Advice please chaps,
My local garage has just fitted a new thermostat-temp sensor-injector top seal-4x leak off pipes-one way valve primer bulb-oil and filter change and have found that they are having a devil of a job starting the car and reckon that the fuel pump may be tired or whatever.
Anyway they have suggested a relatively cheap fix involving fitting a lift pump to the fuel line somewhere under the car and reckon that should do the job.
Said its an easy and fairly quick job and the pump itself is only around £30-40.
I have used this garage on many occasions and have always found them helpful and fair,but just wondered if this sounds a good idea, as Vauxhall didnt fit one as standard on the 2.2DTi.
As usual any ideas very gratefuly received.

There not bleeding the system correctly, the prescribed method for a VP44 is to apply a vacuum to draw the fuel through air and all.

Excessive cranking without bleeding the system will goose the injector pump.........lets hope they have not done this

Thank you Mark, I have just rung the garage and informed them of your advice, and it seems the guy who is working on it was with a local vauxhall dealer for 20 years and is used to Omegas.
They had a conversation and he has apparently already done what you advised, so they have located a lift pump and seem fairly confident it should do the job.
What do you think?

Sounds like they can't find the fault so are "bodging" (although not a bad one in the grand scheme of things) it to get it sorted. Not sure if I'd go that way or not

[TheBoy]

Sounds like a bleeding issue. If they come back saying the main injection pump has failed, then they caused it.  Running the VP44 dry will damage it mechanically and electronically, and will not be economically viable to fix.

Alarm bells always ring when I hear "Vauxhall trained mechanic"

Hmm, hope its a low pressure pump! seen a dt fitted with a "lift" pump, and it did nothing but smoke like billyo engine was all over the shop with surging ,drove horribly,turns out whoever fitted the pump had used a high pressure pump instead of low pressure, it was forcing fuel through,as it was running!

Oh gawd elp me, not looking forward to tomorrow now when I go and collect it.

Better get my postcount up smartish as there could be another Omega for sale soon

Thanks for your comments anyhow lads, I suppose its only a car innit.

There is a problem then where air is getting in

So I picked up my car from the garage and it started on the button.
Drove it home and would have sworn it was pulling better and seemed quieter than before.
Next morning it didnt want to start, but once going it was great, definitely more power for some reason qoieter.
Next 2 days the same, reluctant to start but great when going..........UNTIL I was doing 30mph along Brighton seafront and it suddenly decided to go from about 800rpm to MAX revs in an instant accompanied by a huge cloud of smoke.
I put my foot on the clutch and headed for the kerb, pulled up and switched off but the big silver b@gger just kept on going !!!
I had to stall it to stop but it was reluctant even to do that and took several seconds before it finally shuddered to a stop, during which I was enveloped in a massive cloud of blue/grey smoke.
RAC man turns up and I explained it all to him, so he reaches in to switch on the ignition and I advised him against it, but he does it anyway and it starts instantly and goes to maximum revs and once again I am encased in a great cloud of smoke.
He leaps in to the car and switches off ignition to no avail and then tries to stall it, again to no avail until the car edges forwards and rests up against his van, at which point it finally stopped.
At no point did RAC raise the bonnet, but his opinion was that the turbo, or somethig in it broke and the engine was burning the oil from it which is why it would not turn off.
A very scary experience though at the time, although it seems quite amusing now as I type this.
Anyway, as I half expected when I was forced to take this in to the garage in the first place, this car is now only scrap.
Shame I cant advertise on here though

Sounds like the garage that did the job beggared it up big time I'd be having a few words with them.

More directly to the garage that 'fixed' it, do not pass go etc just make it very clear they need to sort it!

[05omegav6]

Indeed, take it back to them... and have words.

Incidentally, what happens if you disconnect the lift pump?

Also, when was oil level checked last?

This behaviour is typical of too much fuel being pumped in, whether from faulty injectors/seal or a n other cause... forcing excess diesel into the sump... this raises the sump level until the engine starts to syphon the sump... it then runs on the sump contents until it either runs out of supply and goes bang, or you stall it...

Not normally an Omega issue, but common on poorly maintained vans...

Drain the sump down, refill correct amount of oil and disconnect lift pump... and try again...

Would offer to look at it but next day off is 30th if that's any use

[Omegatoy]

almost exactly what i was saying, the pump throws to much fuel in, an revs rise to horrific levels,turbo seals let go engine revs faster and faster, rac man should have known better!!

[amazonian]

Well I am not totaly surprised it happened, its why I have been trying to get someone from OOF to do the work, but could not,  so had to go to local garage.
It makes sense what you guys say though, maybe disconnecting the lift pump would sort it, but lord knows what else would need looking at before I dared start it again.
As to the oil level being checked they did an oil and filter change as part of the job so level should have been okay.
Harris K Telemacher,  I have sent you a PM as well but yes the 30th would be a great deal of use if you could manage it

Return it to the garage. They bodged it and caused this, no ifs or buts.
