CUMMINS ISX WON'T STAY STARTED AFTER IT WAS SERVICED

Boss said. Check the filter under the hood. To see if you got air bubbles in it. If you do its not completely primed.

But he said it different with way more words. So this could be bad advise. In my opinion and that's all it is. If the oil is full and not leaking any where.
Open the pet #### and drain the fuel. Close the pet #### Pump the primer a 1000 times. Or bump the key on. But don't let the engine turn over.
Honestly I don't know jack about desoal. But on a car. If it not getting fuel it can only be some many thing.
Sounds to me like it chocking out. But I don't know how that would trAnslate into desial talk.

 

Which fuel filter? If its the one right before the injection pump I'd think twice about bypassing it. Those pumps and the fuel injectors need that fine filtration or you'll take them out real quick. If its the filter before that one you should be fine to get home but the fine micron filter right before the injection pump is going to plug up much quicker doing all the filtration.

 

The bypass is only to get off the side of road and to parts store or T/stop to buy new twist on filter clear top.

 

So your Davco filter had a cracked dome?

That's on the place where you had it serviced.

Wonder if they used the right tool.

 

They could F up a hot dog.

 

That is your fuel / water separator housing that's cracked.

Cummins have an electric prime pump, it's REALLY hard to lose prime unless that pump is bad, and in your case it's not.

You had some total rumpkin working on your truck is all.

They owe you a filter housing too.
