2000 XJ8 Stalling Problem
#1
![Default](/forum/images/icons/icon1.gif)
Hello, I am a new member of Jaguar Forums. I reside in Montreal, Canada. I am truly hoping one of the other members can help me with the problem or should I say problems I have been having with my 2000 Jaguar XJ8 recently.
I purchased my car about 2 years ago used. The body was in exceptional shape and the inside really clean. My Jaguar currently has about 110,000 miles on the odometer. Shortly after I purchased the car a problem developed where I would get in and try and start the car. I would turn the key and for a split second the tachometer would jump to about 500RPM and then return to 0 and I would get nothing, no sound whatsoever when trying to crank it.
The digital readout would cycle through all of the messages, ie: Gearbox Fault, ASC Not Available, Trac Not Available etc... and it would not start.
Often I would try it again and again and perhaps after 15 minutes or so it would just start like nothing was ever wrong. Also,I began having another issue around the same time with the non starting, I would be driving along and suddenly without warning the car would make a sudden bucking motion just once with a sound that sounded like a backfire and the car would just stall out.
I have always managed to get it going again from the side of the road but it definitely rattles ones nerves being stuck on the breakdown lanes on busy highways. I should mention I had started to notice a rather serious vibration coming from the engine at about 40MPH.
I thought after reading various postings on this site it might be the Crank Position Sensor. I changed the CPS and that did seem to cure the vibrations however, the stalling out issue which hasn't happened in a while returned yesterday with the car stalling out twice in the space of about 1000 meters.
I was accelerating to get onto the highway when suddenly the car sputtered and stalled out. I tried to start her again and at first got nothing, no noise like it was trying to start, nothing. Waited about 2 minutes and tried again, this time it sounded like it was going to start, it would crank but not catch.
I tried for about 7-8 seconds and stopped and waited about 10 seconds and tried again and this time the car caught and she started. I put it in Drive and began to accelerate to merge onto the highway as i was getting closer to the highway I gave it more gas to get up to Highway speed when the car did it again, it made a jerking/ bucking motion once and cut out. Again, did the same as above, first time it wouldn't catch, waited 10 seconds and it caught. I immediately exited the highway and took a secondary road home just in case the car acted up again but surprisingly at a lower speed on this secondary road without gasing the car too hard she was fine the rest of the way home.
My question is: I am thinking the Throttle Body could perhaps use a good cleaning? Is it necessary to change the TPS as well? I'm hoping that perhaps just a good cleaning of the Throttle Body and cleaning the contact pins on the TPS might do the trick. Anyhow, that is just my theory, perhaps other members might have had a similar experience. I would really appreciate any advice and a hand in the right direction to solving this extremely annoying problem.
Other than that the car when it is running runs great. Thanks

Hi Mike;
That's what my mechanic suspected too. He thought the fuel pump may be faulty. Did yours have intermitent problems before it finally failed? Also, would you recall how much it cost to change the pump? I think labour wise my mechanic said about 3-4 hours. Does that sound about right? Thanks
