cranks but no spark at coil

4spdragtop said
Ok cool cuz its a 7 blade but only 5 are used as there are only 5 female connectors that hook to it. So theoretically only 1 more as the cuda has 4 connections (I think)
So the coil +ve while cranking test. ...is that coil +ve to.ground with meter or coil +ve to a starter relay connection?
Sorry, not quite sure which way you mean.
Thanks again Del, electrical "babysitting" over the net has gotta be frustrating lol.
I appreciate all the help/input.

You are trying to see if the coil is getting voltage. Just hook from coil+ to ground and see if you have voltage in "crank". Would not hurt to double check after key returns to "run" see that you have a lower voltage there, perhaps 7--10V or so.

Do you have a dual ballast? Does it appear the ECU is original? Could be trouble there. The "tap test" earlier should eliminate that
