There's a bad connection somewhere. Check the connections on the starter as that's where GM ties in with the wires feeding the rest of the truck. Don't overlook the cable connections on your new battery. Also check the small black wire from the battery negative cable where it is bolted to the inner fender or body. If you don't find the problem, have a test light or digital voltmeter handy when you holler back.
