Cummins no start,(lift pump not cycling)

Hello everyone, I am working on an 2008, Country Coach Magna with an 600hp ISX.
I'm having a hard time locating where the fuel pump relay might be on this. I'm not regularly an RV Mechanic, I mainly stick to Trucks and trailers, but just hoping to help a friend out with this one. I'm familiar with the ISX, but being in an RV makes this an entirely different animal. Locating the correct fuses in this giant is tough.

Any help would be greatly appreciated

Does it have a rear start pair of switches in the engine area? If so that board should have 2 fuses on it...one for the starter circuit and the other for the lift pump.

This post is my opinion, worth what you paid for it.
Our ”New” ride...08 HR Navigator 45’. A nice upgrade after 14 years with a 04 Dynasty 42’.

Far as I remember, it only had a main power switch to disconnect the batteries. I will be able to look over it again tomorrow. Is there any other place I should look for fuse or relay?
Thank you for your help

To the best of my recollection on an 08 engine there should be a relay and fuse for the fuel pump on the fuel pump side of the engine somewhere around there fuel filter.
