2005 Jaguar xjr wont start

Asked by Feb 26, 2015 at 11:04 PM about the 2005 Jaguar XJR 4 Dr Supercharged Sedan

Question type: Maintenance & Repair

Car has been harder to start last couple of weeks, tonight, not even a click, hear a
"shhhh" sound like air leak for 1 second then right headlight flashes 15 times. Battery is
good, 11.8 volts at rest. Any ideas ?

Sounds like an electrical problem. Check alternator output, battery and cables. advise after you check these items.

Turns out, moisture got to the connector to control brain under the hood. After 2 months it cleared up.


Great, glad you found it
