Help identifying solenoids (fuel)

Hi All,

I am still a newbie.

I have a two terminal solenoid sitting on top of the back of the cummins 8.3L trubo engine. From what I can tell it manages the flow of low pressure diesel fuel. There is a line from the injector filter block before the injector pump and up to solenoid-1.jpg(see attached) then to two other solenoids/injectors(solenoid-inj.jpg) that are mounted on the intake manifold where the turbo pipe connects.

The first solenoid has two terminals neither were connected, I found what I believe is the positive wire laying next to it and cleaned/reattached. The second terminal is bent over and is I think soldered to the solenoid case/grounded.

Any thoughts as to what this does or ID would be greatly appreciated.

Might be a normally fuel open solenoid, maybe safety switch of some type.

Hi all, I pulled the air intake off and the two what I thought were solenoids are actually electrical connectors to the grid heater and the fuel solenoid provides low pressure fuel when the starter motor is engaged below 50 degrees for cold starting.
Thank you for taking interest.

It would help if you said what year and model of your motor home is. It looks like the
same system I have on my 98 Dynasty and mine doesn't work until around freezing.
There are two large glow plugs in the intake manifold and they heat up and when the engine is turned over that solenoid directs fuel onto the glow plugs and heats up the intake air to help the engine start.

Sorry, 1994 Dynasty with a 8.3 litre diesel. Sounds like the same system, however, mine uses a grid heater instead of glow plugs.
