Need some knowledgeable help. On my stroker build i believe i have a cracked intake. I checked the heat on each header pipe to find which cylinder was dead. The number 8 cylinder was not firing. Changed coil pack and checked spark good to go. Still cold pipe. So was thinking fuel injector. Checked signal with my noid test light and it was good so i changed the injector. still cold. Plugs are still brand new no brown or white. When i pull the intake that cylinder is BONE dry but the others are full of fuel. Is it possible that the intake is cracked and the vacuum is pulling the fuel into the throttle body and dispersing it through the other 7 intake ports?
