Default nissan help, cylinder not firing, Please help!!!

Well not too long ago my 94 nissan altima started to run terribly. I tested all of the electrical stuff and didn't find a problem. The cylinder is not firing at all. What else could it be?

i would try simple things first...try swapping that cylinder and another's wires and see if the problem moves to a different cylinder. Check your cap and rotor...Does this have the FWD ka24? If so the cap and rotor are 20 for the pair. Try that first.

Do a compression check, it sounds like you may have a bent or burnt valve in that cylinder if you have good spark and fuel.

Have you checked the injector on that cylinder to make it's working correctly?

That is what i am leaning towards. That or a vacuum leak somewhere on the intake manifold by the injector. What is the best way to test the injector?

I would just switch it to a different cylinder and see if the problem follows.
