can you be a little more specific??
If you mean that while the car is cranking with the key that the tach stays at 0rpm, that is mnormal functionality, but if the tach goes to 0rpm while driving or while the car has already started, that indicates a problem with the engine speed circuit. When the car sees a possible error with the engine speed circuit the computer defaults the tachometer to read 0rpm
