Depending on your alarm which it sounds like a viper model maybe? on my 02 you have to incorporate a factory alarm bypass module in order to be able to start the truck, they run about 100.00 bucks and have to be profssionally installed. The truck wont start because the computer isnt recieving the proper starting sequence due to the factory alarm

this function is preformed through the Body control module, this can be tested for faults by the dealer only.
