2005 Mazda Tribute remote start problems

Clifford RS1.1 remote start unit.  DEI 556U transponder module.  Wired with inverting relay via Directeds 1079 direcfax.

The car will start up fine, then die approximately 6 seconds later.  Then it will do it over and over again until the alarm cycles out of retrys (3).  If you remote start the car within a short period (within an hour of leaving it) it will generally remote start and function like it should.  If you leave it longer (typically overnight) it will perform the above actions.

It has been rewired without the 1079 and just the (+) keysense wire from the 556U feeding the car with no luck

Tried to change the tach sense to voltage sense with no luck.

If you take off the transponder antennae or remove the key from the transponder it will not crank at all, so I don't believe that is the problem.  It's almost like it's a tach signal issue since it starts fine then shuts down, but I am out of ideas!!!!

Help please!

Here is a very simple test you can do anytime you are tryine to figure out if it's a transponder issue or a tach issue...

Start the vehicle with the key, then do a take-over with the remote starter and remove the key from the ignition.  If the car stays running, your tach signal is not likely the problem.

As the previous posts says, if you remote start the vehicle and the key symbol in the dash starts flashing, you have a bypass problem.  As a rule of thumb, you should always test your remote starter installation with the vehicle's own key in the ignition before doing your bypass.  This eliminates any questions about wiring problems after you do the bypass.
