Hi, I've got a '98 XJ8 and it has been sitting for sometime. I just replaced all spark plugs. I'm now getting codes P1000 / P1643, both pending. Car will not start. I did add a fuel stabilizer bout a month ago, and when I was doing plugs I noticed the throttle body had cruddy gas laying in the bottom. Anyone have ideas as to what I should do with codes?

 

Sorry for jumping in so quickly... I live near Kansas City, mo. I have a '98 XJ8 apprx. 68,000 miles. I've been visiting this site for sometime now, but just registered

 

Hi 98jagxj8 your code P1000 is Engine Control Module internal error and code P1643 is Fuel Pump Motor circuit low input. I hope this helps you.

 

This link to your codes should help http://www.jagrepair.com/images/Auto...%201997-99.pdf As for the P1000 that is an on board system check so for now just ignore it. The P1643 is a when an ECM fault is detected and limits the throttle to restricted performance.

I am thinking that you have been trying to start this car and caused the battery to go well below normal and that will cause many faults so for now I would say let it go for the moment. Your car is equipped with a Nikasil engine and that will cause a no start situation due to the lack of compression. This link: JagRepair.com - Jaguar Repair Information Resource will help you with a no start situation and near the end of it you will find information related to Nikasil .

If when attempting to start your car and the engine is spinning like it has no compression then you have a cylinder washing issue and the procedure will help.
