2003 grand am no start, will not turn over and has no security light flashing.

Looks like a car alarm feature not ignition problem.
When my vehicle is flashing and will not start I have to push my key fob unlock button. Do you have a key fob?

Turn the key to the on position, leave it on until the security light stops flashing. (About 10 minutes) turn key off, then try to start. If it starts it's a bad body control module. Google override directions.

I had a 2000 Grand Am that did the same thing with the security light a couple of times. If I remember correctly you need to turn the ignition on for like 10 mins and then turn it off and it should start. I believe it tells you what to do in the owners manual if that doesn't work.

leave the key in the ignition, turned to 'run' (just before the crank position) and leave it there for about 15 minutes-the security light will then stop flashing-so NOT turn it off, turn it to crank and start the car. You have a security module that is not seeing the same resistance in the ignition switch as it expects, meaning you will have to either replace the ignition switch (expensive) or bypass the module (easy and inexpensive)-I have done lots of these, requires about 15 cents worth of parts and can be done in 1/2 hour.

Check to see if you have a computer chip on your key. Chances are that the computer chip or the reader in the ignition keyhole is not reading it properly. If you leave the key on, engine off, for 15-20min. that security will reset and the light will go off. Turn key off and now try to start engine.

sounds like you need a new ignition switch the pass lock is screwing up common.

Hi. I have a 99 Pontiac Grand Am. I've had that problem before. All I did was...whenever the security light would flash...and the car wouldn't start...I would take the key out...and just sit there and wait for about 10 to 15 minutes. Then the red light would stop flashing....and the car would start. That would happen about 2 times a year. Now I'm having trouble getting it to start. It's trying to...but won't turn over. My mechanic put a new computer....but now he doesn't know what is wrong. Please help. Thanks.

the security light will flash and disable the fuel injectors preventing the car from starting, if it thinks that it is being stolen. its easy to fix. set the parking brake to turn off the automatic headlights. next turn the key to the on position and wait ten minutes. the security light should stop flashing. then turn the key off and this will reset the security system. it should start immediatly afterwards.

Turn key on , let security light flash for fifteen minutes. Take key out and press reset button and put key back in and start car
