Okay the stock coil pack only has 3 coils . It is a waste spark system so when 1 is firing for its power stroke 4 is also firing on its exsaust stroke . So if you have spark on 1/2 your coil pack you should have it on the other side if not your coil pack is toast .
yes, I understand this and why I am posting with a question since I don't understand what I'm seeing with a lack of spark on these other cylinders.
Anyway, the problem I am really chasing is the car will start and then die after 2 seconds. Coil pack has been changed with a known good one, new ignition module, MAF conversion to LT1 style. None of which have made any improvement. (fuel pressure is verified as good at the time it dies).
