Truck won't start



My dodge truck won’t start. I replaced the fuel filter and that cured it for a week then it would’t start again.Took it to a mech. and they scaned it with there computer and diagnosed it as a lift pump issue as the pressure was a bit low. Replaced the pump and that worked for 4 days, now it won’t start again. any suggestions?
