The truck would stall after getting gas and would do it after a heavy rain and it being left outside in it. We thought dirty gas/fuel pump going out/water going into fuel pump some way etc. We have replaced the fuel pump, fuel filter(twice), and the inertia switch. It will not start. It will only crank. We took the bed off again and looked at all the hookups to the fuel pump but everything is connected correctly. What else could this be?? It is definitely a fuel issue but we don't know what else to do for it! It also has a miss around the 50-60 mph range. It needs new spark plugs for sure, but that shouldn't be the issue should it??

Thanks for any help!
