Is there any codes to pull ?
I think 2005 is of one of the best years for the D Max engine and fuel systems. That and the 2006 year.
Maybe someone with knowledge on these systems will jump in and give You the word.

Thank you for your response we figured it out. We pulled the one fuel injector back out cleaned it out more oil on the Injector and did the ice pick truck on the Injector. Put it back in and it worked..thank you for your reply and hope this info will help other diesel owners
