[i<3 my scion]

Hey guys i just recently installed my viper alarm 791 xv. The reason why i installed my remote start was because of the security and also to warm up my car in teh morning cuz im lazy ahha. Everytime i turn on the remote start it attempts to turn on but shuts off. After the second a attempt it turn on. it gets kinda embarassing when u try to turn it off and it wont start. i installed under a licensed dealer. Is it something i did wrong!!!?????
SOMEONE please help.
