UK Car Repair: jaguar xjs 1988 v12, jaguar xjs, inertia switch


Question
The fuel pump is not getting any power. The pump has been removed and tested ok

Answer
First check the inertia switch which is just in front of the door aperture about knee level - it could be on the right or left, you can reach it with your hand and push down on the reset button, it may have been activated. Next you have to go to the pump relays up in the Right inner corner of the boot behind the plastic cover. There are two of them, I think the large purple and white goes directly to the pump. Check that you have a feed to the relay -(large brown) the relay should divert this directly to the pump when the engine is cranked.
