I have a 92 Blazer that I use for plowing. Dont drive it much any other time, so once in a while I will go out and start it up. So I did this about two months ago, no problem fired right up. Today went out and battery was totaly dead. Jumped it to my other truck and Factory Code Alarm started going off and would not shut off. Finally I had to cut the siren wires. Now truck turns on but will not turn over. Parking lights keep blinking, remote for alarm does not work. I disconnected all the wires from the alarm unit and still does same thing. What could be the cause of this sudden no turn turn over condition?

 

Well I replaced the battery in the remote hit the unlock button, got in and it started right up. IS there a way to remove the factory alarm?

 

Check under the dash by the steering column. Look for, I think, a yellow wire. This is your starter wire. From the sounds of it, the alarm was installed with a starter kill relay. Just remove the relay and reconnect the yellow wire together. When removing the relay, make sure that you remove all wires! You don't want to leave a live 12+ volt wire just hanging around under your dash! This should solve your no start problem.
