Hi Dave,
 
One of the first things I would do it use the two simulation modes of the EC2 to verify (or not) that all connectivity to the injectors and ignition is there.

We dont have that upgrade. Yet.

  It sounds like you spark is probably OK.  But, without the engine running, turn on EC2 power (CPU and injectors)   (but* NOT* the fuel pumps) put the EC2 in mode 1 (with fuel pumps* OFF)* and push the store button.  The injectors should click like crazy simulating firing at 3000 rpm and you should easily hear them without the engine running.  They will continue clicking until you remove power or move the mode  selector wheel to a different mode.
 
 If you do not hear the clicking then you can start trouble shooting the electrical  (you can use mode 8 the same way for the ignition - push the store button and get continuos spark plug firing).
 
Controller B should work fine for starting purposes.  The temp sensor won't make that much difference in the temps we have now.

 
Also *IF* you set the *CS* at *TDC* then that is *incorrect *and would have the ignition timing way off.  To set the static time, the E shaft pulley should be rotated until it reads 35Degree Before Top Dead Center (TDC) (details under *Initial Timing Adjustment* in the EC2 instructions (page 4 in my copy))


We will look into this. I do not have the original crank pully on the motor so we will have to do some figuring here.

 
Then the CS distributor body should be unclamped (loosen the bolt) , pulled out slightly and  rotated so that one pole (the one with the red dot if it is present, but it doesn't really matter)  of the two pole stator is pointed right at the metal core of the reluctor coil inside the CS case.   You may have to fiddle a couple of times to get the CS to slip into the right gear tooth.  But get the stator aligned to the metal core of the reluctor coil as close as you can.   Then clamp the CS distributor body down with its bolt.  The EC2 timing is initially set at 26 deg TBD assuming you have set it up the static timing so it is at 35 Deg BTDC.  If you have then when you start  26 deg BTDC is the ignition timing you will have.
 
If I understood you correctly about setting the CS, you actually have about 10 deg After Top Dead Center set which would be way too retarded.  This may not be your problem as you should still get some pops, but it could be a contributor.

Good luck, want to hear that thing is running
