Jaguar XKR X150 07 major misfiring issue
 

Hi guys,
This is my first time posting on this forum and I am admittedly somewhat ignorant of jaguars.
Despite my ignorance a little over a year ago I invested in an 07 XKR and up until recently it has served me very well and has been very well looked after.
​​​​​My problems began around two months ago when it developed a significant coolant leak from a reduction hose in the valley. It was diagnosed and repaired by a reputable Jag specialist and all was well. However a few days later it failed to start again after returning to it after a brief shopping trip, which as quickly diagnosed as a charging issue. After that the alternator was replaced.
Upon collection it immediately started to misfire and was returned to the garage (total journey was probably less than 300 meters). The garage say it will no longer start and have suggested that it may have jumped time because of a cam chain tensioner failure.
My question is, could there be another reason? It ran fine for around 100 miles after the coolant leak. I'm thinking a compression test is the first port of call.
Thanks in advance for anyone willing to help me.
