Please this is a diesel engine, please can you provide me with any instructions relating to ECU signals for the fuel pump, also power and ground for the ECU terminal. Diagrams for power and ground.

The attached are the pump relay and the ECM connector as well as the control info. This truck was sold in the US but we never got the diesel version. As such our service information doesn't really cover it.

Well after scanning the car, I noticed a lot of U0 codes, if by some means you can sort out and send to me the Can High and Can low diagram, and the block diagrams for the modules, I can solve this problem.

These are the data lines for the US version, they should be close to the one you have. The OE doesn't list them like this. However, a U0 just means the modules are not talking. That could be as simple as a failed ECU or one of them shorted the network.
