Engine turns over fine not getting any fire from coil or feel from injectors. What could cause this problem?

Good morning,
You will need a test light to do some checks.

Check for power to the positive side of the ignition coil. if you have power, then test the negative side as well. if you have power, crank the engine and see if the light flashes. if it does, you have a bad coil. if it does not, you need an ignition module or/and distributor pick up in the distributor.
if you do not have any power to the coil, check all your fuses for power on both sides with the key on. if they are all good, chances are you need an ignition switch.
