Bought the motor less than a month ago it was running at the time but low compression on 1 cylinder due to bad head gasket. Replaced head gasket installed motor on my boat plugged in all the electronics it will crank has good compression on all 4 now and is getting fuel, but has no spark at any of the coils. Checked all the fuses. Some of the grounds were lightly coroded so I cut them back to clean wire and installed new terminals on them and cleaned the ground post. I dont know where else to look for an issue any help would be appreciated.
