if the engine cranks the alarm isn't doing it. if the alarm has gone off everything just goes blank when you turn the key the starter doesn't get anything. the problem could be a bad pickup coil in the distributor if you pull engine codes it should tell you. also another way to tell if it's ignition related is to crank it for a while and then with a flashlight look down the tailpipe if there is a white misty gas in there it's getting gas but no spark.
ps. don't test if it's gas like i did. a match to the tailpipe makes a big bang lol!
also...if it's a pickup coil make sure you get a junkyard distributor anywhere else is like 300 bucks and NOBODY sells the pickup coils by themselves.
