Engine will crank but not start

A week or so ago I technically ran the car empty, technically in that gauge still showed 5 miles to empty but due to parking on an incline I suppose it was enough the car could not pull any fuel. Added some diesel maybe a gallon at most and car started perfectly. I stopped to get more fuel and drove home (20-mile trip) without incident or signs anything was wrong. The next morning the car just turned over and over but no start. I checked all fuses first and even replaced the fuel filter that I already had on hand just in case. I've cycled my ignition many times to prime and still no dice. More or less ignorant when it comes to cars, but I can work through most repairs but major engine repairs and the fuel system I've never had to address.
