Won't start very easy when it does go's about 10 miles stalls out. Changed fuel filter , got rite of heater sencer in filter . Then lift pump wouldn't work , today it works . Two codes 336,236 on check engine

 

Fuel pressure good? It should only have a "water in fuel" sensor in the filter. We need to see if the lift pump is working if you starve the VP44 injection pump of fuel it will fail then you will have to spend a lot to fix your truck.
