starter is full of water
clicking noise when trying to sart engine usually indicates a flat battery.if the battery is not the problem ,the starter motor needs repair.
check if your battery is low than usual ..might be alternator problem
Does the engine turn over and then make the clicking noise while trying to start, or does it not do anything but make the clicking noise when you turn the key. If its not turning over at all then it might be a battery problem, Try cleaning the battery terminals, and/or charge the battery, Could also be the starter solenoid, but start with the battery first.
Engine Seized?
Battery, starter, starter relay solonoid, or a charging problem i.e. alternator or voltage regulator causing battery to discharge. Or bad battery cable connection or dirty or loose battery cable connections can cause this problem. Need to investigate & narrow it down.
Low Battery
The Battery is shot and you need to replace it.
AnswerIs the clicking sound from the engine? Try to check the oil.If this is happening when you try to start the car, it is most likely a weak battery or a bad starter. Oil would not have anything to do with this problem
you might have slung a rod.
A clicking noise in the engine of a 91 Ranger could indicate a problem with the valves. A valve lifter in the engine may be worn or stuck.
Weak battery? Loose or corroded battery cables? Starter solenoid?
could be bad cells in the battery, but my bmw ended up having a seized motor, starter was engaging and clicking because it couldnt turn the engine. try putting a socket on the engine crank pulley to see if engine will rotate
