Help, I've got a dead veccy!!

Owned car for 7 months and never had a starting problem. Set off for work this morning, got 10 minutes down the road and it just cut out. No warning...just died and wont restart.

Called the AA and he did the usual very basic checks and towed me back home suggesting it was a faulty fuel pressure regulator (but admitted he wasnt sure)

Can anyone help to confirm this is the fault before i go spending my hard earned cash only to find i still have the problem.

Leak off pipes seem to be a common fault with diesels but would of thought i'd have got rough running before the shut down! Checked them anyway.
I am scared it will be the pump and hoping someone will say...ooooh try this or try that!
Please god of vehicles, make it be a fuse or relay!!
Any help greatly appreciated and if it IS the pump, donations greatly accepted!!!!!!

Yep, they were a bit troublesome, think they've been improved since then, but it could be vacuum sensors , split pipes, clogged filters, air leaks, the list goes on, get it to a good diesel experts, they should find the problem:Cool2:

Latest update:
Just been out to the car to check if car has got fuel regulator in the tank. Only 2 wires and 2 pipes go to it. Unplugging the multi plug makes the gauge drop so i know thats the sender side. No other wires at all!
Unplugged both pipes that come direct from/to the tank one at a time and cranked it over. Nothing came out of the pipes OR the tank!
Also drained the filter housing, resealed and then cranked again....expecting the filter housing to fill up....Nothing!
Not 100% sure how things work but would have thought that even if the injection pump had died i should of still had fuel pumped out of the tank or pumped to the filter!
Any ideas?

Since you've already checked the spill pipes this is kindof moot but I suppose that a large enough leak would prevent the pump from drawing fuel. It wouldn't hurt to cap off the spill pipe connector at the pump's banjo just to be 100% sure.

As you've probably already gathered, any air leak has the potential to upset fuelling. To eliminate as much fuel pipework as possible, unclip the fuel supply pipe at the filter and try running the pump straight from a can of clean diesel. You can slacken the 'injector' unions at the cylinder head and crank the engine a little to bleed it quicker if you want.

Not 100% sure how things work but would have thought that even if the injection pump had died i should of still had fuel pumped out of the tank or pumped to the filter!
The Vectra doesn't have a separate lift pump, it's all done by the injector pump.

Good luck and let us know how you get on.

ok, ran pipe into clean diesel, blocked off spill pipe from pump,cracked off the injectors and cranked her over ( funny how cars are women aint it?...not mentioning anything to do with causing us hassle.!!...cheryl from other dead vectra thread excluded!!)...injectors one, two and four had fuel coming out of them....injector three however....nothing....not a dribble!
Does this help shed any light on the subject for anyone?
If i had a dead injector, would the car still run...all be it a bit lumpy? or would a dead injector cause the non starting/ non running?

Dead veccy now had diagnostic check and a 1630 fault code was found. (Fuel injection current circuit low voltage). Before i spend vast amounts of money and mutilated knuckles changing the pump, can anyone suggest anything else. Bearing in mind no EML light came on at all.
Kinda weird how pipe to injector 3 didnt even dribble when cracked off and cranked!
Would it help putting clear leak off pipes and fuel pump feed pipes? ie, be able to see if fuel is tracking back to the tank? (air ingress)
Also kinda spooky how my now dead veccy was scarily close to the 20ltr mark when it died!
IF i HAVE to change the pump, do i have to change it for like for like or are certain pumps interchangable?
Really have my doubts about it being the pump as car has done less than 59k miles!!
Any help, advice would be GREATLY appreciated. Its wifes birthday soon and dont want to be working on the car on her birthday weekend......im sure you blokes will appreciate the grief i'd get!!!

nope. trying to find a second hand pump still. Spill pipes and injector seals vacuum pressure tested , 20 litre (myth) tried and failed!!!

Spoke to 20 year serving vauxhall tech and he has NEVER heard of the 20 litre mumbo jumbo!

Final conclusion...its the pump. Makes me think that changing the pump on yours was your problem and not the 20 litre syndrome!

I have tried every trick, hint, tip and diagnostic test going and it all points back to the pump!

I need to find a scrap yard like your local, cos you obviously have god on your side by finding an EXACT matched pump the very same day you wanted one! (Whats there number? maybe my luck will be as amazing as yours!)

Try 02088854165 In Tottenham London N17 they had them at a resonable price.

The 20 Litre bears out as there are numerous posts here referencing the 20 ltr thing.

Mumbo jumbo or not it worked for me.

Cal, When mine wouldnt start it eventually turned out to be the spill off pipes. No sign of a leak from them but thats what it was. Yes I see they have been vacuum tested but for the sake of £5 I would replace them first. Are they the furry type of pipe or the later solid rubber ones.
These and the injector seals are the common faults as you no doubt know but it must be very rare for a pump to go at this low mileage.
If the spill pipes don't do the trick I would suggest as someone else has that you get a diesel specialist (Bosch?) before you replace the pump.
Good Luck

Thanks wemyss, spill pipes were replaced dude and injector seals checked. After all the tests i have done and diagnostic checks and speaking to vauxhall techies. I KNOW its the pump, if im honest all the tests where just to put my own mind at rest before unleashing the sky high price for a pump. Not even gonna go second hand, especially as the new one direct from bosch is only £75 quid dearer than the cheapest second hand or recon ones i'd found! And they DO HAVE TO BE EXACT MATCHES. None of this fingers crossed b*ll*x waiting for scrap yards to call me only to find the pump is different to mine!
Thanks for the input anyway bud, any help or advice is always appreciated!

dont they have to be matched to the ecu too due to the immobiser?
Yes, sometimes. Cheryl on here recently replaced her '4003 pump with one from a scrappy without a hitch. I wonder whether it's just cars that have factory immobilisers fitted that need Tech2'ing or maybe it's down to the pump number?

Sounds expensive! :( Out of curiousity, what are you going to be paying for a new pump? For reference I should point out that you can get a repair and a full mechanical recon on your current pump for around the £600 mark incl. 1 year's unlimited warranty.

The pump wasnt the problem.

The car is still dying at 20 litres on the gauge and theres 20 litres actually in the tank I syphoned off at the fuel filter.

The pump came off a runnning vectra and was still warm lol, it was just over the red on the fuel gauge.

The old pump is back on and I have a jerry can in the back incase I get caught out at the 20 lite mark.

Spoke to a vauxhall specialist and he has told me the DONT need to be matched to the ECU but DO need to be the same number.

Have to wonder why anyone would take the pump off AGAIN if the car was running fine?

So I could double check the original pump WAS ok, and it is, changing the fuel pump isnt a hard job if you have the right tools for it. 3 hours off and on again. and faster once you have done one before. I also did it to help opthers here that may be having these problems, rather than go for a pump straight away check other areas first.

Also Im selling the pump I bought from the breakers.
