Sos alarm spasms 1996 e150 5.8
 

Please please please someone help me before I load this van with Tanterite and shoot it. I have a 1996 e150 van I got given to me from this lady. She was the only owner. There is 63xxx miles on this hog. I was awaken today by the alarm going off at 10x speed of rate. I unlocked it with key and started it but it kept going off I disconnected the battery and reconnected.. still going off at 10x rate of speed. Please any info will help deeply.
