Default 2.2 DIESEL fine when started the erratic after revving

just bought my self a 2002 Pt cruiser 2.2 crd. im in the uk.
now the problem is ,
when i start the car the tickover is smooth, but as soon as i rev it it acts as though it is misfiring. and tickover is as rough as hell.
if i turn the engine off then turn the key to start it , i have to wait about 10 - 15 seconds before i can get it to even turn over and start again, (no light dim when i turn the key, it just wont turn the starter motor .)
whilst running if i turn on the heater / aircon etc the revs drop quite a bit..
i have just put in a new diesel filter as the old one was leaking out around the seal.

the engine management light is not on, but do work.

it seems like, when i rev it the fuel pressure drops, and when the engine is off and i turn the key to the run position for 10 to 15 seconds the fuel pump comes on and the pressure rises the fuel system,
start the car and its smooth again until i give it sum revs, at one point it would not rev above 3000rpm , other times it will rev past 3000rpm, the roughness starts around 1200 to 1500rpm ,

would get a video but being a new member i dont know if i can link to it from youtube,
