Hi folks, 
Well I decided to clean the egr on my c4 picasso 1.6 hdi all went went and cleaned, or so it seemed. Put everything back, including fuel filter which has not been long changed. 

Anyway car was running okay, bit tricky to start at first but was okay for a day. 

Went to fill up with fuel and shortly after wouldn't start again.

Anyway it started and got me home, then wouldn't start again. 

The fuel filter doesn't appear to have much fuel in it. The priming bulb won't go hard now as I was told to try priming it again. Maybe I've messed something up putting it back in, I've taken the top fuel pipe off and was told to put my finger over over it until the fuel came out......it didn't but there was a gurgling noise.

To top it off I've decided to part ex it, after all that messing around, I know. 

I don't want to spend anything on it now, should I try filling the filter with fuel?? Part ex offer isn't great as it is but I've found a lovely replacement at a great price.

Maybe it's full of air, I'm not sure I've done a few egr valves but not really come across an issue like this. 

Pain in the backside, any suggestion help or tips would be much appreciated ....massively.


Just to add to this I've just been out and undone the air valve and some air came out. After using the priming bulb again it's pumping more air into the fikter but no fuel.

Help please it's driving me nuts

Sounds like the primer is goosed as there is air getting in via the primer, try removing it & checking the diaphragm.

I'll take it off today and search for holes etc. Hopefully that's it

All sorted, it was an airlock. Used a vacuum hose and it's running again. Cheers for the advice
