Please help me Dodge gods

I have a 2008 Dodge Ram 1500 with a 5.7l Hemi. It has 130,00 miles on it and I generally have not had any issues with it minus the usual clicking when starting cold.

Yesterday as I was in the bank drive-thru the truck died and refused to restart. It cranks fine but acts like it's out of gas even though it has a 1/2 tank. I pulled codes po171 and po174 Lean Bank 1/2. It will not start. Where do I start. I've searched forums and it seems like it could be 10 different things.

Thank you all who contribute in advance.

 

Fuel pump ?

 

Verify spark and fuel pressure.

 

How do I go about testing fuel pressure?

 

With a gauge. You can probably rent one from your local parts store. Should be a schraeder valve on the fuel rail for the gauge to screw onto.
