Engine shuts off after releasing ignition key

1999 Samsung MX225 (Grey Market Machine for U.S.) . Has a Cummins engine model B5. 9-C, serial number on engine is 2623070.

Here is my issue. When I turn the key to crank the engine, the engine starts fine and runs fine, but, when I let go of they key to the run position...………...engine dies.

I was thinking it could be the following : 1. fuel shut off solenoid 2. Step motor 3. ignition key switch and lastly 4. bad computer (hope not) ?

Any help is appreciated.

I don't know the machine and likely few here do either. Any idea of the year of manufacture, hours of operation, serial number of the machine and maybe a photo of the fuel side of the engine to give us a place to start?

I see where TPG is going with this one...the pump solenoid might have a black wire (ground) a red wire (run) and a white wire (pull in, hooked to starter)

If the white wire gets power it will run but if the red wire is not also getting power it will not continue to run once the starter is released.

That's all well and good but what controls the solenoid that controls the red wire to the latching coil? It it computer driven?

The fuel shut off solenoid has a Red, white and black wire that is on the fuel shut off solenoid plug end.

The solenoid has this stamped on it : Woodward 5267132 , 24VDC , 28-18. Another number on a white label (looks kinda like a bar code label) stick on label is : 5267132.

serial number for the excavator is : FCY1589

I can get pictures of the engine / fuel pump ect. if needed.

I bought this machine from United Rental in 2005...………..has been a trouble free machine. Although it is a Grey Market machine, parts are still available through ROMCO Inc. a Volvo dealer.

If I remember correctly...…………..….99% of the parts on this machine are interchangeable with a Volvo EC210B. I would have to go down to the shop to verify that but I think that is correct.

I am no mechanic per say...……….…...the dealer (ROMCO) told me on the phone something like this : When you crank the engine, the shutoff solenoid gets 24 volts to it. when the key is released to the run position the fuel shut off solenoid then gets 12 volts to keep it open.

???? any ideas if that is somewhat correct ?

Black wire = ground
Red wire = hot with ignition (hold coil)
White wire = start signal only (start coil)

Check your fuse panel for a blown fuse on the ignition side. I have seen that a lot with these solenoids.

I’m not aware of any that change voltage. It has 2 coils, hold and start........start coil pulls the rod when you crank the engine. The hold coil holds the rod in run position until you turn the ignition switch off.

Ohm the solenoid or apply 12v (or 24v if 24v machine)

Black is ground
Blk to Red should not be open
Blk to White should not be open
Red to white should be open

Maybe the HOLD coil operates on only 12 volts ?

Is this while trying to crank the engine? or with the key switch in run position , ect ?

Thanks
