Jaguar v12 1992
This is a very common fault with Jaguar V12 engines, they tend to cut out like clock work. These engines have a quite complicated engine management system with one ECU (electonic control unit) in the boot another ECU in the passenger footwell and two ignition amplifier ECU’s towards the front of the engine. So these systems can be very complicated and time consuming to diagnose but one very common fault is with the Crank Shaft Sensor located at the front under side of the engine, just behind the crank pulley. The sensor breaks down when it gets hot and cuts out the engine. This fault is quite common on most Jaguar engines.
