Question about 1998 Jaguar XJ8L

1 Answer

My XJ8L stalled on the road when I pulled over it started again

Found a Relay Part number LNA6706AA APA Relay? That the housing is damaged and corroded. Could this have something to do with this problem ? Plus I just had it in the Jag Dealership for a complete tune up new plugs, fuel filter and oil etc this last week ? it was almost like vapor lock but I live in Colorado and its not to hot right now Thank You Doug

    Hi ,

    Thank you for your response, what happened was I was driving and I had my foot on the accelerator and the it felt like I couldn't accelerate, so I pulled over. The car was still running, so I shut it off, then restarted it, then it ran fine. The next day, my top hose came off the engine side of the coolant housing and I guess the Jag Mechanic that worked on this a day before, states that they had a bad batch of thermostates, but now the housing was swollen and now I have carbon dioxide in the coolant, they are trying to say that there must have been something wrong before. The engine was fine, before the tune up. Do you think the head gaskets or worse ? As far as the throttle I thought the same and I put some silicone lube on the throttle assembly, seems to be working I'm not sure if I have two problems or one on this. Tell me about this recall I haven't heard about it Mine is a 1998 XJ8L .

Not sure about your problem... did the engine stall out while driving on highway? Were you able to restart after you pulled over? I and many others have had that problem. There was a recall from Jaguar involving the throttle body. Once replaced, I no long have that problem.

    Here is a link to a pdf about the engine cut out/throttle body recall.

    My car is a '98 XJ8L also. The problem appeared to be with a faulty throttle body and programming. You would be driving down the highway at 65mph and then loose all acceleration (quite scary when your in the middle of the interstate with traffic). I was able to pull over without getting hit. The car would stall out and then restart and proceed like nothing happened. Check your VIN # and see if it falls with in the list. Jaguar should repair that problem whether you're under warranty or not. I had my upper hose come off too. It was actually the plastic/carbon fitting that the hose connected to. It had deteriorated for some reason, and the hose get hot and slip off that fitting. I'm not a mechanic, but I do tinker with my cars. Hope this helps.

My plymouth, voyager turns off while I'm driving it down the road..

Just an Idea. When it dies next time check the relay temperatures, if you can. Once I had a fan relay which would over heat and the radiator fan would not work. After relay cooled down it would work(This usually happened when I was stuck in traffic). Could be a fuel pump relay. If relay is a lot hotter than the other relay could be bad relay. My thought is it will not cost you anything to try it. I think it may be something electrical over heating. 30 years ago my thought would have been the coil, when the coil started going bad it would heat up and the car would die till it cooled off.

How to change thermostat on 98 xj8l

3, 8mm bolts hold it to the t-state housing located at the end of the upper radiator hose to the engine. The new T-stat will include a new seal. (if you notice a white milky substance on the old
t-stat you have a problem which may include needing a new water pump, by I digress) Do not put any silicone on the housing or seal.

after replacement, be sure all the air is out of the system, it will need to be "burped" and topped up serveral times before you go on a long road test. Be sure to use a 50/50 mix of Jaguar anti freeze and water to fill the system.

good luck!

Hey jkcalli!
Have you checked for any error codes?
Since your car is an 850 you should check your fuel pump relay, which is infamous for causing intermittent starting problems. Open the hood and remove the fuse box cover (4 torx screws), revealing the relays. If one of them is a green one marked 103 you should replace it with the newer, improved red relay. A used relay is cheap and should do just fine. 

Also, you should be able to hear the fuel pump working when turning the ignition to on. After doing this a couple of times the pressure becomes high enough for the pump not to engage. If so wait for the pressure to drop before listening for it again. 
Here's a topic with some info on the relay and how to check the voltage at the pump: 

If fuel delivery is not the problem you should check for spark. If you do not have spark the problem is likely coil, camshaft position sensor or crankshaft position sensor.
Good luck!

Stalling truck

Sounds like it could be a number of things Coil breaking down,ignition module breaking down or a failing relay.Could be ignition relay or fuel pump relay.The relay is the quickest,easiest and cheapest option to try first.
