      I have a cracked head gasket and I've been told i must pull my motor to get to the timing chain and replace head gasket ect. Going to try K&W gasket sealant. Instructs me to remove plug from the wet cylinder and disable fuel flow to that cylinder. How do I stop fuel flow to one cylinder? Thanks for your answers, you guys have helped me alot in the past!!

      yeah thats what i was going to do but a buddy said that disconnecting the wiring wouldnt stop the flow of fuel. He says that only regulates lean/rich mix.

      Pulling the plug to the injector generally doesn't allow it to open; otherwise your engine would flood when you powered the ignition. Do have a fire extinguisher handy for whatever you are attempting here.

      That was why I said to pull the coil connector too.

      removing both is definitely best here. In the end, if your head gasket is really bad, its gonna need replacing.
