Engine will not start but will roll over fuel pump works

Welcome to 2CarPros. Before you go too far I would do a few tests to be sure you have spark and fuel. The pump can be running but not supplying enough pressure.

You say the CEL is on but you don't get any codes, what scan tool are you using? Some will not retrieve OEM specific codes.

Those can be touchy sometimes in how they work. I would do the spark and fuel checks, you can usually get the tools as loaner tools, be prepared though, if you've never used the "Free loan a tool" system, they have you pay full price for the tools and then give you the money back when you return the tool in the same condition. Oh a quick check that can help you faster is to just spray some carburetor cleaner into the intake and see if it reacts, if it fires and runs a bit you have spark and the valves are in time. If it does nothing you probably don't have spark.
