Replace the airbag lamp in the cluster, and get the LFC ( Light Flash Code ) to figure out what the problem is with the SRS. The 5x5 beeping is an indication that there is a SRS problem waiting and the airbag light cannot give the LFC. Page 105 in the owners manual.
Once you replace the airbag light, you will get a LFC that is a 2 digit number presented by the flashes. Example is a LFC of 42, the airbag light would flash 4 times, pause flash 2 times pause and repeat.
Once you have the LFC, either start a new problem, or add a comment to this problem with the number for further diagnoses.
Turn the key to the start position, but dont start. Wait for lights to stop blinking and push the brake pedal down a few times, light should flash again, turn ignition to off and remove key, exit car and lock doors, use key to open door and then try to start it. Good luck.
sometimes turning the ignition on 3 times quickly without starting will reset the computer. If the van has power locks and keyless entry then try using only the keyless entry. Sometimes your car wont have a alarm but an anti theft device which will not allow it to start if it goes off or something triggers it.
Sounds like you have an aftermarket alarm with starter disable. By disconnecting the battery the alarm reset and the defualt setting is usually to set the alarm automatically (active arming). You have three options.. A. If you have the key fob that went with the alarm you can disarm the alarm. B. If no key fob is available you can disconnect the battery again, turn the ignition key to the on position and reconnect the battery. This usually doesn't allow the alarm to set and allows the car to start. C. Remove the aftermarket alarm system. This is usually the long term fix i recommend if the fob isn't available. Option B should get you going though.
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!!!
The ignition security on/off is located at the trunk lock. unlock and lock rear gate and the alarm will turn off. My jeep sat in my drive for a month before a jeep tech told me this. It still triggers the security sometimes when I unlock the passenger door with the key and I go straight to the rear gate lock and it shuts off instantly.
