Do you have CAT ET or a service tool to test the engine fuel system? (Usually CAT ET program is the only one that can view all the parameters.)

Your problem is possible fuel injectors and if it is, you will still need ET to program the new injector trim files into the ECM.

You may also need special tooling to isolate the injectors from the pump for pressure testing procedures.
