When the truck started in the morning was it running rough?

Customer: replied 2 years ago.
It wasn't running rough. Put fuel in it and it started. But later today it stopped working again after I drove it, I stopped at sonic and it wouldn't restart. Wasn't running roughly or smoking either.

The engine would turn over and just not start correct? So the starter is working correctly?

Customer: replied 2 years ago.
it cranks.

The first thing I would check is remove the top fuel filter cap and make sure irbid still full of fuel. Next if you have a way to test for codes please do it and let me know what codes you get. When a vehicle just decides not to restart one day. It is usually the fuel pump, low oil pressure, Ficm module, or the EGR valve is stuck open.
