Hi my name is***** will be glad to try to help. Please post what fault codes are logged in the ECM. Also check for leaks or restrictions causing the fuel system to suck in air or starve for fuel. If okay I recommend doing the overhead and having the injectors tested by an injection shop. Let me know.
