Heres how to prime your 2.0d with minimum amount of hassle - (5minutes). e.g you've changed the fuel filter yourself and the car now won't start.

Items:

Hand primer
£4.99 from ebay - search for "diesel primer"


Bit of hose:
£few quid from halfords etc


--------------------------------------------------------------------


1) Ensure input hoses are now connected (if you've changed your fuel filter, FILL it with diesel first!!). You now need to disconnect the green return pipe as cirlced below:



2) Connect the hose you purchased onto the priming tool - onto the black end in this case (it sucks in through here)

3) Connect the hose onto the green return pipe you've just disconnected.

4) You now need to pump (maybe 10 times) until the pump ball stops expanding and remains squashed in your hand (this means it's sucked the fuel through as much as it can, and is only now able to hold the fuel in place using the vaccum it's created).

5) Get somone to crank the car over. Took 10 seconds for mine to start.

6) once it starts. QUICKLY re-connect the green pipe. And thats it. your done! No need for any autostart spray! Go take it for a drive.

The primer ball being unable to expand is the same effect as putting your tongue over a drinking straw and stops the drink going back into your cup.

Total time > 5mins

Hi there,

would it be possible to repost the pictures as I am not able to see them for some reason that I dont understand.

Many thanks

Some days ago I got in the in my Volvo S40 2.0D as usual. I started the engine with no problems but maybe 5 seconds later it just stopped. I tried several times to start it again but without any success.

I noticed that there is a lot of air in the fuel lines. If the line after the fuel filter is 30 centimeters, the first and the last 5 cm of it were just air. I bought this "diesel primer" and tried to prime the system but with no success - after the second squeeze the pump was not able to do anymore. I tried to start the engine some more times and now just after the fuel filter the line is full with diesel but the last five are still air and I cannot start the engine.

Before this day I haven't any problems regarding the starting or the work of the engine.

Did you try towing it as suggested?

Good luck and update us.

LOL, as I wrote earlier a friend of mine came with the intention to tow my car. I tried to start the engine for a one last time. Event that there was ~10 cm of air inside the fuel lines the engine started after 3-4 seconds!!! :O This happened maybe after 20 tries in the last days! :O Now the car is running as usual.

I suspect another problem but i'll open another thread.

To get rid of the air in the system I tried to use a manual pump as recommended: connected to the green pipe, but after I've pressed it, it stays as is, it's not able to pump any fuel out.

I also tried with a self bleeding (up to 5m) electric fuel pump (connected to the same place), no use of it, it looks like the line must be blocked somewhere between the green pipe and the fuel filter, because I managed to bleed the fuel filter very easily at least.

I have no idea what this could be. The car had been running fine before I let the air in not knowing it this engine was not self priming...

Does anyone have any suggestions? Now it looks like I need to get the car towed to a garage if it can't be sorted.

I appreciate any suggestions

A blockage is highly unlikely so are you sure you're pumping the correct connection?
That said, I thought priming the 2.0 was the same as the 1.6.
Pull the return line, crank the engine until fuel comes out and replace the return.

I really don't know now what to think, this is not self bleeding, so won't really start on it's own. I found the photo bleow using google images, it is exactly the same engine as mine. The blue arrow shows the connection that I unplugged, the pipe on the right side is where I connected the pump to.
I think I will try again once I have recharged the battery (too much cranking...).

Do you know, does cranking opens a valve or is that absolute necessary to get the fuel out?

Luckily local garage came to my house and bled the system. It took a good 5 mins of pumping with an industrial size pump though and even then 4 or 5 cranks to get it fired up.
It's a crap system.
