I have a 1995 Chevy Suburban with an aftermarket Avital alarm installed. Lately I have had issues starting the truck. Mechanically it is in perfect shape. Have over a quarter tank of gas, and the thing turns over no problem. But there is no start. SOunds like the alarm has disabled the ignition system. How do I reset or disable the alarm? Not sure what model, all I know is the remote says AVITAL
