My son's car got this code and I we have been trying to figure out how to fix it. The car cranks but will not start, can smell gas like if it's leaking when cranking. Checked for fuel leaks and found none. So far we have replaced the fuel pump motor and filter/screens, new fuel filter, the fuel pressure sensor that sits at one end of the fuel rail has been replaced with a new one, the connector that connects to the FPRS has been replaced. And now the driver control module that sits in the trunk near the inertia switch has been replaced with one we picked up from the wrecking yard just to test it against the one that came with the car. We checked fuel pump relay fuse and it's good, also checked ignition switch fuses and they were good also. Not sure if it could be the CCRM or I'm thinking maybe the injector connections that connect on each injector. We sure could use some advice or input on this.

Thanks

This could be but that code is telling you that the fuel rail pressure sensor does not have the correct voltage. Since this does not start either we need to confirm the fuel pressure is correct.

Here is a guide that will help with that:

I attached the info below on how to test this. Let's run through this testing and let us know what you find.
