The factory anti-theft should prevent the fuel pump from running, and the engine from cranking. You have fuel injectors by the way.

Please can anyone tell me where to find the pass lock on a 2001 xjr v8 supercharged jag. It will crank. After having work done on it but will not stay cranked. Had new battery installed, also.


Doesn't have pass lock anti-theft system .What's missing spark or fuel ? May have some other form of anti - theft system . Your best bet take it to a specialty shop that does Jags

96 olds lss turns over but something is robbing the power security light stays on


The security light is for anti-theft system ,when the light is on or flashing ,it think's the vehicle is being stolen . It will disable the fuel system ( fuel injectors ) so it won't start ! Does your key have a pellet on the side of the key ? Trying to find out which anti-theft system yours has . If it does have a little black pellet on the side of the part that goes into the ignition lock cylinder , That pellet is a resistor an when you fit into the the lock cylinder there are two contacts inside the lock that read the resistance . There is a module that then can say if it's the right resistance or not , allowing or not to let the fuel injectors fire. The problem with this anti-theft system the contacts and or the wires break ! This is the VAT'S - vehicle anti -theft system or they have pass lock - pass key 1 , 2 , 3 . On the vats system a by-pass can be done . On you tube there are videos showing how to do it .

How do you disconnect a factory alarm on a 96 Cadillac Eldorado


You can't just disconnect the anti-theft system ! . If the modules on the vehicle don't receive a coded response form the anti-theft system the vehicle will not work , no start ! This coded response is send on the class 2 serial data communication bus to the PCM - engine computer , if it doesn't see it the fuel system , fuel injectors won't be turned on ! an in some cases the engine won't even crank over !
I have read of a way to by pass the system ! If you google GM vats an pass key by pass , you will see how to do it . Don't know if this works or not ! Haven't tried it !

Common issue with is car is malfunctioning of the "anti-theft/security system". If your security system is ok>>>>> Check fuel pressure, if poor....check power to fuel pump, fuel pump relay, fuel pressure regulator, if ok...Check MAP/MAF sensor.

How do i eliminate the anti theft on my ford windstar 1999 ? because the battery goes down each two days .Also the ABS light goes on after 5 minutes the car star. Thanks


You can not eliminate vehicle systems very well
You would end up with a check light on,and not be able to pass inspection

The ABS light, is a separate issue. Get the code,then proceed to diagnose. Could be a Wheel Speed Sensor.

Anti-theft


if the vehicle starts then stops and the anti-theft light is flahing you may need to re-set the pass-key system to do this you will need to atempt to start the vehicle and when it stalls leave the key in that position and watch the anti-theft light. it should flash on and off for about 5 to 10 minutes. when it stops flahing turn the ignition to off then try to restart your vehicle
