Mazda Repair Questions? Ask Mechanics for Answers ASAP
Hello, my name is***** sounds like there may be an issue with the injection unit. If the pressure will not increase due to an issue with the pressure regulator then this will occur. I would make sure that you have 55 psi of fuel pressure. Was this a new injection unit?
I am sorry for the delay in getting back to you. Did you still need some assistance with this?
