What should I do if my Cummins ISX wont run?

Start it up, run for 10 seconds or so (until the ecm recognizes that the oil pressure isn’t coming up I suppose) then shut down. Low on coolant, same thing. Should have code for low coolant or oil pressure if that was the case i would think.

What are some common Cummins engine problems?

What causes low oil pressure?
