STARTER WONT ENGAGE ONLY CLICKS UNDER HOOD STATER

auto transmission or STICK???????????????\
all fuses test good?
what does turn over mean to you?
there are 3 answers
the starter spins all by itself and turns over,
if lucky the stater can even turn over the cranks shaft, called actual cranking over .
we say it will not crank or it does.
or we say
the starter cranks fast and he engine and will not start and run
or it may start for 3 second and stall ( a classic IMMO trick)

if the starter spins the engine robustly and fast why the new battery>
must be a no crank engine,(silent starter.,clicks or chatters or sound like bombb under hood a huge giant BANG< a seized engine,.
this is 10x more easy than a dead engine for sure.

1. :battery drained. so charge it.
2. battery load tests and charges fail the battery is bad
3. so battery new ,failed to help cranking. sorry I cant hear it. sure.
4. crank not in failing Park but now in Neutral , works?
5. ok all that fails. must be bad starter. WE HOT WIRE TEST THEM.
6. some rare cars the IMMO even cuts starter dead, not just spark/fuel. so is the IMMO happy light glowing or not.

FUSES GOOD
iMMO LAMP NOT ANGRY, (FAILING)
SCAN pCU, SEE IF THERE SAY BATTERY ERRORS ETC. DTC CODES.?
CRANK IN neutral not just park.
HOT WIRE THE STARTER.
JUMPER CABLE CRANKING WORK.?

OK FOUND IT YOU DID DOING ALL THAT.

Alternator,check fusible links,

lower power, make sure battery is charged , and or starter seloniod is not responding to power, some are mounted and part of the starter,and some are located on firewall under hood. ,not knowing what kind of car you have makes it a little hard .

Had the same problem two weeks ago. Changed the starter and everything is fine.

Did your starter have the Solenoid on it or is yours separate and mounted on the drivers side fender under the hood? The Red wire from the battery will go to the solenoid, then continue on down to the starter. It is possible that this part is faulty.

Be sure the connectors at d battery are ok. Check for broken, loose or disconnected wiring @ the starting unit, check neutral start switch, ignition switch n starter solenoid. If all these are eliminated, it might be that the starter motor pinion is jammed in flywheel ring gear.

Spin manually the engine crankshaft.

Your starter motor is likely bad, but before you remove the starter, take the battery and get it tested, you may have a bad battery, just because the lights and accessories work doesn't mean that your battery is not underpowered under a load. If the battery checks out o.k. remove the starter and have it tested at your local parts store. good luck.

Have you checked or replaced the main fuses under the hood. If you have, check the stater wire to see if it maybe broken somewhere.
