Is the key a FOB style ? Or have a security chip in it ? Did this happen after you replaced the battery. Some cars need to have a lot of electrical components reset if power is interrupted ( battery removal ) .

SOURCE: car wont start has power has fuel and starter

The security system is activated. It kills the injector pulse ( signal) and on some modles the starter. You will need to try to relearn the system. First try to start the car, leave the key in the run position for 10 minutes. Cycle the key off, then cycle it to the run position again for 10 more minutes. Cycle it off again, then back to run for another 10 min. after the last cycle turn it off then try to start the car. It is a 30 minute relearn. If this does not work you will need a repair shop to replace the passlock sensor. Good Luck

SOURCE: My 2000 Oldsmobile Alero does not start. It cranks

check for a good spark first, if there is none look at ignition circuits its more likley this part,
it could also be the car alarm the immobiliser shutting of the ignition ""stops it getting nicked?"
try resetting the alarm if you take off pipe to carb and there is fule pumping out!!! fule filter is "ok" for starting up on!!! take care working with fule!

make sure your cap and rotor timing is correct double check spark plug routes (mistakes happen). maybe your timing is off in general.

Car wont start


Could be the linkage between the lock cylinder and the switch, or the trick was just a red herring and had nothing to do with the problem.
Will it crank in neutral ? Do you have power at the starter ?

Try squirting starter fluid or ether into the carb. If it takes over you might have a blocked fuel filter. Then see if you have spark. Just pull the wire and connect to an old plug or get a tester. Make sure your hands are insulated. If you have spark then check timing. Could be the coil if there's no spark. Also could be a Passlock Sensor.

My 01 alero wont start when i turn the key over it doesnt even try to start. The security light is not flashing but it does stay on while trying to start it.


If you turn the key and you don't get a crank, it could be your starter or battery. Check all your fuses first. Make sure the battery terminals are cleaned and have a good connection. Check all wiring and make sure there is no damage. Let me know and we will take it from there. I am here to help in any way I can.

im just gonna take a stab in the dark here i understand that your security light is on try unlocking your door with your key sometimes you just need to reset the security. otherwise ive seen a security module go bad that may be preventing you from starting it.

My 2004 alero will not start


I have this problem all too often myself. Pop the hood, check to make sure the wires have not come undone. If they are on there securely, try and jump the battery if you have that option. Once jumped, it will give the battery more juice and you should be good to go. Please rate FixYa!
