I recently aquired a 1984 Jaguar XJS V12 HE that had been sitting in a barn for about ten years. I can find no rodent damage to the wiring harness. It has lots of fuel pressure and very good spark but it doesn't have any pulse going to the injectors. The harness going to the fuel injection ECU in the trunk looks good (no rodent damage). I am trying to find out how the ECU gets the signal to activate the injectors. Does it get the signal in the form of a pulse from the ignition amplifier on top of the engine? (GM ignition module in the box).
There is constant 12 volts to the injectors but no pulse.
If I can make this car run I will restore it as the body is worth restoring.
The car has 140,000 km on the odometer.
Any kind of advice would be greatly appreciated.
have the same problem?
