Ah yes, but WHEN were the pictures taken? Perry Mason wants to know, lolYour shut down flapper looks good in pic#3 I would lean towards a fuel problem first, Former Wrench and Kshansen's post pretty much cover what you need to check first.... one other thing is these have to crank at a good rate to get going sometimes especially if they're a bit worn on the rings... so make sure you have some good batteries and jumpers on there right off the get go.
Okay, first question would be did you hear it running then quit?
I did not hear it quit, it was running that morning when I went to look at other equipment, when I got back over to it that afternoon it was shutoff and the fuel gauge was on Empty.
In the picture below inside the red circle is the latch device for the emergency shut down. Make sure that little lever is all the way down and the latch the cable is connected to is in the notch in the cam the little lever is in.
Moved the cable and everything appears to be moving on the outside.
You say it "might have run out of fuel", I'm assuming you have filled or at the least added a few gallons to the tank? Did you then remove and fill the fuel filters? Does this machine have a hand or electric priming pump? Some do, some don't have any.
I put about 10 gallons of diesel in the tank, didn't do the fuel filters because to get them I have to remove the top panel, didn't have the wrenches with me to do that. I'm not sure on the priming pump, I don't think it is electric if it has one.
In the picture below in the green circle is the fuel pump. It should have two lines coming out of the cover where you can see the one going straight towards the flywheel housing. One should come from the primary fuel filter. The other one is the output line to the secondary filter. Primary filter would be the one that the line from the tank hooks to, the secondary fuel filter would have one line from the fuel pump and the other line would go to a fitting in the cylinder head.
Once you have determined the outlet fitting for the fuel pump you could disconnect it and try cranking over the engine and see if fuel comes out, it won't pump a lot but there should be definite flow while cranking if there is fuel in the tank and the primary filter is full of fuel.
If you are not getting any fuel flow one of the next things I might suggest is to remove the inlet housing from the blower, remove the four bolts circled in blue and what ever is up on the top to connect to the air filter. With that off you will see the rotors of the blower. Do NOT touch them if someone is near the starter button! But try to rotate them by hand they may have a little free play but should not turn by hand.
I'll give those a try.
I could go on more but try doing that much and let us know what you find. Others may jump in with some more ideas and I have no problem with that but just wanted to approach it from what I might try if it was sitting out in my garage. A lot would depend on what if any knowledge I had of last time it ran and what care it had over the years. Like if this was parked for 2 years or more and fuel tank was full of water, then I would be looking at seized injectors. If that is the case I would make damn sure that emergency trip cable and flapper were in working condition!
Posted that then forgot to include the picture!

I don't recall Detroits as being hard to start after running out of fuel or changing filters, but then most of ours had the fuel tank mounted up high so it was mostly gravity fed.If you are certain it ran out of fuel it may be air locked, im assuming you have dealt with this kind of thing before. Detroits are notoriously bad when they get locked up I spend over 20 hrs once cracking all the fuel lines, rail and filters trying to get it to go. The truck left on its first delivery after a service and i got called out on the job site. That company used to haul construction supplies and build trusses. As soon as the driver turned the pto on to work the crane it quit. It was so bad i had to keep boosting the truck with my jeep to crank it
That would work just fine with these old Detroits, as they really only need to have some flow of fuel through the head passages/ The injector does all the pressure work! And the head passages should be more or less self bleeding with only the orifice fitting on the outlet to restrict the flow back to the tank.Seen one old guy had like a locomotive pump oiling can with a hose on it to fit the fuel filter, hand pump fuel until she caught, then shut it down and hook up the normal fuel line. This was on 6-71's that oil can must have held near half a gallon, lol.
Hey Guys, went to pick the machine up today, took about every tool we could think of that we might need (service truck isn't done yet). Got there, pulled the panels off the engine bay and went to take the fuel filters off, figured first I'd move the linkage on the emergency shutoff and try starting it before I started pulling too much stuff apart, reset the linkage and hit the key, fired right up! I was tickled pink!! It ran great loading it and then unloading it at the shop. It would appear someone used the emergency shutoff to kill it and it didn't "reset" afterward.
Glad to hear that! That makes two different Detroits that were "fixed" in just the last few weeks with nothing more than the twist of the wrist on that part.
Hope my crude little drawing back in post #10 help you understand the way that shut down worked.
Nice looking old COE IH there, guessing from the dual stacks it is running a V8 Detroit too?
Got nothing against a Comealong for sure! Just don't make the same "music" as a Detroit!Yeah, your drawing was helpful for sure! Actually, the COE has a 400hp Big Cam Cummins in it, I'd rather have it over a Detroit any day. Haha.
