I tried changing pmd module with a spare I keep and still.does the same thing. Fuel filter is a week old, fuel pump is working. Checked all vacuum lines and they are good

Hi my name is ***** *****
Do you have a scan tool to read codes or data information? Does it crank along time before starting ( 4-8 seconds?)
Was there any metal particles or glitter type rust in bottom of fuel filter housing?
Have you disconnected anything else to try and diagnose this concern? ( cam sensor on top of the pump or crankshaft sensor?) This engine will start and run with either of these disconnected for diagnostic purposes , but will not start with both disconnected at same time.
Is this truck a manual or automatic transmission?
