1996 XJ6 4.0L wont start. Fuel pump doesn't run,(replaced) lack of power, will run if relay (also replaced) is removed and points jumped still wont start, No spark to coils. Checked emergency cut off switch, okay. Checked cam speed sensor (replaced) NOTHING. Any advise is welcome as I don't know were else to look. Keeping in mind there isn't a Jaguar mechanic with in miles in. Thank
Mine was modified by the previous owner and the modification went bad because of the workmanship so I learned about the circuits so it would , so it would , so it would puuuur like a Jaguar . Hang on .
Do you feel a click on the king relay in the RH engine fuse box ? If so you can still swap relays in the LH fuse box that is used only for the horn .
Since you have no ignition check fuse # 12 / 10 amp RH fuse bow for coil power source .
Do you feel a click in the ECU controlled relay # R5 ? If so you can still swap relay with the A/C relay # L3 . This is the second source of ECU and sensors power after the first timed power to the ECU .
To complicate maters you may have put your engine in a bore wash condition where the unburned fuel may have washed the oil off the cylinder walls so you don't have the compression for a successful start , easy to resolve .
