1992 firebird sometimes just won't start. We changed the starter so it isn't thatl. It isn't the battery. Thinking it maybe the alarm system. Anyone have this problem?

 

my car is doing that too.. sometimes it wont start.. theni can go back and like 10 minutes later.. it will start .. i toook mine in the shop to see wat was wrong wit it..they couldnt figure it out.. i also replaced my started.. it wasnt that...

 

there has been alot of problems with the VATS systems on the cars so equipped, do a search for "VATS", there is a tech article on how to bypass the system. most people with these problems end up finding out that the culprit is the vats. (VATS=Vehicle anti theft system)
