Jaguar Repair: xjs v12, resistor pack, true grounds

Question
hello. i have here a xjs have spark. have no fuel been injected but have fuel pressure.

Answer
Hi Ian,

The next step is to confirm that the ignition pulse signal is reaching the ECU and that the ECU is powered and all of the grounds are true grounds. Then confirm that the resistor pack is powered. If you don't have a wiring diagram of the injection system let me know and I will put one on my web site for you to copy. Up to 1987 there are three different diagrams so I need the VIN number to post which one you have.
