Hi, my Dad's just bought a 2.2dti omega estate, which went fine for a couple of weeks, now just turns over and won't start. Everything else looks fine, no fault codes etc, just sounds like theres no diesel getting to the cylinders. Was told that there is a pump in the tank that should start up when you turn the ignition on, but can't hear any noise from that area. Does this sound accurate? Took the boot carpet up, took off an inspection plate, and found 5"ish round bit with fuel flow and return, and four pin connector, but all looking a bit rusty so didn't want to disturb without a bit of advice. Cheers

There's no pump in the tank. The only pump a 2.2 diesel has is the injector pump.
Its quite common on these for the fuel to drain back to the tank if there is an air leak in the fuel return pipes, injector seals or leaking fuel filter.

first thing to check is glow plugs :y

Wouldn't have thought the glow plugs would have lit up today, its not been that cold. Could be wrong tho ::)

Worth a try, but I've never had a diesel that wouldn't start eventually even if all the glow plugs have had it. Nor one with an air leak that wouldn't pump it through eventually. We've tried over and over to get it going incase it was fuel leaked back (parked nose up on hill), but spose we'll have to tow it onto the flat and have a go. Should the fuel pump start with just the ignition on to pressurise the pipes?

It takes forever cranking the engine to get the fuel pumped through. I have fitted a bulb pump to mine to hand pump it after i've changed the fuel filter.

the 2.2dti doesnt have a fuel pump just an injector pump which is driven by the engine turning, so you have got to crank the engine to pump the fuel , i`ve changed fuel filters on both the vectra and omega 2.2 dti and each time had to crank engine for ages to get it to start,
i know years ago to get a diesel to start i`ve sprayed easy start into the air intake and that would get it to fire up, not sure if its the right thing to do with modern diesel engines tho.

You can still do it but make sure the glow plug light has gone out first ::)

Cheers, might be getting confused, was told it was a common rail diesel, take it that its not if the injection pump is run off the crank. Can't find a haynes for it either, what manual would you recommend?

Sure Kevin Wood mentioned it was a bit parky this morning. "rather Ice, bugger" I believe was the polite version....

Was lovely here in Norfolk, out in T-shirt til about 2, then started getting cold.
Has anyone tried anything like http://www.whichmanuals.com/Cars/Vauxhall/Vauxhall-Omega-Workshop-Manual.html?osCsid=f24298a90d4b0850d4c0c555c6a0fdb0, what do you think?

Sounds suspiciously like a dodgy copy of the GM TIS to me which is copyrighted to General Motors and costs a hell of a lot more that £20 but gets pirated on a certain auction site for a hell of a lot less.

Is there a haynes for anything that has the 2.2dti in it?
-
OK Wayne I used to maintain a fleet of taxi's and this was a common problem,it is probably the injector seals.
There are 2 easy ways to check ...parkthe car nose down on a hill overnite and you will probably find it will start in the morning as the fuel won't run back uphill,second test take out the fuel filter and look for a section of black on the bottom,this is engine oil as when the fuel runs back it sucks a little engine oil with it.
If these checks prove possative change your injector seals.
BTW they can be changed without removing the camshaft.
Hope this helps,any ? just ask.

had vectra and zafira 2.2dti being a pain after filters etc and both had to be towed for about half a mile before they would fire up!!! :y
-
oh yes
the haynes vectra one, mar 1999-may 2002
hope that helps

Result, more or less! Can of diesel on bonnet, clear line to injector pump, after a bit of cranking, engine stared and ran, not probs. Drove onto flat area, (was nose up on steep drive) reconnected fuel line, revved nuts off for a bit, and starts and runs no problem. What do you reckon? Injectors not shutting or something? Can you fit a non return valve in the fuel line? Whats the best method of finding air leak in fuel line?
I think the thing that was confusing the old man was in the handbook there is a picture of a car with a spanner through it, that should come on for a couple of secs when ignition is turned on, and relates to the immobiliser, engine electrics and exhaust electris I think, but this doesn't light up, so thought immob was having a fault. No electric on engine as such, and none on exhaust, so maybe this one isn't used? Thank you all for all the suggestions and help, he's a happy bunny again!

I reckon if you park it nose UP on the drive tonight it wont start in the morning,re my first reply.
I strongly suggest you have a quick look at the fuel filter and check for oil stain re my first reply.
You can't carry a can of fuel with you all the time,can you?
-
Its been moved to a flat part of the drive, and is starting no problem at the mo. The can was just to get it going and get it up the drive. Sorry, didn't read all of your post properly, or didn't take it all in anyway, but I'm sure you're spot on. Will check the filter, and go from there. The seals you refer to, are they part of the injector, so the whole injector needs replacing?

You can buy just the seals ;)
-
Before replaceing the injector seals, replace the bleed off pipes and T pieces. Its an easier and cheaper job, you never know your luck, it might just be them ;)

Oil in the fuel filter will give the game away ::)
