Hi, my name is ***** ***** you for your question.
Start by clean and check all battery cables,,starter cables,,cab grounds and engine grounds.
Normally there are two starter solenoids, see if you are getting power to S terminal at starter while in crank position,,if you are you need that starter solenoid.The internal contacts get worn and cause this issue here.
If that checks out okay follow S terminal wire back usually to firewall for second solenoid or relay and replace that one.
The other things that can cause this are neutral safety switch/clutch switch,key switch.
Thanks
