I own a Jaguar xjexecutive ,1996 model....it refuses to start,after researching I discovered the 'body processor unit is bad'......I'm having difficulties searching for the right one with the number: LNA2500BB/002...i'm ready to make a purchase but I haven't found one....please if anyone has one or knows how I can get one here's my instagram handle :billy_turner1002

 

Welcome to the forums oghene ejiro,

Check ebay UK - there are a few LNA2500BB Body Processor Modules listed.

I recommend you add details of why you have concluded the BPM is at fault. Members with the same model may be able to suggest other possible reasons for the non start.

We need to know if it will not crank, or will not fire up and run. If no crank, then one of the simplest things to check is that the red "P" is lit up on the shift indicator. If not, the starter will not crank. Also try Neutral to see if it cranks.

 

Hellooooooo,my car won't start,won't crank,the red light indicator on my j shifter comes up,I have tried putting it on neutral same thing,all my lights and entertainment system works....I don't know what to do next,I saw a video of an x300 on youtube,that shows similar problem,the body processor unit was replaced,and the car was ok....but my xj body processor unit number is rare to find....i haven't seen any......'LNA2500BB/002'.....

 

Here's a couple of very simple tests you can do that will help eliminate some possible issues that can cause a No Crank.

1. Engine Ground. Use a jump lead to connect a good solid engine part to a good solid body earth point. If the car then cranks you know you have an issue with the earth strap (on engine down near starter motor)

2. Starter Relay. The starter Relay is in a group of 4 near the LH Headlamps. Swap the starter relay with one of the others (e.g. Fast Wiper Relay). The relays are identified in the Electrical Guides that can be download from the "How to Quick Links" section here

Also, check that the engine Management Light is on when you try to start the car.


If you have a multi meter and some basic electrical knowledge there are more tests that we can suggest to identify the cause of the problem before buying a new part.
