Can any one help me please. I drive an 02 model Vauxhall Omega 2.2 dti cd estate with about 130000 miles, over the past year has run on a variety of diesel from Tesco, Asda and Siansburys also Shell and Esso and more recently from October onwards Bio-deisel in various blends upto approx 90% bio to mineral fuel. My problem occurred approx 3 weeks ago. At lunch time I came out to the car to make a phone call, using hands free kit in the car, engine running, ticking over to keep both car and phone battery charged. No problem. Came out of work at teatime to go home, car wont start. Called breakdown service, car taken home on tow truck. My local garage think its the fuel injection pump, but now tell me to take the pump out is a major task involving specialist equipment and tools which they dont have. Is this correct or am I being fobbed off? A reconditioned pump has been quoted at £600-£800 depending on exact model. I am wary of committing to a new pump if the cause is something more straightforward. Does anyone have any other suggestions?

so from your experience we should never use biodiesel in the 2,2dti !!! thanx for that

there seems to be alot of us with problems with the dti,
could be a number of things mate,
fuel returning to tank caused by an air leak?
check all spill off pipes for leaking
get codes read with a tech 2
try spraying easy start into air intake while turning over as sometimes this is tge only way i can get mine started, if it does start then maybe the pump is not at fault,
good luck with it as ive had my miggy for 2 odd years and still cant get to the route of the problem on mine!!!!!!!
the pumps are bloody expensive and a pain to get to so id try the cheaper £5 can of easy start first to see if this gets her running.
best of luck and please post how you got on

also there is a company called pb asher who do recon pumps with a big discount for your knackered one if that turns out to be the case

dont know how similar the pumps on these are to a Zafira 2.2?
but on the Zaf, the failue of pumps is caused by heatsoak into the pump which contains soldered joints on the board inside,its causes dry joints,
here is the kicker though single electrical connection pumps can be reapired
double connection  pumps are scrap!!! I believe its because they contain the ecu inside the pump? bummer

how dare you mention a " zafira" in my beloved omega 2.2dti elite post!
and please any mods reading can you pm me an email address so i can send pics of her during various stages of maintenance i undertake on her as i "CAN NOT!" figure out this "wank bucket" sorry photo bucket picture upload thing!
please
 
just wish someone was closer to southampton who could give me a second oppinion on whats wrong with my bloody car! :-/

has the car been started since the brakedown?? park it nose down and see if it starts... open th efuel filter and see if there is diesel in there, probably biodiesel clogged. these are some of my ideeas for now and you can check it with no special tools

[Rich-K]

Thanks for the suggestions and advice regarding my post about the fuel injection pump. The garage have done all the usual checks, filters, fuses, leaks etc, the computer teckie confirmed the fuel injection pump has packed in.  In veiw of the expensive cost of repairs (even with a reconditioned pump), I have reluctantly come to the conclusion that it is not a worthwhile proposition, and so the car is now up sale.
If any readers are interested in buying the car for spares, or restoration project please contact me.

Demand your garage tech2 the car this will show exactly if the pumps at fault.
Don't let them make ,erm well I think! this will cost you money.
If they don't tell them to get stuffed and take the mig to a real mechanic.
As for the price they gave for the pump 600-800 thats the cost of a re-con new cost £1300 upwards.

get a pump from brakers or try to resolder the ecu inside the pump.. that is the main cause they brake down

Why so? I've run my 166k miles 2.2 DTi on Bio for the last feww thousand miles with no adverse effects on the engine performance or fuel pump.

With the colder weather I have mixed 2 litres of petrol for every 100 litres of B100 Bio to stop it gelling and even when the temps dropped to -14 here it started first time and ran perfectly 

[greenfingers 79]

get some pics up and a price for the car

[Rich-K]

To Graceland thanks for your comments re Bio diesel, I too have run on Bio for several thousand miles, and had no trouble starting during the coldest weather when we had lows of -14. I will try to sort some pics as soon as I can.

run on biodiesel for 20-30 thousand miles and then we will talk.. you ran it for just a few thousand miles and you say all is ok . you make economies on one side but you loose when you have to change th efuel pump, or like rich-k the entire car . on these pumps the main reason they fail is the ecu, but that can be resolved at a specialist(mobile phone servce) wich resolders the wires in it. the second reeason they fail is mechanicly and that is due to runiing the car until its tank is dry. the fuel pump uses diesel fuel to lubricate so when runing on air the lubrication doesn't happend. i would never use bio and risk damaging my car

I'm no virgin to Biodiesel - I've used it in all my DERV  motors on in the last 5 years and never had an issue yet.

My 03 reg L200 did over 50k on Bio and never had any problems at all - regular oil changes and fuel filter changes play a big part in keeping an engine happy when on B100
