Having problems with your 1994 Jaguar XJ6 ?

My 1994 Jaguar XJS (V6) will not start. When I turn the key everything lights up, battery is tested and good, but not a sound from the engine. Is there a sensor somehwere that makes the car "think" I am in gear and not in "Park." Also, I want to rplace the ignition module but do not know where it is. Is it under the dash? Lastly, is there a fuse that may be the problem? Randall

Answers :

1. Yes, two sensors are provided for engine starting authorization: The first one is placed on the automatic gearbox shift selector electronic module, which send a signal to the ignition switch barrel only if the shift knob is placed in park - "P" position, or in neutral - "N" position. Only now you can take out the ignition key from the ignition switch barrel. The second one is the brake pedal switch placed above brake pedal in the pedals bracket, which send a signal to the ignition switch barrel only if the brake pedal is depressed. Only now it is possible to cranking the engine by the electrical starter motor.
\015\0122. The ignition module is called Engine Control Module (ECM), and it's placed under bonnet in the engine bay. I recommend you to access the ECM memory using suitable diagnostic equipment connected to the data link connector of the car in order to pull out all Diagnostic Trouble Codes (DTC). Then you will be full informed about the root cause of the problem, and you will be able to repair & replace bad pieces, and reset the ECM. Then you will can start the engine.
