CRANK POSITION SENSOR?

manual transmission crank position sensor tip worn / rubbing. p0351,p0352,p0500,p0320 codes . 140,000 miles. first problem was it would not start but i could hear the fuel pump run and the engine cranked over. i checked for spark and all four plugs had no spark. p0351,p0352,p0500, and p0320 codes displayed. i have 12 volts at coil. i decided to remove and inspect crank sensor on the transmission side of the engine ( on engine below thermostat housing bolted to engine block) once i removed it i noticed the tip of the sensor was broken, yes, broken. so i knew i found the problem. i put a new crank sensor in and the car started but ran for 1 hour idling as if a cylinder was not firing. then it would not start ever again. i removed my brand new replacement sensor to find the tip was rubbed off enough to see the inside metal. i think it could be a possible warped flywheel but i am having trouble finding diagrams of the excitation part of how the crank position sensor works. i believe the flywheel has holes that excite the sensor. the tribute does move and clutch works for the hour i had it running, so the manual trans does work as well as the clutch
