Help -Engine will not start
 

I just fixed my ingintion lock, so I had to remove Instrument panel, and unplug Ignition wiring. Now that i put it all togeter, my engine rotates but will not start. On the inst. panel the oil presure doe not rise when you turn ignition to 2nd position, it only rises when engine is strarting to turn. It started couple of times for just a second, but than died again. I had never have any engine/starting problems 'till just right now. Any ideas. Oh I have '84 300D turbo:confused:
