Mystery problem starting my car after alternator replacement? Fuel pump switch?

(1999 Ford F-150 Lightning)
in Fallbrook, CA on July 17, 2010
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.
