A crank but no start is either:
No fuel
No spark
No air
Fuel: As stated you perform the fuel pressure tests in the sticky
Spark: You verify 1" of strong blue spark at the plugs. If not then you works backwards towards the engine computer and the related sensors to determine why no spark
Air: Usually restrictions but electrical wont cause that except possibly the AIC, if this truck has one. Probably not the issue here.
Spark is the easiest and cheapest to verify followed by fuel pressure.

It doesn't crank now.After I had taken it to AutoZone and had them charge it, it would crank but not start.Shortly after that is when the battery was drained. In less than an hour it wouldn't even crank but the interior lights would still come on.

So what to do? Charge the battery and start the vehicle. Read the voltage gauge on your dash. It should be over 13 volts if alternator is working. If not, fix the alternator. If voltage with vehicle running it is above 13V, replace the battery. It is the time of year when they tend to fail and yours is old enough to be out of warranty.

There should be a 1" spark at the spark plug tester.
The fuel should have reach the nominal pressure and maintain it for 10 minutes.

Do not worry about air at this point. You can test spark with a $10 spark tester from Amazon or even get a decent result with a screwdriver. You can test fuel pressure with a $25 tester from amazon. You will also need a garden variety dc voltmeter which many already have. When your ready to test properly get back to us and we can walk through the process.

I am beginning to wonder if there was a big old sub woofer installed and the fuse went on it or a multi piece battery cable and one of them isn't hooked up. The description is a bit odd and seems incomplete.
