unit shuts down 4-5 seconds after remote starting

I HAVE A HONDA CIVIC 93 3 DOOR HTB. I INSTALL A FM-2009 REMOTE ALARM W/STARTER.   EVERY THING IS WORKING FINE BUT THE UNIT SHUTS DOWN 4-5 SECONDS AFTER REMOTER STARTING.     I DID CONNECT THE TACH FORM UNIT TO THE TACH WIRE ON THE CAR BLUE AND SET SW TO TACH MODE.  I CHECK THE TACH WIRE VOLTAGE IS ABOUT 7.522.... I ALSO TRY TO WRAP TACH WIRE FROM THE UNIT  TO THE PLUG/COIL WIRE, STILL THE UNIT SHUTS DOWN 4-5 SECONDS. PLEASE HELP.

Is there no tach programming sequence that you have to go through for this unit ? The reason I ask is because the tach signal from a plug or the coil is usually a 1 cylinder signal . If the unit cannot see this you are not going to get the right tach.
