My mechanic got the new motor in. It is from a 1990 760 Turbo. Great compression. He used my intake manifold and electronics only using the head/block from the 760. He has checked all the injectors...put a new MAS and coil on. The car will start after cranking and cranking and won't rev. He put another Fuel Pressure Regulator on and it made no difference.

My last thought...could the overheating have caused a shortcircuit and fried the computer? I can get a computer for it easily at the salvage yard. I checked the numbers and there is one there for it. I went by and went over all of it with him. It's baffling both of us!!!

Any help is appreciated. These boots are may have been made for walking...but not THIS much!
