No injector pulse on one injector..need to find cause

Hello,

I have a '98 ZX2. Recently, my car started misfiring. I'm not sure of the cylinder number, but it's the one closest to the driver's side. Long story short, I found that the fuel injector is not firing, if that is the correct term. I used some trick I learned on youtube which involves using a screwdriver to listen for the fuel injector clicking. Anyway, I made a noid light out of an LED and a couple of resistors and found out that there is no injector pulse. I know the noid light works because I tested it on the other cylinders and it flashes. Anyway, I'm not sure where to go from here. I've read elsewhere it could be the PCM but if that were the case it would probably affect every cylinder and if it was a crankshaft position sensor the car wouldn't start.

Thanks for any help.
