Coil Negative getting power and not starting - Slant six

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"


OK at least you knock them off my mind and list:thumblef:
