If you are getting sparks to cylinder # 4 and none to # 1, the coil pack is faulty.

Retrieve the trouble codes and let me know what it is.

Are you getting sparks to cylinder # 4? They both share the same coil right?
Did you pull the ignition coil out, attach a spark plug to it and crank and check for sparks? No ignition sparks and cylinder not firing are 2 different things.

I am trying to confirm if it is missing sparks at the plugs that is causing the problem or the cyinder is misfiring due to other reasons and I am not sure if you are doing the testings correctly.

Let us go over this again one more time.
Disconnect both ignition coil packs.
Remove the # 1 coil pack.
Attach a spark plug to it.
Reconnect the wireharness.
Ground the spark plug by holding it to engine.
Get someone to crank the engine.
Do you have sparks when it is cranking?

Ok, problem is not due to no spark.

Check the fuel injectors. Test the resistance and manually test if it clicks when battery voltage is applied to one terminal while the other is grounded. Use clicking motion to test.
Use a noid light across the injector terminals to test if it pulses when the engine is being cranked.

You would need to test if the circuit to PCM is broken. Do you have battery voltage at one terminal?
If yes, use a jumper wire and connect the one that does not have battery voltage to # 4 fuel injector wire that does not have battery voltage and try starting.
