Has anyone replaced the fuel pump?

Yeah, that looks like low voltage gremlins...
Also... it's a possible that a tired-out starter could draw too much current. Only way to check for that would be a bench test or maybe resistance check on windings. If removed the starter I'd probably just replace it at that point, especially if it has a lot of miles (100k+).

I completely agree with the way that you are thinking about this.
If you check the Voltage dip at the battery while cranking that will let you know that the battery is too weak or the starter is drawing too much power. And if you check the battery on a battery tester and the battery is good then I would just replace the Starter.
I replaced mine with a new Bosch starter at about 100K miles.
My Autel scanner has a built in battery tester and it will measure voltage as well. And its not expensive.

If the battery has to work too hard to generate the current to run the starter, that can cause the voltage to drop so low that sensitive electronic sensors and controls can't work right. So engine might crank, but if the ECU can't sense and manage fuel, spark, etc it won't run.

Follow up to this thread: Thanks everyone for the information. Although the battery was bought new less than a year ago, I brought it to the local auto parts store to get tested and charged. I then put it in the car and the car started right up! I then drove it for an hour and then re-checked the error codes. They all went away!
So the takeaway from this episode is that I think my wife may have left the rear door opened, which slowly drained the battery over night. Then when she went to start the car in the morning, the battery was drained just enough to turn over the engine but not activate the fuel system.
I actually think the rear door is a poor design anyway, because when you close it, you can't tell if it's actually latched closed or not. In addition, for us who live in climates with snow, 3/8" of snow on the back bumper will render the back door inoperable. That is also the same with the optional Land Rover running boards, 1/4" or more of snow on the running boards renders any door inoperable until you chip off the ice and snow from the running boards.
But in the end, everything is ok now, thanks.
