I had surgery in February and my Ranger sat idle since then. With the battery fully charged, all it does is turn over. No fire. It is a standard transmission with about 60000 miles and a quarter tank of gass. Any sugestions?

All "crank, no start" conditions are approached in the same way. Every engine requires certain functions to be able to run. Some of these functions rely on specific components to work and some components are part of more than one function so it is important to see the whole picture to be able to conclude anything about what may have failed. Also, these functions can ONLY be tested during the failure. Any other time and they will simply test good because the problem isn't present at the moment.
If you approach this in any other way, you are merely guessing and that only serves to replace unnecessary parts and wastes money.
Every engine requires spark, fuel and compression to run. That's what we have to look for.
These are the basics that need to be tested and will give us the info required to isolate a cause.
1) Test for spark at the plug end of the wire using a spark tester. If none found, check for power supply on the + terminal of the coil with the key on.
2) Test for injector pulse using a small bulb called a noid light. If none found, check for power supply at one side of the injector with the key on.
3) Use a fuel pressure gauge to test for correct fuel pressure, also noticing if the pressure holds when key is shut off.
4) If all of these things check good, then you would need to do a complete compression test.
Once you have determined which of these functions has dropped out,
you will know which system is having the problem.

All ditto with what Hammer suggested and a comment on fuel.
I'm finding fuel to be the problem within six months with the crap the sell here
Now I'm marking gas cans when it was bought and using stabil a lot! Seasonal equipment that I forgot to drain or whatever almost always gives me a hard time.
If this ends up a fuel quality issue I've had fair luck with two products - SeaFoam and some periodic use of Techron fuel additive. I hate it that the dang fuel doesn't come with stuff to help but most doesn't.
You still need to know what the source problem is and get it running first,
