Hope someone can help me as i'm at my wits end!
2002 XJR 100 with full history and 82K - starts on the button when hot and cold BUT when the engine has been running for 20 mins or 4 hours stop and leave it for 30 mins and it takes 7 sec of cranking before it fires up.This fault is 100% consitent day in day out and makes no difference if the car has ben run for 5 mile or 500 miles.
So far i have changed the throttle body and purge valve. Very good Jag garage has run all computer tests on nothing has come up.
When its started its perfect - no oil use or blue smoke at any time

Turn the key on count to ten then start the car and see if it starts quicker.
