tank. The bike just suddenly stopped running, luckily very close to home!
The pump could be heard priming when the ignition was switched on but the engine wouldnt fire due to lack of fuel.
The bike was eventually AA'd back to the dealer under warranty.
I was told that it was the first failure of a fuel pump they'd ever experienced!!
Apparently they bench-tested the pump to verify the fault and although it was turning and making all the right noises, it wouldnt pump. In the end they fitted a (very expensive) new one!!
It may be easier to see whats happening if you test-run it on the bench (in a bucket of water???).
Good luck!!

[barbican]

Doesn't say anything helpful in the workshop manual, so if the plumbing is correct, and presssure regulator OK then it should work - sorry for the wild goose chase!

[bigredduke]

I reckon Rod has forgotten to put something back properly. You know what an untidy, messy worker he is. You have all seen the photos that prove it.

[Nonnie]

Rod is currently sitting out there looking at Juan, his head in his hands saying "What have I done? I lovingly put you back together again, made you all pretty and this is what you do to me, how could you? I've created a monster"

We are going to try some more fuel (just in case) and then if that doesn't work, disconnect the delivery line at the tank and see if fuel pumps out when we turn the engine over. Failing that, it'll be a cry of help to an independent Ducati specialist we know.

Yours in despondency

[dlloyduk]

Why not try priming the pump by filling with fuel through the pick up or delivery hose? Worth a try.
It sounds like these pumps have some kind of seal that dries out when left for a while-if any one else is going to leave one standing for a while maybe worth priming the pump and plugging the ends to keep the insides wet, a piece of tube connecting the delivery to the return should do it. :idea:

[Nonnie]

OK back to the garage with that then.

I shall report back!

[retskcid]

If the pump is ok and everything has been put back right it sounds like it needs priming somehow. Didn't they use vasalene (sp?) in the old mechanical pumps years ago to prime them initially?

Just a thought!

Rich

[dlloyduk]

While you are there fill both sides of the pump just to make sure-may save you a trip!

[Nonnie]

Disconnected the delivery line and turned the engine over and nothing comes out whilst cranking. Put another 5 litres in the tank so I am sure the pump is submersed, still hear it running at "key on" but obviously nothing is running through it. I will try and prime it but if I connect a jumper pipe between the delivery and return outlets, since nothing is coming out the delivery side then I cant see anything being fed back into the pump from the return side. As I have checked and double checked everything I am now of the opinion that the pump has failed. Any ideas how much one of these goes for? Looks like the tank is going to have to come off again! :Furious:

[dlloyduk]

Have you tried blasting some fuel down the delivery line?

[bod]

Measure the voltage to the pump when ign on (priming) and when cranking also.
Never had the tank off mine but can you attatch a seperate bit of fuel line to the output of the pump to check the flow rate?
If all is piped up correctly try reverseing the porlarity of the pump briefly this has worked for me on in tank pumps before and borought them back to life!
Before you buy a new pump take it out and bench test it in a washing up bowl or simlar with some water in.

As a smoker myself also would,nt condone smoking near petrol have you ever seen it go up,I presume you like your eyelashes:)

[CK & AK]

Best to call for prices - some dealers are doing the metal tank pumps for just over £100 - tho one priced it up at £400!! :eek: :thumbsdown:

Not al all sure how mucho the plastic tank ones are tho :o

[Albie]

Have you sorted it yet. Whats the score.:confused:

[Nonnie]

Well, the tank has come off again and is currently on its way to Karl Harrisons at Harleston for him to hopefully fix.

I'll let you know later how it goes. Or not.

[benson]

How ees dee pump? (said in bad Italian accent) ees eet pumping yet? I ope so my dears coz you tank is bound to looka da mega bling...

I have no idea why I wrote that in such a foolish fashion but there you have it - I do so hope Juan Pepperami is better.....

[Nonnie]

Grazia bella

xx

[Nonnie]

Well, the prognosis is that the pump has given up. Not enough pressure.

Going to be replaced with a second hand one at £35 instead of new at a hundred and silly something Great British Pounds.

Also a small leak underneath that will be fixed too.

Hopefully Juan will roar again soon.

Big up to Carl in Harleston.

That's what happens after you have children!:eyepopping:

[Nonnie]

That's what happens after you have children!:eyepopping:

To men?

How funny!

[bigredduke]

To men?

How funny!

I just leak from my bank account. Actually, it's more of a haemorrhage.:banghead:

[Nonnie]

I guess I hit the jugular!

[benson]

Now that would pump out at speed!!!

[Nonnie]

He say YES!

Juan has started happily with his new pump. No sign of any leaks. It's the first time I've heard him in months so it's a beautiful moment. I'd like to thank my agent for making all this possible, my husband etc etc

Now I just need some handlebars, some indicators and some mirrors and Bob's my country lane buddie!

One step closer to premiere launching!

[benson]

yehhhhhaaaaaaaaaaaaahhhhhhh! can't wait to see him in all his glory!!!

[Nonnie]

wanna sneak preview???

[benson]

Yeah Yeah Yeah!!!!!

[benson]

I will just go get my shades!!!!

[Nonnie]

Just charging the camera!

[benson]

I'm just off out for supper - can't wait to see it when I get back - are you in lurve?????

[Nonnie]

yep yep yep!

I wish I was going out for supper. Instead I had to make my own. Yah boo sucks.

[benson]

I had a very nice supper too thank you - now where is the photo????:thumbsup: :thumbsup: :thumbsup:

[gary tompkins]

Ok - where's the bloody pictures!!! :hissy:

[Albie]

I was led to believe its going to be a video

[Nonnie]

It will be. I was just teasing! I might stick up a piccie later of some obscure part but the true launch needs to wait until the rest of the bike gets here!

[kaysee]

Big up to Carl in Harleston.


why did I read that as a big up to Charlton Heston:confused:
