Hi Dan, You are communicating on a thread that has been out of use for over a year, and probably not relevant to your problem. You will get more response by opening a new thread.
There is a possibility that one of the exhaust cams has skipped a tooth due to a failing secondary tensioner. Your first move should be to remove the valve covers and determine if the camshafts are in alignment. Lots of information available in the DIY Sticky on the procedure. Attempting to start the engine without that information could cause major damage.
Members would like to know some details, such as year, model, miles so that they can assist you.
If your ECU is not responding it could be a blown fuse, but you reported a reading from the scanner, so that is unlikely. The best thing to do with results from a generic scanner is to report the actual code here. They often do not correctly interpret jaguar codes.
You can download manuals here for free, including JTIS21, the workshop manual.

Yes, I had a bad ECU! I found a matching used ECU on eBay and had AutoECU (i think that was the name of the company) transfer the information off my original ECU to the replacement used ECU from eBay, they also rebuilt the replacement ECU and gave me a lifetime warranty. Plugged it in and it worked perfectly! Cost me a total of about $600 I believe, sure beat the $6000 Jaguar quoted me for replacing it with a new ECU.
