[Gmecm] Bench testing a GM waste-spark DIS ignition

[Occy]

VW datsun nissan also of vintage, I once working at a datsun dealer had an 
efi problem, my number one rule was to check the brain as it was called in 
those days, and it had a vw brain in the datsun and as normal that wasn't 
the problem, this case was a fuel filter... they must all be the same.
