Problem started with truck sometimes cranking but not starting, then it got to be most of the time. Replaced the Fuel Pump Driver Module. After FPDM replacement I drove it a couple of weeks with it doing the crank and no start problem a few times then it got to where it would not start so I replaced the fuel pump. Now it cranks but does not start. It is coming up with these codes: P0453, P0462, and P1233.

So the last code it the issues, so you said you replaced the fuel pump driver module correct?

P0453 EVAP System Pressure Sensor High Input
P0462 Fuel Level Sensor Circuit Low Input
P1233 Fuel Pump Driver Module (FPDM) Offline / Disabled / No Power

You could have a bad fuel pump relay which powers the FPCM, at the FPCM remove the electrical connector and test the VIO/WHT wire while cranking it should have power, this guide can help you test it:
