Electrical problem
1992 Jaguar XJS 6 cyl Two Wheel Drive Automatic

Hello.
My Jaguar XJS Facelift will not start.
It was being a bit temperamental for a while, i stripped and cleaned the rotor arm and Distribution cap. Cleaned up the ignition amplifier and alu mounting plate.
It then started perfectly for a while.

Now it refuses to start at all. The engine turns. The fuel pump runs but there is no spark.

Help ... please :)

The Marelli ignition system is a fully digital microprocessor-controlled system. System components consist of the ECU, distributor, 2 ignition coils, 2 amplifier units, TDC sensor, flywheel sensor, air sensor, coolant sensors and idle switch. The microprocessor, located within the ECU, contains basic ignition timing requirements for the engine.

check TDC and flywheel (crank) sesnors
