sprinter diesel running on

hi people, firstly i would just like to say hello to everyone
ive just bought a 97 mercedes sprinter 208d swb
im having a few problems with it,
first and foremost the engine wont shut off
second is the door locks dont seem to work
ive had a look thru a few problems from other members but none of these were specific sprinter problems
i have replaced the shut off valve on top of the fuel pump today (what a pain in the ...)
but still no improvement, i read on another post that the door locks run from the same vacuum system as the shut off pump on the back of the ignition switch,
do i have the same system on the sprinter, if i do then i think the problem will be solved, if i can find out where im losing the vacuum from,
any help would be appreciated
just to recap, my ignition switch is really stiff, hard to turn and stops on each click, the door locks turn a little but dont work so i cant lock it, and the engine wont shut down when i turn the ignition switch off
thanx carl

These vans didnt come here until a few years ago so no one is going to have much expirience with the older models. I do not believe your engine was imported either. Might be better served to post on the UK forum.

Anyway, it's a 2.3L 5cly right? Is it a CDI?

Are there any codes present?

I'm pretty certain yours is not vacuum controlled. It is too new. Is the check engine light lit up?

The shutoff valve should be an electrohydralic solenoid located on the side of the IP. It is a black plastic valve with fuel lines attached. When you say you replaced the shut off valve are you referring to a "push button" type kill switch located on top of the fuel filter housing or the aforementioned solenoid?

no, this is a white plastic ufo shaped unit that bolts on with 2 bolts, onto the top of the ip
it has a spring inside and a vacuum pipe on top, the vacuum lifts the rod going down and pulls the fuel position either up or down depending on the vacuum, im not usre where the vacuum is created, i do know that somebody tried to steal the van and they damaged the ignition because ive put it all back together today, the surround plastics, and some of them were snapped, which is why im assuming its the same system
cheers carl

OK, that does sound vacuum controled. I guess the newer IP's dont make it into the the trucks, only cars.

You should look at the ign and make certain you dont have a vacuum leak in the line going to the shut off. Likely problem if someone cracked open the ign.

Some folks on the diesel forum have disconnected that line and shut the hood with it sticking out a few inches (10cm) so they can apply suction to it by mouth. Means they dont have to open the hood each time they need to shut it down. Must look strange to passersby when they bend down and appear to give the car an affectionate lingering kiss....
