Truck will not start anti theft will not shut off


The security light illuminates when that signal gets broken, or not seen at all. When the communication breaks, the car misinterprets this as an attempt at theft and goes into antitheft mode. (like it thinks it's being hot wired) The car shuts down because it is not getting that signal from YOUR specific key. This is why the security light turns on and shuts down your vehicle. It will either turn off the starter, or the fuel injectors. The vehicle may run for 2-3 seconds before shutting down. This link explains it pretty well.

Starting problems with my ML320 Mercedes.


Replaced a crank sensor on a similar model. Easy to do.
See if tach moves when cranking.
If it is starting and not just cranking, then shutting off, sounds like it might be an ignition switch. On some models, the contacts for start are different than for run, Start ones are good and it starts, when key turns to run, it turns off. That would be my next move to test.

Your vehicle security system is having an issue. Check your Owner's Manual for advice, or tow the vehicle to your local dealership to have them reset the security system for you.

MY 1999 FORD EXPEDITION SHUT DOWN,I THINK IT IS MY ANTI THEFT, HOW DO I CUT IT OFF AND WHERE IS IT ON THE SUV?


The anti theft light will flash fast on the dash if it's activated. You simply lock & unlock the doors to disarm it.

Check your inertia switch to see if it is activated. Press the rest button. Se owner manual to rest.

The control functions are contained in the instrument cluster. This module carries out all of the PATS functions such as receiving the identification code from the encoded ignition key and controlling engine enable. The instrument cluster initiates the key interrogation sequence when the vehicle ignition switch is turned to RUN or START.
The PATS uses the PCM to enable or disable the engine. The instrument cluster communicates with the PCM over the SCP network in order to enable engine operation. The instrument cluster and the PCM use sophisticated messages in order to prevent a theft. The instrument cluster and the PCM share security data (when first installed together) that makes them a matched pair. After this security data sharing, these modules will not function in other vehicles. The shared PCM ID is remembered even if the battery is disconnected. The instrument cluster also stores the vehicle's key identification code even if the battery is disconnected. There are special diagnostic procedures outlined in this workshop manual that may be carried out if either a new instrument cluster or PCM needs to be installed.
All elements of PATS must be functional before the engine is allowed to start. If any of the components are not working correctly, the vehicle will not start.
PATS uses a visual theft indicator. This indicator will prove out for three seconds when the ignition switch is turned to RUN or START under normal operation. If there is a PATS problem, this indicator will either flash rapidly or glow steadily (for more than three seconds) when the ignition switch is turned to RUN or START. PATS also "blips" the theft indicator every two seconds at ignition OFF to act as a visual theft deterrent.
The PATS is not compatible with aftermarket remote start systems, which allow the vehicle to be started from outside the vehicle. These systems may reduce the vehicle security level, and also may cause no-start issues. Remote start systems must be removed before investigation of PATS-related no-start issues.

99 Cutlass hard to start, when started runs for @5 seconds and stalls


This is one off the symptoms of a failed antitheft system which is extremely common on GM vehicles. Go to this link for info. Compare symptoms. Look for a light on the dash that says "security". If you see that light, then it's 100% an antitheft security issue. http://vatspasslockpasskeysecurityhelp.yolasite.com/

My 2003 cadillac escalade ext stalled yesterday & wont start. If it does start up it just runs for a second & shuts off. It has power & is deffinately not the battery. It turns over & seems...


This sounds to me like the antitheft security system. If the computer doesn't read the transponder frequency coming from the key, it goes into anti theft and shuts down the starter and/or the injectors. If it starts for 1 to 5 seconds and then shuts down, its probably this. Read up about this on this link, it gives you symptoms and causes, plus a "do it yourself" solution if you decide that this is the problem. I've been dealing in GM vats-passlock-passkey securities for quite a while now. From your description, I'd guess this is the issue. http://vatspasslockpasskeysecurityhelp.yolasite.com/

My truck use to start first click went to start it the other day runs for a few seconds then shuts down security code seems to be locked need to know how to bipass


Your Passlock may need to relearn the ignition keys, if the ignition lock has gone bad like my in-laws Grand Am Gt, here is what i did so they will not get stranded any more. Buy a Passlock by pass module for around $70.00. You can order one from GMPASSLOCK.COM in the mean time try resetting the Passlock. Good luck

Ignition keys relearn takes about 30 min to do. 30-Minute Learn Procedure
1.) Turn ON the ignition, with the engine OFF.
2.) Attempt to start the engine, then release the key to ON; the vehicle will not start.
3.) Observe the SECURITY tell tale light. After approximately 10 minutes, the light will turn OFF.
4.) Turn OFF the ignition switch, and wait 5 seconds.
5.) Repeat steps 1 through 4 - two more times - for a total of 3 cycles of 10 minutes. 3x10 = 30 minutes.
The vehicle is now ready to relearn the Passlock Sensor Data Code and/or passwords on the next ignition switch turn from OFF to CRANK Important: Turn the Ignition Switch OFF. The vehicle learns the Passlock Sensor Data Code and/or password on the next ignition switch transition from OFF to CRANK. You must turn the ignition OFF before attempting to start the vehicle.
6.) Start the engine. The vehicle has now learned the Passlock Sensor Data Code and/or password.
7.) With a scan tool, clear any DTCs if needed. History DTCs will self clear after 100 ignition cycles.

Without a scan tool you may have momentary starter interruptions while history clears itself.
