Keypad immobilser problem!

[kee616]

had this problem last night my car would not fire, breakdown company moved some wires about and the car fired up after a while. used it 3 times since fine and now its doing it again!
on saxos you can unplug the keypad once the engine is running to disable it, does this work on the C/S type keypads my car is a citroen zx 1.9 d turbo
many thanks!
any input would be great!!

extra: the keypad works fine red light then put the code in red off green on so its the stop solenoid on the pump i think which the immobilser controls

i am on the pug306 forum under the same name just so you know

i am 99% sure the answer to this is yes, failing that wire a permanent switched live to the stop solonoid, there is one going into the bosch glowplug relay, (if you ahve one) that can be used and will go off when you turn the ignition off

hi mate i had the breakdown company come out and no luck getting it to fire up this time
any suggestions on how to bypass a lucas keypad XUD? its an immobilser fault but where is the stop solenoid? the guy suggested the same thing running a live to it

Stop solinoid is on the fuel pump. Have you got bosch or lucas

the lucas pump has a really thick pain in the arse "security" shroud around the stop solonoid, , this has 3 wires going into it, 1 is a permanent live, the other 2 are controlled by the keypad, and they all need to be connected to the circuitry within the shroud to work properly (and turn on the solonoid).

this pump was designed with the inherent weakness in the bosch and other lucas pumps in mind (so you couldnt simply run a live to the stop solonoid and bypass the system)
