Changing battery positive pole sparked . Engine starts but it immediately gets off. Still have the lock symbol on the dash .

The security, antitheft or lock picture/icon is a visual indication that something in the car's antitheft system is failing. In most GM cars and trucks there is a hidden system that most people are unaware even exists. From the moment you put your key in the ignition, there begins a constant line of communication between your key's security chip or transponder, to the ignition's lock cylinder, and then to the car's TDM (Theft Deterrent Module). These 3 parts are in CONSTANT communication. If the key is in the ignition, then these parts are sending signals to each other. The security light illuminates when that signal gets broken, even just for a second. When the signal breaks, the car misinterprets this as an attempt at theft and goes into antitheft mode. The car thinks its being stolen or hotwired because it is not getting that signal from YOUR specific key. This is why the security light turns on and shuts down your vehicle. This link explains it pretty well.

THIS IS YOUR ANTI-THEFT DEVICE. There is probably a problem with the cars computer. A mechanic can reset the system.

You can try this. It usually always works:

Put key inignition and turn to on position (don't start) Now wait exactly 10 minutes. The light will shut off and you must start immediately after light turns off.
This resets the system.

Did you check the battery an connections , does the engine spin over when turning the key to start ? Light's work on the dash with key on . Is the SECURITY light on or flashing ? If the engine does spin with the key in the start position , is there spark ? pull a coil an see if there is spark ! If no spark , could have a crankshaft position sensor problem ! Do a fuel pressure test . etc... This is a very complex electronically controlled vehicle , you should consider taking it to the dealer !

Do you get any lights on the dashboard turning on when you turn the key to run/start positions? Do you get any noise from the starter/solenoid when you turn the key to start? Do the headlights come on when you turn the light switch on (Could you have a dead battery? Check it.) Unlikely spark plugs and power window have any connection. More likely something else happened in between those two events. Try removing negative battery cable, keep off for 10 minutes, then reattach and try starting the car. If you have a diagnostic code reader, attach to the diagnosis port under the dash and turn the ignition key to run position. Read codes and see what the computer detects as the problem.

give me a example of a reemdem code

Everything is supposed to go off in the start position. You would have power to the engine computer and other components to start.
If the engine is not locked up, it could be the starter or a bad connection with one of the battery cables.

Not sure if I can help but will need the year and model of your vehicle before I can even try...

check connections from the battery to starter if ok tap on the starter with a hammer as a helper starts the engine if it starts replace starter before you do dose the key turn all the way forward normal starting position? reason i ask is why did you replace the ignition cyl lock?

Try unhooking the battery, turn key on, leave door open, then connect battery, start engine immediately. The battery saver module thinks it's saving your power!!

HI.

Follow this step to keep running your sunfire.
1 - Be sure the battery is full charged.
2 - Is better if you put a battery charged
3 - Turn the key to run position and tray to start the car and leave with the key in run position,
With a watch let pass 10 minutes no less. you gonna see the security light flashing and stop flashing after 10 munites.
4 - After 10 munites turn the key to off position during 30 seconds, with watch on your hand, OK.
6-- After the 30 seconds try to star the car

I hope this solve your problem.
Please letme know.

Thank you for use fixya.
