heres what 224 is.

224 (M) Failure in ignition coil primary circuit - Ignition Systems

so it may not be the actual coil. check the power going to the coil

Checked power to both coils at the connector got 12v , checked the resistance at 1&4 , 2&3 got 13.38 ohms on both packs. Whats next?
Thanks Lou58
