Ok. Well. I read somewhere that a bad pressure sensor can cause similar issues so I tossed a new one in and also changed the fuel filter even though it had just been serviced before all of this happened.

Now, I have a single code for DPF temp sensor module and that’s it.

Insite reads:

Fuel pump actuator commanded current: 0.00mA
Fuel pump actuator duty cycle: 5%
Fuel pump actuator measured current: 62.5mA
Fuel pump actuator position: open
Fuel rail pressure commanded: 5228
Fuel rail pressure measured: -19 to -36 (it fluctuates)
Fuel rail pressure rationality sensor: -514
Fuel rail pressure rationality sensor voltage: 4.55v
Fuel rail pressure sensor signal voltage: .5v

It will crank but will not start.
