1999 XJR SC 4.0

Asked by Sep 07, 2019 at 01:59 PM about the 1999 Jaguar XJ-Series XJR Supercharged RWD

Question type: Maintenance & Repair

After replacing battery, engine turned over but would not start. No fuel pressure. Checked fuel pump relays, not getting enough ground to engage. checked all ground point in trunk and ECU ground. Is this a security problem? Immobilizer? My manual does not show location of immobilizer. Help! Would appreciate any thoughts.

check for spark~ then find out why we haven't got one~


does this Jaguar still have Positive Ground? the Lucas electricals would use that~

The engine will start if starter fluid is sprayed into the air intake, So it is not an electrical issue. The XJR has a negative ground. Thanks for you thoughts.
