got my 280i running

[mikek]

after a little playing around i got my 85 280i running. but it seems that the fuel pump only works if i run a jump line from the batt. what can be the problem that the factory power line to the fuel pump isnt gettting power? also my car is idling around 1500-1800. it has the bosch fuel injection system. what can i do to bring the idle down? i have the screw all the way in that the manual says controls the idle speed that is located below the intake for the throttle body. any ideas are always a great help.
thanks

Check the condition of the metering pin on the other end of the flow meter arm it should move smoothly and drop into place with a definite 'click' if this sticks it can end up running the system rich. Also check all the hoses after the flowmeter / metering head as any air pulle din after this point can also screw things up. Finally a really simple check but is the throttle cable caught up on anything or too tight?
