Any diesel mechanics about?
As title , bit of help required
First time ever ran out of fuel in a vivaro , stuck a can in it and tried to fire it back up........shouldn't of bothered killed the battery off
Managed to tow the piece of...... Back home , thought 'maybe just air locked'
Cracked nuts to the injectors and primed it up at the side of the filter
Van started first turn
**** then cut out.......did same again and tried revving it up , wouldn't rev past 25/3000 rpms....then cut straight back out
Won't even attempt to fire without manually pumping the primer and then it will cut back out
Tbh I'm not sure if I actually ran out of fuel or it just died....I remember seeing fuel light on but sure when it died it just did that....no splutter
It's a 1.9di vivaro btw
Any 'useful' info would be much appreciated

Dont they run the bosch high pressure pump ?? i would start by removing fuel filter and checking for small metal particles inside ..
any check engine light on ?? Could be crank sensor or a number of things , egr block up on them also , and airflow meters are really common fault ..

I look after a fleet of 50 of these....
If you prime the diesel correctly by pumping the priming bubble they will run without a problem,there is no undoing of nuts or injectors to prime fuel..
If you have cracked the injectors and the high pressure pump is working correctly,then you have probably eroded the injector base/pipe unions...The pump works at such a high pressure,it will easily blow steel/cast away...
First job is diagnostics..
Crank sensors are very common.... Will stop the van in in tracks and wont restart...
Fuel pressure... Can be high pressure pump,or injector blown which will drop pressure in fuel rail..If the rail pressure sensor see's low pressure it will not start..
Leak off test of all injectors frst to see if any obvious signs of leak back..
If not suspect high pressure pump if getting fuel pressure fault codes...

1.9's should have a manual prime on the fuel filter..
Oh....ALi B,you deleted your post!!......lol....

If the van runs when hand primed, suggests the pump / injection side is ok..
(i havant got my autodata manual on this pc, so cant check)
its would appear that the lift / primer side is nok..
running thorugh the basics....
What is the method of getting fuel from the tank to the injector pump?
1) In tank primer pump?
2) External lift pump
3) Internal & external lift pump?
4) lift pump combined with injector pump?
Working on the basic combustion cycle
1) Suck ---
2) Squeeze
3) Bang
4) Blow
you satisfy 2-4 as the unit runs when manually primed...
So you either work from the fuel pump back to find the fault, or from the tank forward.
Daft question... BUT!!!
When was the last time the fuel filer was changed/ drained? it could be a blocked filter.

Loads of people have said to change the filter....going to try and get one later , I can manage that job , looks like 1 torx bolt and job done
Also advised to fill it full of fresh diesel aswel when fitting the new one
If all that fails it's getting dragged to my mechanics place tonight
Don't mind breaking the cars but the van is the only thing that earns me money

Sorry Mart...
But the rules dont really apply on a high pressure diesels..
The van can run with bad pump and/or injectors but will not achieve required high pressure..(due to leak off or bad/worn HP pump gears)...

Your prolly right... as i said, i dont have my autodata discs on this laptop, so couldnt comment...

Did it have any metal in the filter case ?
Its doubtful really as they dont really break the faces off the pump face..
Like i said in the PM Andy,see what fault codes are before anything..Hopefully it will just be a crank sensor
If fuel pressure codes come up then do injector leak off test,if all ok suspect HP pump..
Edit...
If your mechanic has a machine that will read live data that measures fuel pressure in the common rail,i can tell him how to definatively test whether its the HP pump...

Just got to my autodata cd's ...
you did check that the fuel cut off inertia switch had not been activiated / tripped ??
This can effectivly stop anything from running lol
Accodring to what i can see there is also a secondary lift pump which appears to be in the tank ...
Also dead Fuel pump relays can also have the same symptoms

Tried that.....saw a big bubble on the pipe out of the filter down to the pump....took the pipe off at the pump side to get it full of diesel
Just had a kid call round and read it on a snap on reader....came up with a heater problem.....his vivaro has just done the same , ran perfect this morning, changed cam belt and it won't start....he's getting same fault up on reader as mine......he seems to think crank sensor
