02 olds alero no start system shut down

Where did you try to by-pass at , with the 2000 ohm resistor ? Is the SECURITY light lit on the instrument cluster ? Probably has another problem other then the key . The anti-theft system in your vehicle can not be by-passed by using a resistor .

The Passlock™ System is provided in order to prevent vehicle theft if the ignition lock cylinder is forced to rotate or the ignition switch is operated while separated from the ignition lock cylinder case. If starting is attempted without authorization from the Passlock™ System, the powertrain control module (PCM) will disable engine starting. Start disable may be in the form of fuel disable or starter disable, depending on engine application.

Your best bet , take it to a qualified repair shop . Before you render it unfixable . (cost to much )

Whr is my fuel pump reset button on my 2003 grand am? Its security lock, it wont get any fuel. It cranks but wont start. Not getting any fuel. First time ever happening

There is no reset button.
The problem could be the anti-theft system which would knock out the injectors and spark to the plugs.
If the security light is staying on, the problem could be the chip in the key.

I have an 2004 chevy impala that has gas a new starter, new switch ignition, and new fuel pump installed. Why is my car still not starting when I go to crank it up?

Sixty years ago my daddy told me an engine needs four things to run:
  1. Fuel
  2. Air
  3. Compression
  4. Ignition
Air is generally a given, and you can hear compression--the sound the car makes while cranking, the rhythmic sound.

Fuel: Crank it for a bit and then remove a spark plug. If it's not wet, there's no fuel. Possible clogged fuel filter, blown fuel pump fuse, or fuel pump is disabled because automotive security thinks you're using a fake key. You can also test for no fuel by getting an aerosol can of carburetor/throttle body cleaner and spraying it in the inlet while someone else cranks the engine. If it runs as long as you are spraying, there's no fuel.

Ignition: Take off one spark plug wire at the plug. Insert a plastic-handled screwdriver into the wire-end. Hold the handle so the screwdriver shaft is within 1/4" of any engine part. While someone cranks the engine, you should see a blue spark jump from the screwdriver shaft to the engine if there's ignition.
