1990 xjs rouge no spark no fuel injector click

Hi purchased a 1990 xjs not running. Cranks but no start. No spark at coil wires. Fuel injectors no clicking, getting power to coils Marelli ignition. Car was running went out to start after sitting overnight no start since. Crank position sensors recently replaced with genuine Jaguar parts before the no start condition I find it hard to believe they would be bad. What else should I check for?

Primary inputs for starting are
- Front crank sensor (TDC sensor)
- Engine speed on the flywheel
- MAP sensor

A no spark condition it will be one or more of these. Check the connectors and check clearance on the crank sensors they must be less than 0.040" away from the reluctor wheel.
