A weak battery. There is not enough voltage to hold the starter solonoid in.
Wires connected to the starter incorrectly or defective ignition switch.
Start with the basics. Is the battery fully charged? Are the battery post clean and tight. If you answer yes to both of these and the engine will not turn over and you hear nothing, suspect the starter, starter solenoid, or ignition switch is defective.
Get a new starter. It's gone bad and is trying to draw too much power and can cause a fire.
There are two SMALL wires on the starter. They are connected wrong.

Batteries low. Starter's getting current but not enough.
Bad starter, bad flywheel/ring gear, bad starter/flywheel alignment.
