Next time please search more.

Check your ignitor chip, make sure it's plugged in and wires are clean and pins have good connection. Also double check your ignitors as well.

It just sounds like drivers from the computer arent quite reaching your coilpacks to fire

What ecu codes you getting? If voltage drops below 10.5 amps during cranking it will not fire.
