Car Alarms: Autopage XT-72 LCD, remote start, brake switch

Question
For some reason, when I try to remote start my truck, or lock/unlock the doors, nothing happens.  My keychain display shows as if everything is working, and my trucks lights/parking lights go on and off as normal.  I hear a 'click', but nothing else happens, no starting or locking/unlocking.  Any help is greatly appreciated.'

Answer
Really depends on allot of things in place.
Does the system need an bypass kit for the ignition?
Does the remote start need a tach sense?
Are all the wires done including the brake switch and the hood pin?

There are many things that could be happening here.
