Thread: RPM IS NOT WORKING

I'M PUTTING MY CAR BACK TO STOCK SO THAT I COULD HAVE MY CAR REFEREE. I GOT EVERYTHING PLUG BACK IN, I START UP MY CAR AND REVERF MY ENGINE AND THE RPM WAS WORKING. THEN I SHUT THE CAR OFF AND RESTART MY ENGINE, MY RPM IS SITTING AT ZERO. I REVEF THE ENGINE AND MY RPM IS STILL SITTING AT ZERO, IT'S NOT MOVING AT ALL. WHAT DO YOU GUYS THINK IS WRONG WITH MY CAR? PLEASE HELP.... THANKS... TU
