01 Dodge Durango Fuel regulator question

[MuleShack]

I have a self diagnosis on this vehichle (wifes car) with the symptoms being continuous cranking before vehichle fires up when cold and then a little rough running and then it runs fine after that. When it sits over night or in a lot for 8-9 hours then it acts up also. I replaces plugs and wires last fall along with the distributor thingy.

IF the fuel pressure regulator is the problem, IS this model able to replace just the regulator or does it only come with the fuel pump combo package?

It is the smaller V8 version (5.4 I think).

I am thinking about taking it in next week and trying to see how much is is going to run. From what I hear if the regulator can be replaced it will save a bundle and also dont want to be taken to the cleaners by the shop either.

Thanks for any info.

it is part of the fuel pump assembly. one way to check is if there is one fuel line going to the rail that the pressure is regulated at the fuel pump. if there are two fuel lines going to the rail than the pressure is usually regulated at the rail by a serviceable regulator

Thanks,

Is there a way to test the fuel pressure or do you need special equipment for that?

There should be a test port on the fuel rail. All you need is a pressure gauge with the fitting for that port. It is the bigger/common/standard port.
