You really have to detach and displace the aircon compressor (you don't have to disconnect the hoses) to access the front 4 plugs, and also remove the throttle pedestal to access the rear plugs. Although you may be able to get the old plugs out without doing this, it's very difficult to get new ones in without cross-threading them. Chris, kwecars.com

The Jaguar V12 engine was in production from 1971 to 1997. The V12 was only Jaguar's second engine to go into production. It was followed up with the Jaguar AJ-V8.
In 1989, Jaguar produced approximately 1,800 units of the XJS V12 model. This was part of the final production run of the XJS series, which was in production from 1975 to 1996. The XJS V12 was known for its luxury features and performance, making it a notable model in the Jaguar lineup.
I wouldn't think anything at all is common about a Jaguar E-type v12... but I could be horribly mistaken.
No, the Jaguar V12 engine and the Aston Martin V12 engine are not the same, although they share a common lineage. The Jaguar V12, developed in the 1970s, was primarily used in models like the XJ12 and E-Type. The Aston Martin V12, on the other hand, has its roots in a different design and has been utilized in various Aston Martin models since the early 2000s. While both engines are V12 configurations, they have distinct specifications and engineering characteristics.
On a 1988 Jaguar XJS V12, the fuel pump relay is typically located in the driver's side footwell area, near the fuse box. You may need to remove a cover or panel to access it. It's advisable to consult the vehicle's service manual for specific details and diagrams to ensure accurate identification.
In a 1992 Jaguar XJS V12 5.3, the OBD diagnostic plug is located under the dashboard on the driver's side. It is typically found near the steering column, often requiring you to remove a cover panel for access. If you're having trouble locating it, shining a flashlight in the area can help reveal the connector.
The 1992 Jaguar XJS V12 does not have a dedicated "truck button." Instead, it features a traditional trunk release mechanism, typically accessed via a lever inside the car or by using the key in the trunk lock. If you're looking for a way to open the trunk remotely, you may need to check if the car is equipped with any aftermarket remote access systems.
About 280bhp (claimed). More like 250 in reality
Assuming a V12 (the six cylinder is obvious), you really have to detach and displace the aircon compressor (you don't have to disconnect the hoses) to access the front 4 plugs, and also remove the throttle pedestal to access the rear plugs. Although you may be able to get the old plugs out without doing this, it's very difficult to get new ones in without cross-threading them. Chris, kwecars.com
