1993 Ford F150 - Where to begin

Charged up battery it started up drove to gas station and back home turned it off and tried to start it up again and it would not start, it’s not the battery it only a year old, what should I look for.

I would almost bet that it is the battery. They don’t like to be run down .

Measure the battery voltage when at rest and when cranking the engine, the voltage values may indicate the problem.

I have taken dozens of discharged batteries home to use in old cars and RVs, they recharge just fine. The battery in my car today came from a 2008 Chrysler PT Cruiser, it was removed in 2008, I recharged it this year and installed it in my car.
