[QUOTE="SVTdreamin04, post: 15897013, member: 175069"] Mechanical failure for the most part wouldn't affect resistance. A change in resistance would be related to an electrical failure. Your injector could also be clogged with something. Keep your focus on the key element here. You pulled all of your plugs and 7 out of the 8 looked the same. So, troubleshooting 101 would lead me done the path of focusing on that cylinder itself. You need to eliminate everything that makes that dead cylinder work. 1. Make 100% certain that injector is working. You need to know for sure it is. Right now we are assuming it is. I myself would not think that until I seen it spray for myself. 2. We need to know that coil is firing off. Have you pulled the plug on the dead cylinder to see if it was wet? If your injector is not firing, the plug shod be dry. If it is and you aren't getting spark, the plug should be wet. Eliminate these things and then we can narrow it down even more. Process of elimination. You have eliminated it being a bad coil and a bad spark plug, so eliiminatr the rest of the things mentioned. Sent from my iPhone using Tapatalk [/QUOTE]
