I had codes checked, and they recommend MAF sensors. There is no change since replacing it. It has been difficult to start after fill up twice now and has rough idle. I assume that it is probably a fuel pressure sensor or fuel pump. What is the best way to determine definitively?

The fuel pressure sensor will make it idle rough and have low power, but can I ask what the codes are, so we don't go down the wrong trial in the repair process? This guide can help, and I have included the location of the fuel pressure sensor so you can check it out and replace it if necessary.

Not sure which code but I believe it was “running lean/bank 2”?

Sorry, I linked the wrong guide, I fixed it. Yep, a lean code could be the MAF sensor, here is the location, also go over this guide as well:

The MAF sensor is a normal service item BTW. Check out the images (below). Please let us know what happens.
