Can i unplug the anti theft system in my 1992 saab and my car still start and run?

Google or Bing it. Lots of blogs about disarming or disabling security systems. Is this a factory installed alarm? You will have to pick carefully, but there may be a saab story out there!
Prepare for a big learning curve. I'm happily too old to learn, but it looks like a lot of wiring there.

The dealer are the only ones that can disble the anti-theft device with the Tech2,but thepblemou hve ,it souns tome likethe Crank shaft pos sensor, common problem for that year model, agter you let the engine cool down a little bit the engine will start again.

anti-theft system needs to be reset

Hi Mark try spraying some starting fluid in the intake.You asked about putting petrol in the carburettor...your 1992 Saab has a carburettor? Impossible.That vehicle is fuel injected.Spray the starting fluid lightly or you'll flood the engine.

Make sure your battery is fully charged and check the teeth on the starter and flywheel.

The code is not on the radio
To get code go to intstant radio code uk

If your battery goes flat or you disconnected the car battery, your car stereo anti-theft security system will be activated: you need to consult your car/radio user manual to remove this lock and will need the correct security code.
Hope it helps: please let me know how you go!

Both Auto Zone and Advance Auto carry the plugs you need for your Saab....you can check on-line for the store nearest you...if they don't have them in stock they can order them for you and you can usually get them the same day. I have never had a problem ordering plugs for my 1997 Saab 900S nor for the 1997 Saab 9000 and 1999 Saab 900SE that I work on for friends.....hope this helps.

Jumpstarting cars with electronic ignition is not a good idea. Your car is also fitted with an immobilizer, hence the alarm going off. Get someone to drive you to a place that sells suitable batteries, and fit the new one. You should be fine.
