    Default Another 3.0 v6 fuel pump

    I posted on here a couple of months ago asking for help in diagnosis of power loss to my Signum - you guy's were absolutely bang on BTW.

    It finally died on me on tuesday and went into Vx for diagnosis and repair - sure enough SCV failure was diagnosed and a bill for £937 was what i was facing (including a replacement timing belt as this would have to come off to get to the SCV's apparently).

    Got a call yesterday to say having stripped the car down to get to the SCV's, they had found there was play in the fuel pump shaft and therefore a new pump is required at a cost of £1557 plus vat - reconditioning not an option when there is play in the shaft they said ??

    When i enquired about the total cost of works the reply i got was "add the 2 amounts together" (£2766 total) - I questioned this as I thought the SCV's were part of the fuel pump and if the pump was being replaced then even though I would incur the same labour costs i would be saving on the price of the SCV's - I was told that the SCV's are on the fuel pump inlet manifold and not part of the pump itself??

    I know i am clutching at straws here but is the above info I have been given correct regards it being impossible to recondition the pump and the SCV's not being part of a new pump?

    Don't know about the reconditioning aspect, but here's what I belive to be the fuel pump from the 3.0 - the green and red parts on the end are the SCV's. I'd say you were being taken for a ride as the largest part of the cost of the SCV's is taking hte pump out to get to them in the first place mate...

    It could be true. You can't just replace the SCV's to no end. The fuel pump itself can fail too. If this is the first time you're experiencing fuel pump problems i.e. SCV problems, the fuel pump internals are still OK. Good luck mate!

    When I saw "Another 3.0 v6 fuel pump" and Post by Penfold101...It thought your 3.0 broke down mate :P

    I agree, the pump could be shot or not, but simply adding up the costs for the two jobs is the part I'm disagreeing with mate - if they replace the pump then it's jsut the cost of the SCV's themselves on top of that...

    Which you'd know enough about yourself...

    And no, there's nothing wrong with mine - on it's first tank of lubricated fuel and running nicely thankyou...

    Assuming this is a VX dealership, then once they have removed the cambelt they recommend replacing it (that's standard for any such job)
    Given the cambelt itself is less than £25, I wouldn't even question that (ask for the old one back, the cambelt kit is NOT required so check the invoice)

    I've had a fuel pump input shaft fail before
    I took the fuel pump for reconditioning myself to a diesel specialist as the dealership (Peugeot) said it couldn't be done
    That cost me £400 (probably nearer £600 now)
    However, the fuel pump was never right after that, and I sold the car

    Personally, I would go for the new fuel pump and ask for the old one back (sealed up in a bag to prevent spillage)
    You could then store this for future use and/or have it refurbished by a diesel specialist (but they too may say it's not worth it) or they may even buy it off you for spares

    Finally, your new fuel pump should already have two SCV (it depends on how it is shipped)
    However, if they are not then the replacements will be the "upgraded" version, which is about £130 for the pair

    £3000 is a lot when you consider it is JUST the fuel pump
    The main issue is where it is located in the engine
    Normally they are quite easy to get to

    The final alternative is to make arrangements to dispose of the car as trade-in, most dealerships will do this
    However, taking £3000 off a car worth probably less than £5000 does not make financial sense
    Different if the car was worth less than £3000, I'd just say "scrap" and forget the repair

    Thanks for the input folks, it's much appreciated.

    Regards the pump - it's being replaced so I'll have to assume it is shot but following the advice you've all given I shall not be leaving the dealership without it

    It is a crazy price for a part (let alone where it must be for the labour charge it incurs), I know teams of designers toiled for months on it's design, special robots milled the parts to infinitesimally fine tollerances and finally the small volume manufactured bringing it's value up still further - but christ on a bike it's just a blinking pump, if it's going to break why didn't they just make it cheap and in a reasonable place to change it!

    I would have told them to scrap it if I hadn't asked them to start work on the SCV's and the fuel pump failure was diagnosed when they got to it - which is fair enough, as you cant see the play on the shaft before you get to it (i think??).

    Looks like me and my Signum will be together for a while longer as there is no way i can aford to part with it now (keeps fingers crossed for protection from future money pit problems of DMF. turbo and clutch failures)

    That is very interesting as I know they are charging me for the kit at £271 on top.

    Any suggestions on how I should go about disputing it? I can see myself saying it's not required and them looking at me like i have 3 heads and responding in their best "we are the main dealer how can you question us" tone

    My next car will not be a Vauxhall

    tell them you only want the belt fitting if they fit a kit and try to chatge you for it tell them its unauthorised repairs done off there own back and your not paying it.
    plus tell them if they want to recover "their" property (rest of the kit) they will have to hire you an equivelent car for the duration lol

    As I mentioned above, parts liable to wear and tear are recommended for replacement
    The cambelt is one such component
    However, the tensioner and two rollers would not be

    Has the cambelt been changed before, and what mileage is the engine on?
    The interval is 100K miles / 10 years
    If the cambelt was due within 30K miles / 2 years then I would leave it

    Equally, if it was a warranty claim only the cambelt would be paid for by Sureguard, they would not pay for the cambelt kit
    I had the same occur on a water pump failure on my Vectra B, just after a cambelt change (including both rollers)
    The dealership agreed a cambelt kit was not neccesary after I asked what they work they planned

    Ironically, the engine on this car is not a Vauxhall, it's an Isuzu, and that is one reason I chose it
    My Vectra B was a 2.0 (X20XEV) and after 70K miles developed an intermittent fault that was never resolved
    A few other relatives have had VX Ecotec engines, they are woefully unreliable
    The disadvantage with Isuzu engines (as with any diesel) is they are expensive to repair
    However, once the car is out of warranty you can save several hundred pounds by finding a local diesel specialist; book the car in for two services, one for the Vauxhall bits, and then your diesel specialist for the engine
