Peugeot 205 diesel starting problem - battery ok

[noplanb]

My K reg Peugeot 205 turns over but refuses to start without priming the fuel filter. I changed the drop in fuel filter, primed the fuel line to clear any air, the car started and ran all day without problems until the next morning, when I had to prime the fuel line rubber bulb again before it started.

The next day I had to prime the fuel line again and kept turning the ignition until it eventually started with clouds of white exhaust. Today I could not start it at all. The battery is fine.

Should I try bleeding the injectors - how do I do this? Is air getting in to the system somehow when it is standing overnight? Can anyone help?

Its very common for the rubber primer bulb to crack, replace this with an aftermarket one for around �10

Thank you for your answer, I will check the rubber primer.

Did you re-new the fuel filter+ rubber seal? Poss cause.

Yes, I bought a new filter with rubber seal
