B2650 stopped and won’t start

Fuel solenoids do go bad often. Maybe just replace it. Seems you`ve tried so many different things already.
Maybe this one just isn`t opening enough to allow the fuel to flow enough to let the engine to stay running.

I don`t think the continued injection bleeding is going to fix it.
Try a hair blower on the injection pump too. Nothing to lose at this point.

The guy will wear his starter out by the time he figures out he has a blockage at the filter etc. He should start at the tank and move forwards to the injector pump instead of hopping around. I know of a pro on-the-road bobcat (kubota engine) mechanic that RARELY cracks injector lines during bleeding on modern engines.

I was thinkin the same thing, that starter is being taxed so hard, that`ll be the next problem.

By disconnecting the solenoid,it's all about fuel flow.
The OPC "Operator Presence Control" can do some strange stuff!

So if it's pumping fuel after the bleeder screw, would that eliminate the solenoid problem and fuel shutoff problem?

Your shutoff solenoid should have a electric wire on it and should be around your injector pump. Like I said if you pull it out leave the wire on and turn key to on position not start and see if the little plunger moves in and out. If it does it's ok and probably air in system. Should be bleeders around pump also.

This looks like the solenoid.

2nd picture is solenoid..
1st picture is supply pump.
To add a bit: if the solenoid has 1 wire.. it means it grounds thru the body..
So the body has to be touching something metal.. for it to complete the circuit.

Great idea [to pull the solenoid and watch the plunger] and while we are at it -- do fuel shutoff solenoids require voltage (or ground if 2 wires) to shut fuel off ? Would removing the solenoid for a trial, as suggested above, actually OPEN the fuel flow inside the high pressure pump OR stop it? Just for my education.

Certainly finding squirts at the injector lines would clear everything in the fuel path including the solenoid wouldn't it?

It requires voltage to run..
And u cut voltage to shut it off..
Removing it will act as if it’s got voltage, your removing the plunger in the solenoid that push’s the control rack in the injection pump..

I ordered a backup starter just in case...

No I was saying the bottom of the first picture looks like it. And this is his picture so that's all I had to work with.
