SOURCE: anti theft dash light is blinking on my 1998 rodeo

I'm assuming its an original alarm or system that came from factory or dealer. When the light blinks is because the alarm is activated. Look underneath the radio the alarm brain might be there. There will be a label on it saying alarm or security system etc. Disconnect the harness to it and try operating your vehicle.

SOURCE: Unhooking Battery Cables

unhooking the battery won't clear the code it's still stored in the hard set memory go to shcucks and have them scan the computer ask them to see if the codes are cleared if not you can clear them they can't it is an OBDII car once you have cleared the problem drive it and see if it comes back, be sure to get the codes printed out before clearing the codes the mechanic will need them if it comes back, there are hard codes and soft codes soft codes can be reset by unhooking the battery but not hard codes. Don't bother with unhooking the battery.

SOURCE: chevy cavalier z24 theft system light on

This is a easy fix. Lucky just follow the procedure and your car will start. This is a theft system shut down.
The procedure is. Disconnect battery for a minimum of 30 seconds. ( one post is OK. )
Reconnect battery and get in the car and start as usual 1 time only. When it starts and stops letthe key just return to run position as if it was running. Do not shut it off and if you do you must stert the procedure all over again. i usually put on the emergency brake before i start and that shuts of the driving lights etc.
Just leave the key in on running position and go have a coffee. it takes 15 to 20 minutes for the car to recycle the system. When you come back to the car the flashing theft light will either be off or solid.
Try to start again. If it doesn't go shut it off and turn back on and start as usual. It will start and run and stay running.
The reason you have this problem is something electronic was disconnected whe the battery was hooked up. always disconnect the battery before you touch anything electronic and you will not have this problem.

Is there spark getting to the spark plugs ? Is there fuel pressure, check with fuel pressure gauge . Is there an anti-theft system light lit on the dash ? SECURITY light ? Can a scan tool communicate with the vehicle modules ? PCM , BCM , ABS , Air bags , etc... You should test before replacing parts ! No Start Diagnostic Basics EricTheCarGuy

If you have no spark try the ignition module, it controls the spark and if you don't have any and the coil is new its the only other option short of wiring or ecu!!

Check if equipped for anti theft system. Usually the anti theft will allow for initial spark and then kill the fuel injectors!
Disconnect the battery and have it recharged and tested, if it fails the test replace it. Use the key and manually lock and unlock the drivers door if the alarm is still set, There is a switch attached to the door lock that disables the anti theft. If the driver's side is defective switch you have to do this from the passenger door.

Hope this helps?

No start cranks but does not fire has spark. has fuel if bypassed by relay fuses good new fuel pump a year ago has fuel replaced battery froze, has prostart remote start, been in 8 years no issues 2000...


check to see if the security light or anti theft light flashes. if that is the case, sounds like the bypass for the remote starter may be causeing the no start by tripping the anti theft system. Remove remote starter and bypass system and join any cut wires back together that may be cut for remote starter. Try starting, if theft light still flashes leave key in the on position after attempted start for 15 minutes till theft light goes solid, turn off and try again. Repeat process for three times to re-learn factory theft system in vehicle. If problem still persists, then take to your local dealer to reprogram factory theft module in the cluster.

I have a 1997 chevy cavalier.it has good spark and is getting fuel but wont fire up or even sputter.theft light is on and is steady.


Try manually locking the car (with the key), on the Driver's side. Then wait about a minute, for the security system to reset and unlock it (again Driver's side with key).

92' Cavalier 2.2L 4 cyl. runs but has a miss coming from #4 cyl.


Matter not whether plug fires out of engine. Put it back in and clamp a timing ligh to it. If the light won't fire, you don't have enough spark to fire cylinder, hense miss.
