I have a 2003 Dodge with manuel transmission that im having trouble with and can not find any one that knows the fix problems are.
1. Loss of fuel pressure for a split second, will go from 15000 psi to 0 and pick back up in a split second
I have replaced both fuel pumps lift pump and high pressure pump, Checked the injectors replaced the O rings and carbon dams.
engine scan does not show any codes at all. And still having the problem.

Has any body heard of this problem and if so what is the fix???

Thanks,
Coyote Man

 

What's telling you that it's going from "15k psi to 0"?, do you have a FP? Do you notice it in terms of the power that the truck is outputting? If not, are you sure the gauge is accurate and functioning correctly?
