2 things, first of all teh distributor cap and rotor go bad causing the car to have spark but not fire, secondly you need to make sure that you are getting fuel to the engine bay, if not then it could be the fuel pump.

In regard to the other gentlemans question, starts but cuts out I would start with the same process and open your fuel flap and make sure there is no water around the filler area as it sounds like you could also have water in your gas. (there is a drain next to the filler neck and it gets clogged over time, then when it rains or you wash your wash, that area fills with water and seeps into the tank)

95 jag 4.0 no spark, but power to both coil wires , plugs are good

check the distributor cap and rotor button for shorts /cracks and cleanliness. If you have changed the HT leads then check the firing order . Check the HT lead from the coil to the distributor cap.

Xjs jaguar wont start but there is fuel and spark

It was sitting for nine years? Normal cars I would tell you that things are probably gummed up and need to be cleaned and replaced. the time and the frustration and have a professional tune this one up and get it running. I say this as a do it yourselfer. If you want to tackle this yourself just take your time and be methodical about everything you do. Not as forgiving of a vehicle.

Hi my jag xjr 4lrt wont start it has fuel supply it has a sprak it turns over but will not start any ideas ive been told it may be the imobiliser

It takes three things to make an engine run. Fuel, spark and air. If you have fuel and spark at the cylinder, there's no reason it should not start. One or the other is missing. The only way to tell if the fuel and spark are reaching the cylinder is to pull a spark plug. Try to start the engine then pull a plug. If you are getting fuel, the spark plug will be wet and smell of gasoline. If it's dry, no fuel is reaching the cylinder. Put the plug wire back on the spark plug and lay the plug down where you can observe it while cranking the starter. If you are getting spark, yo will see the voltage arc across the tip of the spark plug. Perform this test and find out which one is missing and then you can trace down the problem.

My jag wont start it wont take a jump either, two new batteries radio was coming on by itself but my husband took fuse out, what can be the problem, thanks

I am not sure about thsi but some Jags had the immobilizer system connected with the original radio as there was also a code sequence to put in, does the car start if the fuse is back?

I have a 1992 xj6 3.2 Auto, started fine yesterday morning drove it down the road and it cut out (I assumed it was the battery as this has been dodgy) tried jump starting it but no luck. Engine is turning...

Well fer a start ya can't jump start an automatic, only a manual. Now Jags are notorious for this kind of behaviour as they are pommy cars and we all know what the poms are like, so any way remove one or two spark plugs an git yer sel some Aerostart or similar an give it a good squirt down into the cylinder head, screw ya plugs back in, connect ya leads then kick her in the guts and vroooom yer of and runnin again..

Acceleration slow or choppy

A tune up is a good idea.. Also depends when the last tune up was..
And yes - spark plugs are included in a tune up..

Wont start

Its not the fuel pump, 1998 jags are well known for the nikasil curse. Remove the spark plugs, sguirt oil down each bore and replace plugs after a few turns she should fire up
