jus fitted a replacement fuel pump after breakin the old one thru 100% veggie oil ...lesson learned. The car is a peugeot 306 d turbo
new pump is on and the car is running, but the engine will idle ok with the pump in fully advanced position, how ever one slight throtle movement causes the engine to revup to 2000 rmp before settling.
retarding the pump only causes the same problem but evan worse.
the car did run fine before but i did notice when i was locking cam fly wheel and pump that the pumps pullu wheel was slightly out by about a notch.
does any1 think this would be the cause,and the pump needs to be more advanced??

Would be best to ensure it is properly set (as in the pins / bolts are in the correct place) to start with.
If it was me, I'd ensure the pump sprocket was in the correct place (as in the pins fit) and then start with the pump about mid-point / halfway along its 'adjustment'
If its out a complete tooth, you are going to struggle to get it right as I doubt you would get enough movement to actually bring it correct.

I agree.
Start off with it correctly statically timed. Lucas pumps are very critical in this respect.
Basically, If you ensure the pump has gone back onto the cradle same as it came off then it won't be far out. You can see where it was originally by looking at where the fixing nut washers made an impression on the mounting flange.
Basically, you should be able to swing the pump on it's flange slots between extremes where the engine is plainly too far retarded and obviously far too advanced. An over advanced engine will sound knocky and tinkly whereas retarded it'll run softly and smokily.
A long-shot maybe but the pump cradles are designed for both Bosch and Lucas pumps but there is an essential difference in that each pump type has it's own set of stud holes. Running a Lucas on the Bosch position will put the timing miles out.
Has this new pump a good provenance? Do you know it's a good 'un? You say the car ran fine previously but what about the pump? Lucas pumps when subject to storage and/or have historically run on dogey fuel are known to gum up their fuel metering valves; a sticky metering valve could well give the symptoms you have as can air leaks and borderline fuel starvation. Luckily a gummed metering valve is not hard to put right although it is a lid off job.
