causes for a cylinder not firing? (sr20det)

[2forty]

i am stuck. Cylinder #1 is not firing. have had my swap running for a few days now. it has never fired. my stainless manifold is still stainless off the first runner, the other three are bronze. it is not producing any kind of combustion or heat. i have checked my injectors, and replaced it. my coil pack works in another sr20, and i tested it to see if it would arc to a ground and it did. so the injector and coilpack are getting power. what else could cause it not to fire? timing? ignitor chip? wiring? im gonna do a compression test tomorrow. has anyone had a similar experience with an easy fix that im not aware of?

check your wiring also, the way i checked, i unplugged the plug for injector #1, switched it with #2 to see if it'll work on #2 then yeah, if it doesn't work then voila, it could be your wiring, hope that helps
