Hello,

 

It gives no tach because vehicle did not crank. What's important to look for is if ignition turning on.

 

please start with a reset and reprogram. 

Reset procedure must be done, options will need to be re-enabled after the reset. unit will need to also reprogrammed to the car and also redcrypted. 

 

  1. Hold down programming button while inserting the power.
  2. Let go of button when the LED is RED
  3. Push and Hold the programming button until all three LED start to alternate rapidly
  4. Module is now reset.
