I want to install a anti theft switch I have a 2003 wrangler standard trans I have a couple of options off the fuel pump or the clutch switch which would be better?

On my '97 Camaro, the first thing I hear when turning the ignition key is the fuel pump run and the fuel rail pressure up. .
First thought is, manual cars must have clutch depressed and auto cars in Park or Neutral to enable cranking. If these inhibit switches are faulty then that could be your problem. Had an old 5-speed manula Pontiac Fiero with a faulty inhibit switch. I just bypassed the switch with a piece of jumper wire. Just had to remember to ensure car was in neutral when starting!!
Do you have a shop manual with wiring diagrams? The Haynes manual schematic covering both Camaro and Firebird diagram shows a theft deterrent relay between the starter key switch and the main starter solenoid mounted on the starter motor. This relay actuating coil has a volts feed on one side of the coil from the inhibit switches fitted to ensure the car is in Park or Neutral for Automatics or the clutch must be depressed for manual cars. The other side ot this relay coil is grounded via the Theft Deterrent Module.
There is also a further fuse. Number 16, a 3 amp fuse labelled "Crank fuse" that is labelled as going to the Diagnostic Energy Reserve Module. Not sure what that is but with the fuse labelled "crank fuse" it sounds important!! it may be linked to the theft deterrent module but my manual is not clear on that.
If all the fuses are OK then I think the problem lies in the anti theft system.
To bypass the anti-theft and enable cranking you could simply break the yellow/black wire from the theft deterrent relay and ground the relay coil. (cut the wire and connect to ground / chassis, the bit going to the relay not going toward the anti-theft module) Turning the starter key should then apply volts that are coming from the transmission inhibit or clutch inhibt switches to the coil of the theft inhibit relay. This relay then pulls in and applies vots to the main starter solenoid and so enable cranking. The starter solenoid should be heard as a solid thunk as it pulls in. Small relays as a tick.
If this works then wire in a hidden switch in this ground wire to act as a unique anti theft device.
However if the vehicle control electronics are also fried then you will still have problems.
Hope all this is of some help and best of luck.

Anti-theft system has nothing to do with it . Battery cables , maybe , Park neutral safety switch possibly ! With anti-theft system problem you wouldn't a click or anything , that is if the anti-theft disables fuel or the starter . Plus the SECURITY light would be on if it were a anti-theft system problem . Your best bet , take it to a qualified repair shop that knows how to do starter circuit testing >

And what's this identity anti theft system ? No such thing ! The vehicle has a content theft an vehicle theft deterrent system !
This system disables fuel not cranking of the engine. The VCM/PCM will not disable the fuel due to any BCM message for the remainder of the ignition cycle.
If the VCM/PCM does not receive the same password from the BCM as the last learned one, the vehicle will start and then stalls due to the Fuel Lockout.

The security system would not affect the pump.
The anti-theft pass-key system disables the starter and the injectors.
If the pump has no voltage check the pump relay.

You are correct twice. The antitheft is failing and turning off the fuel injectors. Go to this link for help. This is a classic GM problem and totally 100% related to the antitheft.

The circuit you hear powering up for two - five seconds should be the fuel pump priming the fuel system . What type transmission ? manual or automatic ? Do you know what a wiring diagram is an how to read it ? Free wiring diagram's here http://www.bbbind.com/free_tsb.html Enter vehicle info. Year , make , model and engine size. Under system click on engine then under subsystem click on starting .Click the search button then the blue link . If you look at this diagram you will see the fuse at the top of the page that powers the ignition switch . You will see the ignition switch , the starter relay and the PCM - engine computer ! The PCM supply's a ground to energize the starter relay . But only if it see's that the transmission is in park or neutral ( automatic trans ) Or the clutch switch is closed ( manual trans ) .To see this you would need to go to transmission controls under transmission/transaxel . Plus the PCM will not energize the relay if there is a anti-theft system problem . You could do testing right at the relay base (where the relay plug's into ) With a test light ,voltmeter etc... Watch this video on relays

There are anti-theft devices installed in the fuel filler pipes, so you cannot put a pipe in there to extract any fuel. Depending on the design and location of the fuel pump, you may be able to **** fuel out of the fuel feed pipe to the engine. Otherwise you will have to remove one of the rubber couplings between the fuel tank and the filler pipe and insert a pipe in there. None of these places are readily accessible, so expect a bit of a tough job.

ANTI-THEFT SYSTEM Passive anti-theft system
Your ignition key has a unique imbedded transponder which engages engine electronics and allows the vehicle to be started. Without the use of your special ignition key, the vehicle will not start.

During each vehicle start, the coded key is read by the anti-theft system. If the key’s ID code matches the code in the anti-theft system, the vehicle is enabled to start.

Anti-theft system
Briefly illuminates when the ignition is turned to the ON position to verify that the passive anti-theft system is operating properly.

Also, its possisble that tou have actovated the fuel pump switch.

CHeck it.

I just had this on my car too. Turn the key to "on" without starting the engine. Look at the display and see if the Anit-Theft light is blinking. If it is, you need to keep your key in the on position for about 15 minutes until the light stops blinking. Start the car when the light starts blinking.

If automatic....neutral safety switch or anti theft.
If manual trans....clutch safety switch or anti theft.

check the clutch pedal switch, do the lights come on the dash like its trying to start?
