This is a new build, and #3 cylinder is not firing. I readjusted the lifters on #3 intake and exhaust, I put in a new spark plug on #3, I put a different plug wire on it, I inspected the distributor contacts and all look fine. I removed the plug wire and started it up and re-attached the plug wire while the engine was running and no difference. I put the #3 plug wire close to ground while the engine was running and it's throwing a big ass spark (MSD). All the plugs look good except number 3, I verified the plug is firing but the cylinder is dead. I checked the compression and it's the same as the other cylinders. Could this be due to a bad hydraulic roller lifter?
