What is wrong with 1987 jaguar xj6 cranks no start no power to coil.could i have a problem with thief system if so how to by pass system?

Yes the best advice is to call Norms towing and for around $35.00 and change they will haul it away to cophers for you good luck T The factory alarm system is located on the passenger side, remove the panel under the glove box,there is a diagram on the panel. The alarm is located near the door lock ecu near the infrared reciever, if equiped. Look for a valet overide switch, also anything that will cut the power is tied into the ingnition switch + 12 volt white/pink 18 ga wire and the yellow acc wire.
