Vantage V8 fuel pump issue. Fuse vs Fuel pump driver module

Hello all.

I am having issues starting my 2007 V8 Vantage Manual.
At first the dash displayed "check battery disconnect switch" which I made sure was not activated. I also changed the battery. When i start the car, it cranks continuously but does not start. The dash displays there is no fuel in the car, however the tank is full (I just put in 5 gallons and topped it off)
I ran a diagnostic at my friends shop and it states the following errors:

P1233: Fuel Pump Driver Module off line
U0001: High Speed CAN communication BUS

It seems like there is a problem with the fuel pump, seeing that the car is showing no gas and the p1233 error. Is there any way to determine if this could be a faulty relay or fuse before I go ahead an buy a new fuel pump module? I unfortunately do not have the fuse diagram. Does anyone know what fuses and relays are responsible for the fuel pump system?
Also any idea on how/where to access the fuel pump module?

Thanks in advance

Don't confuse fuel pump with fuel pump driver module.

You should see if someone other than a friend with a shop has better skills or at least more knowledge of the vehicle. What's the history and how long has it been in this condition?

Fuel pump module is not sending its monitoring signal check to the PCM. Read the attached OBD2 info, check fuse F9 in trunk, see attached circuit diagram. FPDM is hard to get to, see picture.

Wow, thank you so much for the information!
With the code my car is giving, I am assuming either one of the fuses/relays is bad, or the actual Fuel pump driver module is bad.

I will start by checking all of the fuel pump related fuses:
-Fuse F9 in the trunk, Relay #2 in the trunk, and Diode#1.
-I also found some fuel pump related fuses in front of the passenger side seat (Although not labeled for fuel pump driver module - but the fuel pump itself): Fuse #47 and 74 under the pass side footwell are for the fuse pump.

If none of these are the culprit, my next step will be to replace the Fuel pump driver module. Does anyone know if this requires programming by the dealer? Unfortunately, the nearest dealer is miles away and would be a costly tow....which is the only reason I am trying to get the problem resolved at the shop that the car already is.

I wonder if the error is similar to those found in Ford's:

Same code found in F150 & Expedition, and same symptoms (Crank, No Start P1233)
As this year vantage is from the Ford years, i'm just curious if this could be a similar issue (even though our FDPM is not located externally as in the Ford)

Do you still have the "Check battery switch" msg in the dash? You have to resolve this issue first otherwise fuel will be cut from priming and injecting. You also have a CAN bus fault..I would track the battery switch msg and CAN fault.. It might lead you to replacing the FPM, but at least you would have been faulted guided into doing so.

First make sure the batt switch is passing the voltage through the switch and not just on the stay alive circuit feed... And then with the batt connected, check the CANHS and CANLS voltages in pins 3+11 and 6+14 of the diag port on body and 6+14 on engine. Then with batt disconnected check the resistance through the CAN circuits and make sure your at 60ohms.

If all checks out, check the voltage/ground/CAN at the FPM and confirm circuits are good. You can bypass the module(not for long) and confirm the issue is the module if you can prime the pump and get fuel pressure.
