is acting up. when I try to go start my truck up it would not start. All I hear is clickkng noise from the battery and then when I take out the key the truck red security light would flash, the overhead light ans everything else would pulsate and the alarm would go off. I read a few post online and it said that it could be the battery so I replaced the battery and the same thing happens. Im stumped as to why it doez this please help.
