Jeep used to run and drive fine, starts will not run.
Wires on steering column cut as if to hot wire to steal, this now fixed. Will this have affected immobiliser thus stopping the fuel supply. If so where are the immobilisers so I can disconnect them?

Re: Starts will not run
I did not realize this happened so much! I am guessing there is the little amber "Security" light flashing, on the dash? Even if it is not, this is worth a try, it is free! My jeep did this, when the battery got really low, and I jumped it, and one time it did it when I opened the wrong front door first. Put the key in the driver side door and lock and unlock it at least 5 times, and try to start it. My wife left the park lights on in her jeep and it stayed at work for a week before a friend who worked at a dealership told me to try this. They do not often give this info out.

sound like loose wires to the ignition switch in the steering column. just remove steering column shroud and lower the steering column check the ignition switch wires.first disconnect negative battery cable before working on ignition switch. either switch wires loosen or switch could be bad.
I'd say so! THey probably tried to start it by pulling wires under the dashboard like on television. Check the wires coming out of the headlight switch to see if one or more isn't pulled off. Also check around the stearing post for the wire that connects the high beam/low beam switch. The heater is another problem. Is the heater fan working? If so the problem mis the thermostat control...check that it still opens/closes the valve on the hot water hose that goes into the dashboard core.
On a 2002 impala, the switch bypass will not work. The switch bypass originated on the VATS antitheft system which was the predecessor to the system your car has now. Your car has the Passlock system, this system runs off of transponder in your key. On the old Vats system you could read the ohms resistance of the chip in the key, and then recreate that same resistance in the steering column. Thus bypassing the ignition and key. Your system is more complicated. Think about it like this, if a criminal wanted to steal your car, he would rip off the steering column to hot write the ignition. But your car has that anti theft, so it wouldn't start. Wouldn't it be a little too convenient if the Antitheft wires were also right there and all he had to do was twist them together? They learned that lesson on the vats system. Check out this link for info and some "do it yourself" solutions to fix this problem yourself forever.
Its the PASSLOCK Security system that is the problem,its shutting down the fuel injectors so a would be burglar can't steal it.You can either replace the ignition key switch or get to the wires coming from the switch in steering column and cut the yellow wire and tape ends.This way the injectors can't be disabled.
The fix is unbelievably simple and NOT the ignition switch. It is however the pass lock white wire. The wire is located in the steering column. You can find a youtube video on it. You simply remove the airbag fuse (for safety), unscrew two screws under the steering wheel, you will see many wires. Find the wire wire (a guy has a complete instructional video on youtube), crank your Ion, cut the wire while it is cranked, seal the ends and replace everything. The only draw back is the passlock dashboard light will stay on. The passlock system is basically is someone steals your car without a key, it tells the computer to stop giving it gas. I had the same problem and since I cut the white wire it has cranked EVERY time. Good Luck, it will only cost you around 5 bucks...
you sure can bypass the security! i just had to do it on my 97 achieva and was amazed how simple it was!here are the steps to take:
1- if it has tilt steering, unscrew the handle for the tilt and remove from column. 2-remove the cover from the steering column. 3- on the passenger side of the column at the key switch you will see 3 small 20 gauge wires going from the ignition and up over the steering column.. 4- the wires are yellow, white and black. start the car and let run for a few seconds and while car is still running cut the yellow wire. turn the car off and try to start. will start every time! i done mine 6 mo. ago and never fails to start. i got this info from a top certified mechanic who's been in business 35 years. dont take it to GM because they will try to give you the run around and tell you it will cost 400 to 500 dollars to fix and some of them will even try to tell you it cant be disabled! lol the only drawback is that the security light will be on and maybe blink like mine does but when i think about 400 or 500 dollars, i dont even see that light! lol trust me. it works! have a good day and good luck!
Most likely the ignition switch is failing. The ignition switch has the sensor for the security system and when its cold it disrupts the contacts and causes the wrong "code" to be sent to satisfy the security system and allow the car to start. The switch itself is cheap, installing it can be tricky, but could be done by someone with a little effort.
