hi guys can i rack some of your brains my father in law has the above car .

this problem has happened before to which he paid jag over 1k to fix it. they put it down to the ecu (£700 :shock: )

 

its now 4 months down the road and the dam thing wont start again..he needs the car to get to and from work so are there any common problems with these cars with regards to not starting as he cannot afford to put it back into jaguar this side of xmas :headvswal

 

thanks in advance

You could try to take up the ECU and make sure there are no corroded parts etc. My father had a similar problem with his Porsche and they tracked it down to the ECU, which leaked in water and caused it to corrode. He bought a new one which was very expensive by then, and the old one started to work after he tried cleaning it a couple of months later...

Dont know how old your dads car is mate, but i had a 2.9 jag and his symptoms ring a bell, i had problems for a couple of months with mine, it used to start when it pleased it would run perfectly for days, then it wouldnt start, i had it in 2 garages (not jag, i couldnt afford it) and they came up with different reasons which i tried to fix but all to no avail. Then 1 day it just refused to start, I run the battery flat trying, Phoned a friend of mine for a jump start, he came round late that night and we tried jumping it, it was only then when it was dark that the problem showed itself......the whole of the engine bay lit up like blackpool illuminations! the coil had broken down and was arcing everywhere, new coil at 12 quid and car run for next 2 years without a hesitation. Hope this helps, sometimes its the simple things that you miss

thanks guys

I had a problem with mine whereby it sometimes just wouldn't start, turns out that Jag cold start sensors don't work very well when its cold :mac1:

 

Cured the problem by disconnecting the cold start sensor and the car ran fine.
