Not starting, won't turn over

As always, thank you for your help! 
Bentley contradicts itself, 27.20 shows terminal 50 as the one left, on my  
solenoid that is labeled 15a. 27.22 shows terminal 50 as being the one on the  
right, that is labeled 50 on my solenoid. Which do you connect to and will I 
fry  anything if I'm connected to the wrong one?.... which ever that may be.  I 
been connected  connected to the left one in the past.

I don't  believe anything in the ECU will stop the starter from turning.  It 
will  stop the ignition from firing or the fuel pump from pumping, but not the 
 starter from engaging.   Other than a starter malfunction, there's  an 
outside possibility of bad ground to the engine and starter.  The  starter grounds 
through its mounting, but that's to the engine.  You  could have a bad ground 
to the engine that would give you a bad ground to the  starter.   I think you 
need a starter  overhaul.

Battery shows  12.5-6 volts

I followed Bentley, with key to start I get 4 volts  [should be 8 or greater] 
at terminal 50 [small wire] on the solenoid. I  get 12.6 volts to terminal 30 
[big wires] on the solenoid. I disconnected  the ignition switch connector 
and have 12.6 volts coming to it via  terminal 30. I have .03 ohms resistance 
from the switch to the solenoid  along the thin wire going to terminal, 
as far as I can tell, my  wire paths are in good shape, getting power to the 
solenoid and switch and  have a solid path along the thin, often maligned, 
wire going to the  solenoid. Battery is good, grounds are good.

Bentley said replace the  ignition switch. I did, no change, still 4 volts at 
terminal 50. The metal  tang in the ignition housing that mates with the 
ignition switch is  solid.

I looked at wiring diagrams in Bentley, but, I'm not real good  at reading 

I pulled codes and get open circuits on all  injectors and an open circuit on 
the waste gate frequency valve. I checked  the waste gate frequency valve and 
it checks ok. I'm not sure how to  approach the injectors.....and I could see 
how these would hurt running  conditions, not starting conditions.

So, any ideas?

Thank you!  Bob 91 200q20v
