crime stopper alarm

I have been having some probs. changed the battery and starter. I have power to the car nothing comes from the starter. no clicking...nothing. Checked with multi meter and have 0 from the ignition switch. My crime stopper alarm is also not working properly. I.E. alarm can be set and I can open the door without alarm going off. When I turn the key to start I can hear a click by where the alarm is in the dash behing the E-brake. Same click when I lock the doors. Any ideas?
Could the problem be the alarm and the kill switch?

if the alarm system is not working properlly, it may be disabling the starting system preventing the car from starting. try having the alarm system fixed, or removed all together
