Sound like a starter go to bad or died. You can do a few tests to diagnose a starting system problem without
any tools or measuring equipment. Turn on the headlights and start
cranking. If lights go out, you probably have a poor battery cable
connection that is impeeding the flow of current. Start checking battery
posts and battery cables for tightness and corrosion. A very thin film
of oxide between the terminal and cable clamp can choke off most of
current. Clean battery posts and cable terminals. Make sure all
connections are tight. Also check connections to the starter and
solenoid and engine-to-chassis grounding cables.
If headlights continue to shine brightly and nothing happens, voltage
is probably not reaching the starter. Usual suspects here include a
problem with the park/neutral or ignition circuit switches.
If lights go dim and the cranking action is sluggish, first suspect a low battery.
Starting problems especially in cold weather on a system that worked
well last summer can often be traced to a weak battery. Sub-zero
temperatures can cut a battery's amperage output by more than half.
Check out the battery condition. If the battery checks out okay, look
for a locked or dragging starter, a starter with high internal
resistance, worn brushes or open circuits in starter's windings or
armature. Additional details in this link:
