i was racing yesterday and i shut down the car while waiting in line. when i went to start it i have no rpm tach on my gauge, it took 15 sec then i got tach reading and the car started. later during the day i did one pass then i when back to wait in line, let the car idle for 3-4 min. when i tried to start it again nothing. no tach reading. my guest its my distributor sensor its gone. but just to make sure. if i got the ms2 signal unplug and i crack the car, i should see my tach on the dash moving right??

Start with the basics:
Open megatune/tunerstudio and look to see if the MS is reading the engine RPM while cranking on the gauge. If it is not, there is an issue with the tach input circuit. If the RPM shows something like 100-300 RPM during cranking, the input side is fine but there is an issue with the output circuit that triggers the coil. This includes the igniter and coil itself.
