pug 205 GTI

[TDi90]

my neighbour has a pug diesel 205 GTI and it wont start...
i traced back to the fuel to make sure fuel was coming through, and on top of the tank i took off one of the hoses and blew the fuel through to the filter... it ticked over for about 2 seconds (!) then cut out, and when i tried turning the key again after it tried starting but seemed like fuel starvation... is it the lift pump that has given up the ghost? or am i being dim and missing something? (where is the lift pump on one of those by the way?!)

any help gratefully recieved!!

now is it a GTi or a diesel?
they didnt do a GTdi in the 205

The pump is part of tje sender unit on both the diesel and petrol, sounds to me like the pump is up it ?

D turbo  :oops: :oops:

What happens if you build up pressure in the system using the priming bulb? will it start then? will it keep running if you keep pumping the bulb?

[TDi90]

where is the bulb? or thing i have to pump? i cant find it  :roll: looked everywhere!

If its a diesel has it been parked on a slope facing back slightly downhill?- A problem a mate had (apparently common according to a pug mechanic) is getting a small airleak somewhere in the fuel lines and the non-return valve on the pump not operating so all the fuel drains back to the pump- It then needs to be re-primed to start.

Hope thats some help.

On most pugs its on the left hand side near the strut top somewhere, its a black rubber bulb thar is located in the fuel line. give it a good squeeze, you will feel if there is fuel in it, keep pumping till you feel the pressure build up.

Is the fuel filter on the os inner wing?

[Tommo]

Fuel filter should be on the rightish side of the engine, its a big black plastic thing that the fuel line goes to (also it has an air bleed screw which must be shut) has 4 bolts on the to that hold the lid on and the filter is in there.

This is a 306 1.9TD but its relatively similar...

[TDi90]

thanks tommo! looks similar not identical though, ill get a pic tomorrow to show you all!
thanks for your help everyone! much appreciated  [-o<

205 1860cc is different to 306/405 onwards.

[TDi90]

that looks a bit more like it  :P

I had the 205 engine in my c15 van but i was sure it had the fuel prime bulb and the filter in the same place as the 1.9's. Cant spot either on that pic.  :(

IIRC the 205 D-turbo is a bit inbetween, it has no intercooler either.

92 on (ish) had the bulb and top hat style fuel filter.

[TDi90]

ok here we go pics!



on this pic, i have undone the right hand side bolt going into the top of the filter and turned the car over, no fuel is coming through  :? i think this is where the problem lies to i traced it back to the back of the car, where it goes int the fuel tank and when i put an airline through from the other end it comes gushing through! so does this mean the lift pump is at fault?

here are some more pics!








thanks in advance!!

Im not sure what happens there really, is there a way to prime the system? that black thing on the top of the filter isnt a button is it?

They dont have a mechanical lift pump IIRC nor an electric pump in the tank, must just rely on the injector pump to draw it through?

[karlo]

Have you tried bleeding the system at the injectors?

[TDi90]

no - how do i do that? just take the injectors out and see if they spray?
Rob

[Tommo]

no i wouldnt advise that! the spray from injectors can easily penetrate the skin and dosent do you any favors. just crack the fittings off that attach the pipes to the injectors, undo them about 3/4 a turn and turn it over until diesel starts flowing out from the joint. Tighten them back up again and give it a whirl.
