Battery dead
The starter solenoid/relay switch is going bad. Eventually, it will just click and not start.
Dead battery or a bad connection to the battery.
Check to make sure you connections are all tight.
If it "clicks" when you turn the key,it sounds like either a weak battery of bad starter selenoid.
Your battery is dead. Turn your lights off next time.
Turn the key, just like in other cars.
Weak battery Loose or corroded battery cables
Could be the battery not charged enough, or turn your key and listen to any clicks within the engine bay. If you hear clicking sounds common from within? Get a buddy to turn the key inside while you gently hit the starter with a hammer a few times. It worked with my 70 monte carlo.
One of a few things depending on the click. If it makes consecutive clicks when you turn the key (click,click,click,click) then the odds are the battery is dead or in need of charging and there just isn't enough charge to fully engage the starter and turn over the engine. If it clicks just once, the selenoid is usually bad, or the starter is "locked" and will need to be replaced.
you need a new batt.
if there is a single click when you turn the key i would lean toward a starter being bad if there is multiple rapid clicks then i would lean toward a battery
sounds like the battery is dead, take the battery to a shop that can load test it
