Here's a first step: Put key in ignition, turn on but do not start car. When dash lights up, the alarm light will flash if it has been triggered. If this alarm light is flashing, you have set off the alarm. Here's how to reset it: Leave key on, and let the thing flash for five minutes or so. Finally it will stop flashing on its own. Now start the car. If it runs ok. Kill it and turn key back on to check if light has stopped its flashing. This may be way off, but that is the reset procedure for alarms on those blazers. Man I've seen a bunch of them in my shop this year!!!
