#5 cyl. Not firing. Pull injector wire, no rpm change.
Compression good, spark & spark plug good, plug wire & cap good.
Replaced #5 injector, checked each injector wire(both sides for voltage & Pulse) all seems normal yet cylinder dosen't fire?
Thanks Ahead

If you would pull the number 5 wire and ohm it and let me know what the ohms are the length of the wire. Also what brand of plugs are you using? Have you replaced the plug to see if you have a bad one? Get back to me thanks.

Great glad to hear it. It runs like it should again. So the plug gap didn't understand what you said about that but as long as you gapped the plugs to the specs on the sticker under the hood then no worries. Thanks for you support and if you have any other questions please just ask.
