Detroit 671

[ducaticorse]

I drove this low mileage truck from PA to east ct 2 weeks ago stopped for tires.. The shop started it up, and said it ran for 20 minutes than shut off on its own, Then ran real rough when started up again. Does not have a heater block fires up cold with a shot of either. I'm new to diesels. Any thoughts? I have to go there tomorrow to bring it back to Boston, and would like to not have to push it home.....

Water in the lines? It has fresh fuel....

Could be a number of things, clogged injectors, air in the fuel lines. Was it extremly cold when it was started? Maybe the deisel gelled up.
