I build a test harness with the insulation stripped off at intervals so that I can wrap all 4 plugs at once and ground at one point.
ECU and twice unit, correct voltage thru ignition switch?

If spark is the issue, what would prevent spark from occurring? I have to find my back up DIC but the DIC in place is a brand new 2013 unit. The spark plugs are correct and brand new, just checked the gap before and are all perfect.
Again, how do you check the cps? Thank you.
