Where is the relay switch on s type jaguar. Car won't start even after a jump. Heard a clicking sound by relay box. Battery tested good.
I don't think a relay is your problem- but on a Jaguar, who knows? if you have a Jag, you should have a really good mechanic who becomes one of your best friends- bake him some cookies and treat him right- and DO NOT use jumper cables-
Do you have a second key? Try that if you do. If the immobilizer is activated that will create your symptoms. Could be many things but that is a quick thing to check.
