3 reasons either the starter is not getting power from the solenoid, solenoid is not getting power from the battery or starter is burned up.
Check the wiring for the starter, and the starter solenoid for problems. One of these could stop power from getting to the starter.
Remove starter and bench test See if you are getting power to starter
Check your battery terminals one is either loose or the grounds are bad.... On the firewall.... The clicking is the starter not getting enough power... No Clicking means no power or bad starter..Or you killed the battery(no power).. Google starter problems etc...
Ok, in what way are you getting no power to the starter? Do you have power to the headlights? Do they dim a bunch when you try to start the vehicle? Is the starter clicking but not starting? Will the vehicle start if you jump start it? All electrical problems of this nature should start with a load test on the battery, even if it seems fairly new. If it tests good, the next thing I would check is to see if the headlights dim when you try to start it. If they dim I would check the cable connections to the battery, then have the starter tested. If they don't dim you could either have a problem with the ignition switch side of things or the starter solenoid.
the starter isn't getting power or the battery is dead. do some tracing of the power and see where it isn't getting juice
You should check the battery if it is good. Try checking to see if the power is getting to the starter when you push the button if not it might be a falty relay .If power is getting to the starter (12 volt . If less check power going into your relay ) starter may need to be replaced or repared.
Does the engine crank over?
Check your Starter relay to make sure it is getting power if it is cceck to see if the decoder is getting power if both are getting power follow the starter wire to the starter selinoid if it is getting power then check all fuses and ground wires to make sure that it has good connection be sure to check the maix fuses also
Starter motor problems, charging system problems, wiring and connection problems between battery, alternator and starter. To many possiblities to list. If the battery is still charged and you need to jump the car to get it to start you have a bad starter. Now you say how can that be? it starts when its jumped? Correct the starter is drawing too much power"amps" and having a second battery "the jump" appx doubles the amount of amps to the starter allowing it to start. Replace the starter and problem will go away. Besides it wont take too long before a jump wont allow it to start.
First, make sure your all of your electrical connections and fuses are good. (battery cables are not corroded and cable to starter and ground are good) If they are good, it sounds like you either have a bad ignition switch or starter. You might try having someone turn the ignition switch to start position while using a multi-tester to see if you are getting power to the starter. If you are getting power to the starter, and it won't engage, chances are you need a new starter. If you do not have power to the starter, you might have a bad ignition switch. In certain circumstances you might try tapping on the starter with a hammer while someone is turning the ignition switch to see if it will engage. If it will, I would look to a bad starter. I have found that a majority of the time, a starter is the problem, not the ignition switch. Hope this helps.
Sounds like a defective starter, but check your battery cables and connections. Make sure you are getting power at the starter when you turn the key to the start position. Could be a relay too.
