Presuming the same car -

406 , i picked up a 2.1 diesel that had been stood for two years with no starting well after some cranking and a lend of a battery it started now for the questions
what should the rpm be sitting at ?

Start with the leakof pipes and work towards the fuel filter then the tank from there.
First though check the fuel filter housing seal as if it has recently been replaced there could be air ingress there.

A favourite spot for leaks on a 2.1 is the rubber primer bulb, they are generally available from most decent motor factors, I believe GSF sell them.

Another favourite is the rubber blanking cap on No.1 injector at the end of the leakoff pipe daisy-chain. It often splits.

Have you replaced the glowplugs? These engines need good ones. Does it start better if two glowplug cycles are given before attempting a start?

A good check of the glowplugs is to observe the exhaust when attempting a cold start. If the exhaust issues white smoke during cranking this indicates unburned fuel as a result of ineffective glowplugs. Conversely, if nothing is coming from the exhaust then the problem is air ingress.

Given that you can see air bubbles it's unlikely to be glowplugs but its always worth a check...

hi guys thanks for reply havent changed anything yet except fuel filter could this be the problem as when i took the old one out you could see the paper element around the out side however the one i put in you could not it had a hole at the bottom to witch i thought that it would draw from there and filter as it pulls it up as for the leak off i have some pipe somewhere so will change at moment i am trying to fix with no money as i am waiting till after x-mas but i will look at what has been said
