About a month after I purchased my truck I noticed an extended cranking. I took it in to the dealership and the truck didn't make the noise. I took it back in a week later and they said it was the fuel pump. They replaced it, but about a week later it did it again. I took the truck back in and they said they couldn't duplicate the problem. I'm getting the run around and no one is willing on fixing the problem. I don't know what else to do?

truck is hard to start after the truck has sit for 20-30min. after you have driven it. Truck would turn over for 5-8 seconds before it would start. This is a intermittent problem that would happen 2 times a week. took truck to local Chevy dealer to have looked at. that could not get truck to do it so they replaced fuel pump. got truck back and a week later it happen again. took it back and this time they replace throttle body per Chevy tech line. hope its fixed
