my xj8 wont start, put it in the gargen and never started it for 2 weeks!! all its doing is turning over, not a hint of starting tho?? only thing i can think of is its damp?(been raining here and frosty). Also noticed oil was really low! has it got a sensor that wont allow it to start if its low??
thanks for any help Adam

Adam, before you go to all that trouble, is the engine spinning over really fast, ie faster than normal?
Thats a sure sign you have flushed it out and lost compression, in which case the oil trick is the only option really.
If its turning over normally ie, a churning rather than a whizzing type sound, investigate other possibilities first.
Hope that helps.

Never noticed if its any faster? doesnt sound as though its got compression? is this a really common problem? must be that because when we got the car we were like kids with a new toy!!you know how it is
starting it,revving it then stoping it. its no been a good start eh.

Take the top covers off, 6 bolts, will need to take air intake off to access.
Unplug coils with small screwdriver in the clips, unbolt coils, remove plugs.
Just a 'glug' of oil in each, leave overnight. Spin the engine over with your foot hard down to cut the fuel supply and rags over the plug holes to push out the excess oil.
Reassemble, try starting with no throttle. Cross your fingers!
If it starts, let it run to go through its warm up cycle.
It will smoke like hell for quite a while so warn your neighbours!
Before you try all the above, might be worth doing a compression check on one bore, just to make sure its that and not an ignition issue.
Good luck.

If it is spinning over fast when you try to start - with a steady high pitched whirring sound rather than the usual slower whump whump whump then it's likley you have lost compression by washing the oil from the bore walls.
This is usually caused by starting and stopping the engine from cold - the engine overfuels and floods.
Take off the two black rectangular covers on the middle of the cam boxes. Carefully disconnect the leads on the coils and pull the coils off the plugs. Make sure there is nothing that can fall into the combustion chamber and gently undo the plugs.
Plugs may have been in the engine for several years and could be very stiff to initially loosen. Don't use force - if you can't get one out failrly easily, give up - snap a plug you're really f
ked.
Squirt up to a tea spoon of clean engine oil from a can into each combustion chamber. Check the plug gaps (should be 1.0mm) and carefully replace the plugs.
Re fit the coils and leads. Make sure you have a strong battery and try to start. Don't use lots of short bursts on the starter - keep the engine turning for up to 30 seconds at a time and modulate the throttle until you find a point where the engine speeds up and tries to fire.
Once it starts take it out for a drive and get it throughly warmed up.
If this proves flooding was the problem I'd change the oil ASAP to ensure there's been no fuel dilution of the oil.

Have'nt tryed that mate? its defo this other problem, i spoke to the old owner and the guy that got it going and its the same! really doing my head in now. This is our 4th jag and i've never heard of this before? but looked into it and it seems to be. The night i got the car i must've started it 5 times on the cold start!! which has took the oil out the bores
