My truck turns over but will not start? on 2003 Ford F-250 Super Duty

The fuel pressure reads under 45psi and the mechanic said its the fuel pump and possible high pressure oil pump. Does this sound right.

Could it just be a sensor?

Codes p0336, p2290, p2291 came up in the flashpaq and we replaced the crankshaft position sensor, fuel pump and housing and fuel regulator. I dont know what parts to change for these codes

YES IT COULD BE ICP OR IPR BUT THESE ARE COMPLICATED ENGS AND REQUIRE SPECIAL TOOLS TO DIAG AND REPAIR.PO336 IS CRANK SENSOR PO2290 IS CONTROL PRESUR IS TO LOW AND P2291 IS LOW PRESSURE AT INJECTORS COULD HAVE A BAD HIGH PRESSURE OIL PUMP. NORMALLY THESE REPAIRS WITH EVERYTHING ARE AROUND 4500.00 PARTS AND LABOR
