aulFlooded XK8 with no reason why!!!!

[paul72']

Hi, my father inlaw has a 2002 XK8 which he has serviced every year and never scrimps on cost - if it needs it it gets it. The car has just let him down this weekend without any warning and i wondered if anyone has any idea or if this is a common fault.

First off the car is used most days and runs fine without any problems and was switched off thursday eve after a run. Then on friday it would not start at all and after a few attempts he fetched our son from school in his van.

I had a look over it on saturday to find that the spark plugs were all wet so i checked all the coils for a spark which we had and the fuel pressure was ok too.
After leaving the sparks out and letting the cylinders air overnight we put the car back together and if a little hard to start the car was ok again!!!

Why would this happen? the car runs fine and has never missed a beat!!
Is there some part that will need to be changed to avoid this in the future?

Any help or advice greatley apprecieated

All the V8's flood very easily but normally its the driver that did it rather than a faukt on the car.

Examples, I moved the car off the drive to get the wifes car out and the next day it wouldnt start.

Or I moved it out of the garage washed it, when I went to put it back in the garage it wouldnt start.

That sort of thing.

If it doesnt start first try, full throttle and keep cranking should get it going with out having to take the plugs out.

Could be bore wash, best thing to do is remove the plugs, small squirt of oil in each hole, put it back together and should start straight away.


You should NEVER just run the engine for a short time

Another trick is to remove the fuel pump relay in the boot, turn the engine over a few times, then put the relay back in and try and start her up again.

The idea is to expel the excess fuel without dumping more into it.

That issue did not affect 2002 cars, and it had been for a run before it was parked.
I would want to retrieve any fault codes before proceeding. Suspect ignition or throttle issues.
