Wont't turn over

My 2003 Saturn l200 2.2 ecotec did this when the battery was dead. Put some juice on the battery, then the car came out of park, and I was able to remove the key. To the car, there's a vast difference between a sluggish battery and a dead battery. It may have enough amps to crank it, but it wont start w/out full output from the battery.

REPLACE IGNITION KEY CYLENDER/ WORE OUT

Make sure clutch switch or neutral switch if auto is making.

When you turn the key to start & the motor turns
or turns over that is the same thing as the crankshaft
turning you call won't crank

So you need to say my engine turns over but it will
not start

You need to check for fuel pressure & spark

Most likely you will need the help of a repair shop

shift interlock is not working at shifter key wont turn to come out unless signal from switch tells it is in park.

assuming the 2005 model year stil uses viper security systems...the chip in the key carries a magnetic resistance frequency. if the chip is damaged or corroded the frequency will change and wont engage the igntion. you can either get another key made (about 75 dollars) or bypass the ignition lockout feature.

In every likelihood have the Bendex of the checked up. It is not connecting the self starter motor with the engine crank shaft thus the whirring sound.

try locking your car with the key and unlocking it with the key, leave it for 30 second or so between the locking and unlocking , the car thinks some one has tampered with it

Check your battery if it is to corrodid it won't have enough amps to turn the starter then check the starter if that is all good check your ground you should have a main ground to the block and another to the body

Try Changing the fuel filter, if this does not work check for spark. Hope this helps you.
