I have no power to starter

check for battery voltage at the battery starter cable with starter switch engaged , if voltage is ok starter at fault, if no voltage solenoid or cable at fault.

Could be issue with ignition switch or security system? If the starter motor won't crank, check voltage circuits at the starter. Usually two voltage circuits, one is battery voltage, hot all the time. The other voltage comes from crank position of ignition switch. That circuit could be routed through the neutral switch or clutch switch, depending on your tranny.

Any testing at starter make sure tranny is in park or neutral and the parking brake is set.

Make sure you have your radio code if needed otherwise the radio won't work after this. Disconect battry, Unbolt main wire from starter, disconect switch wire from starter, unbolt starter, remove starter, fit new starter, connect switch wire, connect main wire to starter, connect battrey, start a couple of times to make sure all ok, input radio code.

Have someone hold the key to start & tap the startermotor & solinoid To test starter. If start you will need a new starter motor

99% probably it is the starter.

hi.
it is a little awkward but it can be done.
if you go under the car with jump leads, connect the positive lead to the thick wire on the starter motor. connect the negative to the body or chassis.
the starter lead is connected direct to the battery so it will give enough power for you to open the boot using the button or the remote.

hope this helps

to check for sure try the following.
1 ensure the vehicle is in N gear position.

switch on headlight and then turn the key. if the lights dim it means that the starter has tried to start and the power of the battery is low thus the lights dim or got out. e.g. the battery is weak and needs charge or replacment.

if ligths stay lit then you most likely have a problem with your starter motor or starter circuit. a tap of the starter motor with a rubber mallet or a piece of 2x4 may dislodge and allow to start. if this is the case you may need a new starter motor,

i hope this was useful

p/l check your car battry power & your starter cable properly conected this switch

starter ground or the starter itself is bad

Check the transmission neutral start inhibit switch is not the cause of your problem. (try both 'P' to 'N' positions).
If the headlights work ok there should be enough power in the battery to at least make a solenoid type noise when start is attempted- so it may not be caused by a faulty alternator.
Check the battery terminals are clean and firmly attached to the battery,
Check battery is properly grounded to the chassis and motor,
Check that +12v is available at the starter motor engage solenoid when the ignition switch is held in the 'start' position - check any start slave relay operation.
If all above is OK, you may have a faulty starter motor.
