Mystery problem starting my car after alternator replacement? Fuel pump switch? on 1999 Ford F-150 Lightning

First the Alternator went out. I put a new battery in and even before I changed the alternator, the starter would spin but I could not start the car. Now 2 weeks after a new alternator is in, I have the same problem again with starting? This truck has always started at first asking until now? Help!

you need to check and see if it has spark and fuel. a fuel pressure guage will test fuel and a spark testor will spark condition. start there as you will find one of them is not working. Roy
