Re: Hard start/no start DT 466

I had a similar no start problem with my 5.9 Cummins when I stopped to take a break in a rest stop. It would run ok on starter fluid but would immediately die after I stopped spraying. It turned out to be the shut down solenoid. Seems like it put the motor into "off" regardless of the ignition key position.

Thanks, I will add that to the list of items to look for.

Not yet, the weather turned to crap, I am hoping to have it moved by Thanksgiving. My satellite television provider doesn't supply Network television channels, so I don't get to watch much Football. I planned to build my wife a nice heavy duty garden wagon (I have four wheel-barrow wheels and tires) on Thanksgiving Day but it looks like I may be working on my bus instead.

Re: Hard start/no start DT 466

if you have to pull a handle to shut your motor down then you don't have a fuel shutoff solenoid but rather mechanical linkage (or cable) between the lever you pull to shut her down and the fuel cut-off on the side of the injector pump.

are you sure the handle is pushed all the way in?

have someone move the handle in/out while you look at the injector pump and watch the corresponding fuel-cut off lever move back/fourth. If it doesn't move, then that's your problem.

It's very likely to me that it's air in the diesel line. Follow the directions in the above post to prime the system and see if she'll start.

Yes, I do have a "fuel kill" pull handle. Thanks for that tip, I will certainly look into it!

Re: Hard start/no start DT 466

Happy Thanksgiving to all.

My bus is running, covered with tarps and parked for the winter. I ran the block heater and battery charger on it for the past 48 hours. This morning I checked the fuel kill pull-handle and cable, it was operating correctly. I then located the manual fuel primer on the injector pump. It is round, made from black plastic and about the size of a 12-gauge shotgun shell. It is also spring loaded so once pushed down it returns up to it's starting position automatically. The primer was easy to get to and very easy to depress. It took about 20 seconds to push it down 100 times and let it spring back up, the engine then turned over and fired right up, all while hoping on my right foot. Problem solved. Thanks guys, this Forum is a friendly and fantastic resource!

There should be no reason why it would lose prime in a day, week, or eternity as long as everything is tight. Maybe it isn't a big deal to you to have to pump the primer a few times every couple of months when you start it, but that does mean that fuel might be getting out or contaminants in so I would start figuring out where the leak is if I were you.

For what it's worth I hit my primer a few times if my bus has been sitting for a long time (10-15 pumps). I have an incredibly small leak and I know where it is. I really don't even think I need to hit the primer, but I do.

Re: Hard start/no start DT 466

The cold weather came in all off a sudden, which it tends to do this time of year. I am guessing that it was due to the cold weather and the fact I hadn't added any fuel stabilizer. I added enough to the tank a couple of days ago to treat what I estimated to be about 30 gallons of fuel. Today I idled the bus for about 20 minutes and then drove it a few hundred feet, I then backed it in to it's winter parking. I believe that sloshed the remaining fuel around in the tank enough to mix the stabilizer with the fuel and that the engine ran long enough to refill the lines and fuel pump with the treated fuel.

Re: Hard start/no start DT 466

Sounds like no fuel. While cranking white smoke should be evident at the exhaust. If not, then no fuel. Most likely the fuel cutoff. If in doubt, crack one of the injector lines and see if fuel squirts out while cranking. Go easy on the starting fluid as this can break rings and pistons if overdone.
