My jaguar is 1995 XJR sovereign, initially it was starting but when driving it will just go off and you will have to wait for some minutes before it can start again. Later it didn't start again and I called a technician to check it and I was told it is the crank shaft sensor.I bought a new sensor and replaced the old one there but to my suRprise it is not even making any sound again when u try to start it. Right now that is the problem, it just won't start. Kindly assist with whatever you think the problem might be, thanks.
