your problem is hard to diagnose in a forum. might be the module that keeps accessory power on after key removal for 30 secs. check your door switch for alarm. if aftermarket alarm, you will need to check most wires you plugged. something is probably doing a short or loose...good luck

 

Some cheap alarm systems have a fuse you can pull located near the "ECU" of the alarm. Most installers place it under the driver side kick panel which is just above the pedals. Try pulling it out if it even has one, then try starting it. If it works for you remember that by pulling the fuse you disable the alarm.
