Ka24de cylinder #2 not working?!!!? Help!

[svtcobraxx]

i thought my headers cracked so i replaced them. Then found out i was off timing so i moved the dizzy and it fixed it but i found out that i was only on 3 cylinders. i replaced the spark plugs and tried 2 different injectors(not sure if broken or not) and im deff getting spark cuz i put the spark plug wire against metal and i hear it and i put a volt meter on the injectors and they were around 12v. im really hoping its not my piston rings or valve seals...i dont know what to do, i really hope its just a simple problem :/ anything would help thanks! oh yeah and since i got new headers they all usually turn bronze and they did except for the second one...

Compression test it.

ive narrowed it down that its deff an electrical issue. i moved the clip that goes into injector 2 into injector 3 and then cylinder 3 wasnt working and cylinder2 was working again. i checked for continuity and it was good and i had like 13 volts so i was deff getting power. i dont know what else it could be???? please someone help lol

Injectors always have a shared 12v to them and are grounded individually in order to fire.

Here's what to do:

Do a compression test and/or leakdown test.
Swap injectors with another cylinder. See if the problem still only persists in cylinder 2.
Ensure continuity between #2 injector signal wire on ECU to harness plug at injector.

Profit.

ive swapped the injectors and the problem was still at injector 2 so its not the injectors its the wiring. yesterday i completely took apart the wire harness and then i figured out that it was the ground because every time i started moving the harness at some points the injector started working again and cylinder 2 was working!!! but only for a lil it kept cutting off. i couldnt find where the wires were fucked up though???? i still dont know what to do lol

bumppppppp

lol, yet another person that just swaps wires. Its a good thing it actually fired at that time. Its always better to move an injector then it is to move the wires.
