Starter just clicking

NO CAR TOLD YEAR,MAKE OR MODEL NOR VIN#
BATTERY IS DEAD. WHY AND HOW WHO KNOWS?
WE CHARGE THEM USING A TOOL CALLED CHARGER

AND IF THAT FAILS TO MAKE OLD BATTERY CRANK ENGINE
THE BATTERY IS REPLACED. NOW.

EML IS CALLED CEL.SES AND MIL LAMP
IN ENGLISH IT IS CHECK ENGINE LAMP.
IT JUST STARTS SO THERE IS THE 1 KEY TEST DONE.
WHEN IT STARTS AGAIN
WE WHIP OUT THE OLD DMM,VOLT METER.
AND CHECK BATTERY LUGS FOR 13 TO 15VDC AT IDLE
BELOW 13VDC THE ALTERNATOR IS DEAD OR ITS FUSES BLOWN.

THERE ARE 6 CAUSES OF NO CRANKS.
FUSE] BLOWN
BATTERY DEAD (IT IS)
KEYSWITCH BAD (ST PIN)
PRNDL SWITCH BAD (AKA. PARK NEUTRAL SWITCH)
CRANK IN NEUTRAL NOW, DOES ENGINE START?
STARTER RELAY BAD
STARTER BAD.
OR ANY WIRE ABOVE CONNECTED.

OR BAD BATTERY CABLES OR LUGS LOOSE OR RUSTY.
THE BATTERY WILL BE DEAD IF ALTERNATOR FAILS
OR ITS BELT IS LOST OR SLIPS OR ALTERNATOR FUSES BLOWN
MOST CARS IF ALT FAILS AND WE DRIVE 30 MINUTES AND ENGINE DIES, FOR DEAD BATTERY./ NIGHT TIME LESS.
AT IDLE THE DAYS CHARGE/BATTERY LAMP MUST NOT GLOW.
IP CLUSTER LAMP

Take starter relay off have tested if good than starter needs replaced or bad wire con.

Short answer, your batter is bad. or is disCHARGED:
Long.:

wont crank?
no engine, cranks ,unless the starting system works.
unless pushed fast, like my car or i park on a hill and coast jump my car.(M/T tranny rule)

NO crank, is the true failure here:
slow Cranks are , bad battery , or a discharged battery , due to bad charging system or parked for 3 months or longer.

so ill assume its NO CRANK.
I turn the key TO START and the starter fails to CRANK.
the starter motor is dead. (key clue 1)
so i attach a set of jumper cables to my Caddy, running and this car
now cranks and RUNS (you left that out. above, huh? runs)

turnsover means nothing, because the engine starter turns over
and the engine can turn over and the engine can run,
once running the EFI system SUSTAINS runninng.
so there are 4 states there. (4 phases )

No cranks #1 reason to be slow , are a bad battery
so I charge that battery, and see how if it cranks , now?
it dont crank means a bad battery
it does work( crank) see how long it works.../?
if it dies again, or better, check the cars Alternator for by measuring
accross the battery terminals running , with any volt meter.
13.3 to 15vdc is a good alternator running the engine.
if NOT, the charge system is bad. (system)

On some cars the IMMO can block Cranking or for sure blocks
fueling after 2 seconds. So. watch the IMMO light on the dash.
Immo is the Immoblizer. option.

Anti-theft system has nothing to do with it . Battery cables , maybe , Park neutral safety switch possibly ! With anti-theft system problem you wouldn't a click or anything , that is if the anti-theft disables fuel or the starter . Plus the SECURITY light would be on if it were a anti-theft system problem . Your best bet , take it to a qualified repair shop that knows how to do starter circuit testing >
Starter Voltage Drop
How to voltage drop test starter motor circuit

And what's this identity anti theft system ? No such thing ! The vehicle has a content theft an vehicle theft deterrent system !
This system disables fuel not cranking of the engine. The VCM/PCM will not disable the fuel due to any BCM message for the remainder of the ignition cycle.
If the VCM/PCM does not receive the same password from the BCM as the last learned one, the vehicle will start and then stalls due to the Fuel Lockout.

change the wires that go to the starter i had the same problem fixed now with no problems

It's your starter

the rapid loud clicking sound is the solenoid on your starter motor. usually indicating that the starter motor is defective or the battery needs charging or replacing at this time of year older batteries tend to die due to the cold.

1 test battery, look at battery and see if it has a window on top if so see if it is green if not it most likely needs replacing, test by switching on headlights and then trying to start the car if the lights dim or go out when you turn the key this indicates the battery is bad, if the lights stay bright this indicates a problem with your starter motor.

I hope this was helpful.

have you had the alt checked.If ok have a load test done on battery it might have a bad cell

a single click usually means the starter. multiple rapid clicks while the key is in start position usually means battery...if battery bad, could be due to alternator, but you likely would have noticed a battery light on the dash while driving before.
