CS 2009 FM and 1995 Legend

Please Help !!!!!!!!!

I bought 2 units of remote car starter (cs 2006 FM Model) and I successfully install the first one on a 1995 Chrysler Concorde(without Factory alarm system), but I got the problem when I installed the second one on 1995 Acura Legend (with Factory Alarm system).

There are 2 problems:

1- The remote alerts with an audible signals and showing "doors" on the LCD. (The door wirings had been checked 3 times already and they were correctly hooked up)

2- When I use the button II to start the engine, the unit power every thing up just for a second or two, then shut the system off . It doesn't even trigger the starter to kick in.

Despite I used the wire that disables the security, problems remained the same.

Any ideas or suggestions will be really appriciated.
