Or to 'xplain a little more, if the test lamp on the coil neg is bright, we have a wiring or ECU problem,
If the test light is dim, "pretty dim," might be "normal."
Make sure you have power to the coil when cranking. Try adding a clip lead from a battery source to coil+ during testing.
2--Condenser on coil+ only is for radio noise supression, not needed
3-Ground strap probably not the cause of this, but you DO need battery grounded to block and body
4--With no spark, plug wiring is irrelevant for now
5--Irrelevant for now
6--If engine cranks not a problem, and certainly not the cause of "no spark"
