    lb7 dual fueler tensioner issue.

    Well, it may be the tensioner, or the belt needs to be a little longer, right? I would ask PPE what they think. They have had much experience with these things.

    LML Rebuild - Crank No Start

    Cam and Crank sensors look alike so if you didn't keep them organized, it would be easy to swap either the sensors or their connectors and not know it until you attempt starting.

    It could be lots of things. Make sure your batteries are fully charged for starters. Remove anything plugged into your diagnostic port and anything that is an aftermarket electronics, like radio, remote start, etc. Sure would be nice if you could stop by a parts store and get your code read...

    Can't you buy the extended warranty at any Chevy dealer? And don't different dealers have different prices for the same coverage? May be able to purchase the warranty for some time after purchase. Might want to check into that.
