Hello, my name is ***** ***** I am a professional here at Just Answer. I have noticed that your question was not getting a response and thought I would see if you still need help with this.I apologize for the delay and I hope I can still assist you with this here.

Can you scan the computer system and see if there are any fault code setting and post back with the results and we can work from there?

One other thing, if you are sure you have good fuel pressure have you check the exhaust back pressure to make sure there are no exhaust restrictions?
