Saturn sl2 automatic...put a starter in..still won't start..all dummy lights up and battery is good...go to turn the key and nothing...help..

sounds like no start power to the starter
unles it is stander then the clutch switch is bad

did you check battery could be death.Gas pedal is moving,under steering wheel any wires damaged.It is full park position.

You'll need to crawl under the car and check for power on the small terminal of the stater with the key in the crank position. Knowing if you have power there will help to give you a direction to go in. If you don't have a test light or a multi meter, you can jump the large wire at the starter to the small wi at the stater with the key in the off position. If the starter works than you'll need to focus on wiring. If the starter doesn't work replace it.

Could be a bad alternator.. It may not be holding charge. Or your starter could have failed.

Though I've had the same problem and it was a dead battery in my vehicle. Had enough power, but to keep the car on..

If it is an automatic shift you should have a neutral safety switch between the key switch and the starter. I would check that and for power at the starter when it fails to crank.
If it is a manual shift there is a switch on the clutch pedal or linkage.
It may be tough to find until you can duplicate the problem on demand.
Could also be a dead spot in the starter or solenoid.

Hi Vernon, There could be a number of different reasons why your vehicle is failing to start. The battery voltage could be dropping during start and become unable to engage the starter motor to turn the engine. You can check this by trying the key with the head lights switched on. If the lights become very dim, you'll need to check the battery, meaning clean the terminals and then try to start with a jump from another battery. If you achieve start up and it fails again the following morning, you will probably need to replace the battery. There could be a problem with the starter relay or a loose contact for the starter motor, most lik3ely the one connecting to the soliniod. It would be good to know some additional information, such as does a clicking sound come from the starter when engaged? Is there a perceptible drop in voltage output when the starter is engaged? does the enine turn at all? Try what I've suggested and if that does not solve the problem answer the questions and let me know anything else which you may think is relevant. Regards John

If you can locate the starter,tap on it with a hammer a couple of times then try to start up.It may take several tries but it should work eventually because a starter doesn't usually fail 100%.If you can't locate it call around,someone will tell you for free because they want your business.Dealer,shops,whatever.Good luck!

the ignition maybe bad are the car is not all the way in park also check the battery to make sure it has a good charge and it does not have a bad cell in it and the terminals are clean.

It would be hard to guess but a simple diagnostic would be to use a 12v test light and see if the starter solenoid recieves a 12 v signal while turning the key. If it lights, the starter should turn over. This also gives you the oportunity to check and verify all electrical connections at the starter including the large orange fusible link wire at the large battery terminal.

try having someone tap on the starter with a hammer or breaker bar while you turn the ignition. if it engages the starter then theres a problem and needs replaced. if not message me back and i'll help you trouble shoot further
