I have a 2000 GMC Jimmy 4.3 l vortex and when its cold it runs great but when it gets hot it spits and sputers, and don't want to take gas then it acts like its flooded. I change the fuel filter and the core I also checked the fuel pump when it was running and when it was off. What is wrong with it? Please help.
