Default Coil pack going bad?

Usually the motor fires right away, past two days it now takes a second to two seconds for it to fire?

I'll pull codes tomorrow but was just curious if it might be a coil.

thanks

I agree...fuel pressure and add checking the battery voltage when the ignition is off.

Turn the ignition to the on position, let the pump prime, and check for bleed down.

VERY highly unlikely that a coil is going bad.

If it were, you would see a MISFIRE rather than a long start.

Ive owned two C5's and a C6 and worked on 100+ C5's and have never seen one coil pack or coil go bad. Thats not to say that they dont or cant go bad but, its not a common problem for C5 coil packs to fail.
