So I have a 2001 dodge ram 2500 5.9 gas 2wd. The problem I’m having is the truck will start and run good sometimes and sometimes it just dies as soon as you start it, it also always throw a p1296 and a p0505. I have changed fuel pump, pick up coil, cap and rotor, spark plugs and wires, and all of the sensors on the throttle body (map, iac,throttle position sensor) and also have replaced evap canister. I need help
