A colleague took the end off the PAS pump and cleaned the accumulated carbon out on his Saxo which fixed the PAS for the rest of the time he had it. I think he had to take the pump out to do it (although he couldn't release the hoses, so ended up doing it with the pump hanging under the car), and it involves peeling back the tabs to get the end off IIRC.
The lumpy starting may well be valve clearances closed up, or it could be perished leak off hoses letting air in if it has a Lucas pump (Bosch pump + air = no start!).
