Also you never said that if the vehicle did start up at one of the "middle points" was there a bang or sudden acceleration (hydrostatic lock on the injectors).

No it does not. If it does start in the middle points (sometimes after I've cranked it three or four 5-10 second cranks separated by 10-20 seconds waiting) it sounds like normal.

A quick test would be to have a friend attempt to start the car while you placed your hand over the air intake and removed it after a few revolutions or until the car started. This test would indicate a black box interface with both the injectors and the spark unit, as the pumping motion of the piston movement would suck in more fuel if your hand is acting like an old fashioned throttle plate.

I don't understand what this means. I'm a car lightweight. I haven't worked on a car since my 1967 Mustang and it was much simpler, and had a carburetor.
