Hi Richard.....I have a 98 XJ8 , and Ican not start it. It turns over but does not fire. I have 2 codes Pending. P1111 and P1643 ??

Mechanic's Assistant: Have you checked the battery, particularly the terminal connections? Are they corroded?

They look fine but have not had them off and cleaned.

Mechanic's Assistant: Are you fixing your XJ8 yourself? What have you tried so far?

Only recharged the battery and grabbed the 2 error codes . Yes I do as much as I can myself

Mechanic's Assistant: Anything else you want the mechanic to know before I connect you?

Yes.......both Sets of timing chains and Tensioners have been replaced about 3000 miles back....no issues until this
