I used a timing light on the cables, but not sure how to tell other than 
this method whether it is actually firing the plugs.  Now I think about it, 
if there is ground, i.e. spark at the tip, the current should flow and 
trigger the light.  See, I have had to question my tests, as it should be 
running after all these hours of work.

Not sure where it is coming from, but is in the area of the engine.  Can 
check the injectors if needed.

Can you hear the popping/spitting?

I was trying to get it to pop or spit for you all.  Also getting a bit peeved
at it all, as tired of quitting, especially in a borrowed garage that it was 
to leave a couple weeks ago.  I did try full down, but does not seem to help.


Thank you so very much!
