I drive a 2000 toyota corolla that has had a dead cylinder for the past few months now and hasn't been firing on a cylinder because of a fuel injector (I could unplug it while running and it wouldn't make a difference) so today I finally decided to change it but when I start the car it's having the exact same issue. What's wrong with it?

How do you know the cylinder was "dead" due to a bad fuel injector? Did you test compression? Have you checked that the fuel injector on that cylinder is actually firing?
You may well have done some damage by driving the car for months that way.
I don't have a compression tester unfortunately otherwise I would have. But no I suppose I didn't check if it was firing either when I did it. Maybe now I gotta [expletive deleted] with wiring or connectors?

could be many things. faulty wiring/connectors. No signal. No ground. Bad PCM.

Chuck raises another point. Unplugging the injector doesn't necessarily point to a bad injector. If there were no spark (for example) the result would be the same.

Please watch your language, this is a family friendly forum.
You can probably borrow a compression gauge from a parts store like AutoZone. There's no sense doing anything else with fuel or spark if that cylinder has bad compression. You should also be able to use a noid light to check for the injector being triggered.
