No pulse on Injector 2

Hello. This the second post i have written about this but i really can't believe no one has any information on the topic. It most likely never caught the eye of the right person. But anyway, I have a 2000 jeep cherokee Six cylinder 4.0. My problem is I have no pulse on the wire going to injector number 2. It is causing a misfire in cylinder 2 and comes up on the scanner as misfire on cylinder 2/injector2 misfire i forget the codes though. Now i have replaced spark plugs, checked coils for the spark plugs,junk yard fuel rail and like new injectors. Now the two wires that are coming out of the injector which are green/orange stripe which is ground and the other which is tan goes all the way back to the pcm. The ground wire is good. Now for the tan i cannot find any damage to it as it runs back to the pcm. I want to replace my pcm but i want to hear people opinions on the subject first. PLEASE HELP ME Its been off the road for a week and i cant stand it. Thanks
