When You said you remove the spark plug and check for spark, I assumed there is a spark and you replace the coil and did not make any difference.

If my understanding is correct, check if there is a the power supply of the coil is complete 12volts, if not, most likely there is some issue on your wiring.

But if my understanding is wrong, and all the spark plugs are firing, but you are getting check engine code of multiple missfire on the cylinder, you probably want to check if the injector is functioning correctly.
