Hi all I just bought a 1998 chevy blazer LS that had sat for over a year. It ran great for about a week and then one morning wouldn't start. 2 hours later it started right up. The next day it wouldnt start again. I tried again yesterday and it started everytime I tried to start. I did notice a leak in a vacuum hose and wondering if That could be my problem. Sorry for the lack of info I really don't know anything about cars but I am trying to learn..
