Maybe look for another break some where?

The Coil pack is good, fuel injector is good, the connector is good, and the spark plug is good.

I would try to see if the fuel injector is firing at all. If it is, then I would run a spark test (there is a special tool, its like $12. It plugs onto your spark plug, then your coil pack plugs onto it. Every time your spark plug is suppose to fire it, a light will turn on.)

Here is one on amazon for $7

Maybe you can go to harbor freight and try to buy one?

if both the fuel injector and spark are working, then maybe run a compression test? Thats usually the last test we perform for a misfiring cylinder. Most of the time it ends up being spark.
