Question about 2001 Jaguar Vanden Plas

Engine won't start on Jaguar XJ8 Vandenplas TRAC NOT AVAILABLE

My car is a 2001 XJ8 Jaguar Vandenplas. Engine will not start and error condition TRAC NOT AVAILABLE is flashing on screen.This happened two months ago and the car started a bit later that day and worked fine since, until this morning. Would disconecting the battery reset the computer in case of a probe misread? Apparently, the TRAC NOT AVAILABLE is an error condition that prevents starting the car. Any thoughts?Thanks!

PS: Start is cranking and battery voltage reads 12.41 volts. And yes, there is half a tank of gas...

Hey blackdiam522,
First did you have a check engine light, and do you know what the code was if you did?

Ok, the traction control not available isnt goin to affect the car from starting.During my year of a jaguar tech the most common for a crank, no start is a flooded engine. Now the two most causes for a flooded engine on these jags are 1. the weather is just super cold and all the own does is keep cranking the car to try to get to start. 2. A lot of short trip, a lot of city driving, 15 mins or less.

When you get something like this, a no start crank, you have to pump the gas pedal really fast, like your starting an oil muscle car. this forces more air into the engine.

when this no start happend u could get all these codes, what i maybe would recommend is a tune up, and some highway driving every once and a while to kept this from happening again, hopefully this helps, thanks.

    I also have a 2001 Vanden Plas. About 10 days ago, I was in minor flooding conditions, and after going thru deep water (5-6 inches) the ASC NOT AVAILABLE and TRAC NOT AVAILABLE both were on. I didn't notice any change in the performance, and was able to drive home without incident, with the indicators on. Once home I cut the car off, then restarted, and the indicators were off. OVer the last 10 days, the two indicators have occasionally come on plus the ABS indicator, but again with no noticeable change in performance, and resets when the car is turned off. Today, I drove the car about 5 miles and stopped for 15 minutes. When I tried to start it, I only get a loud click, and the starter doesn't turn. All three of the indicators mentioned above are on, plus the check engine light is on for the first time. When I turn the switch off, then try to start it, I get the same click. The car is now stuck in a parking lot, so I don't know anything about the codes that may be set. Any ideas if this is an electrical problem or a transmission problem. Could a water flooded alternator cause the transmission indicators or the ABS indicator, possibly from a lack of proper electrical system?

Car doesnt want to start after starting few minutes ago

Right discoinnect the battery then leave for half hour ,join the battery leads together with a bit of electrical wire ,then try again ,i have found that these later cars suffer from interference caused by a mobile phone lleft in the centre consul ,why i have no idea but it be something by the wiring being or having a bus line where a communial signal is sent down a wire to recievers on each unit which are activated by the frequency modulated signal ,If you can understand this jargon ,i have a earlier 94 XJ6 4litre and never have a problem but then its my sunday car as the price of petrol here in spain is not cheap

42 miles with a jaguar. First I love Jaguars. Youll get to your home by a tow truck. The car is talking to you say its sick.Here is what will happen, The TRAC, ASC, light is on okay the APP will now go to limp home mode what this mean it will default giving limited operations, youll probable just go 30mph, and that is just it. The transmission does not know what gear or how fast its going so it communicates to the powertrain it tell it I dont know what Im doing so it activates the traction control and say keep me safe the traction control say okay Ill get disable, then the transmission control tell the powertrain I could be burning up or slipping. So The APP(acclerator pedal position ) gets involved and say we will just limp on home.Remeber i love juguars so does tow trucks

I had the same issue with my 2001 XJ8 and ended up having to have the car rewired from the engine to the battery. I was charged about $300 from a independent automotive electrician. Unfortunately this was after having a new starter and alternator installed! I was told that there were 2 or 3 service bulletins on this issue from Jaguar.

Good luck on this one, it's very frustating and had my car in the shop for about 3 weeks trying to figure this one out.
