I checked the battery and it appears to be good. What else should I check? It won't turn over at all.
Sounds like the starter motor needs replacement. If possible have someone lightly tap the starter motor while you hold the key in the cranking position if the starter engages you will need to replace the starter. Also check the large wire at the starter ( this is the 12 volt lead directly from the positive side of battery) , the eyelet sometimes corrodes and or breaks causing a poor connection.

reach under engine and tap on starter with a hammer (careful!) while someone turns key...starter needs lube at Bendix solenoid.

On the firewall is the starter motor relay. There are 2 large battery sized cables to it, and 1 smaller ( 16 AWG ) wire that is orange or orange with a stripe ( forget the color, want to say white or tan ).
When you turn the key to the start position, check the smaller gauge wire for +12 V. The case should be ground. If you do not get +12 on the orange wire, try starting the truck in neutral ( apply the parking brake, chock the wheel, etc normal safety precautions ). Test for +12 V at the small wire. This is the output of the DTR ( Digital Transmission Range ) sensor or in common terms the Neutral switch. The start position on the ign switch runs through the DTR to the starter motor relay coil.
If you have a stick, the DTR is replaced by the Clutch Pedal Position Switch ( clutch must be pushed in to start ).
If you have power to this ( at the times the truck won't start ) next is to check the both battery cable ends to see if they are corroded and making intermittent contact ( not probable but possible ).

Hi Jose Ruppenschlager , I want to help you with your problem, but I need more information from you. Can you please add details in the comment box? do you hear any sound while trying to crank it over? a click perhaps? do the lights come on in the instrument cluster ( ie: engine, oil, etc...)?
Hi Pete, thanks for responding. I do hear a clicking noise and all the lights come on on the dash. The headlights work too but they are a bit dimmer than usual.
