2007 Nissan Navara Codes P0628 P1272

Question

Vehicle will not start up sometimes as though its not getting any fuel and after turning the ignition off for a few seconds it will then start but at times you have to press the throttle. Taken it to the garage and they thought it was the pressure switch on the pump but that works fine, the codes that came up are p0628 and p1272 anyone got any suggestions as these 2 codes are to do with the pump.
