from my 06 manual. Ignition switch position 0. Off.
press the rubber button on top
put ignition switch in position 2. Run. Pause a fw seconds. Back to off then try to start. The switch might say reset below the hole on the trim pane

 

I just googled" jaguar s type inertia switch reset" and there are a couple videos and other fuel troubleshooters. Check it out

 

I did some checking on the inertia switch, it doesn't appear to be tripped. there is/was no movement in the red button on top. The information says the red button should be flush with the top if tripped, mine wasn't. So I think I can rule out the inertia switch for now. I also checked the fuse in the trunk, it's good.

 

Did you work on the headlights

 

I polished the lenses.thats ir

 

Ok this was way out there but there is a crash sensor under the lip by the radiator and the wiring runs next to the passenger headlight...you did not disturb that. I found out it was there when i replaced my rad...did you look in the pdf manual for crank but no start

 

Although there can be number of reasons for cranking no start. On mine it was the fuel pump. The symptoms were that it would occassionally not want to start. I replaced the fuel filter but this did not fix it. After replacing the fuel pump I have had no problem starting. The suggestion above to check the pressure at the shraeder valve will give you the answer. The pressure from memory is around 45psi. Hopefully someone will post exact pressure. But I just replaced the fuel pump.

 

X200 fuel pressure specifications listed above.

 

Thank you all for the great and helpful advice. However none of it was any use. Let me explain. I'm an IDIOT. Any good mechanic or DIYer knows to check 3 things on a no start...Air, Fuel, and Spark. I had air, I hadn't gotten to spark testing and I thought I had fuel. Nope I had a running fuel pump but no pressure at the rail...you'll never guess why...no fuel in the tank...Doh!!! shoulda otta checked that first. Oh well lesson re-learned. In my feeble defence … no one suggesting to make sure I actually had fuel. Now it runs at least. Please feel free to razz me... I deserve it.

 

Look on the bright side. At least you don't have to fix anything..

 

love those easy fixes. Now you know the car heard you putting it under the bus. Maybe a detail job to make things square. I would have asked about gas but i guess too simple for my overthinking mind. You know step over a dollar to pick up a dime

 

Some people would have been offended if you asked a no brain question like "is there any gas in it?" Certainly not I. sometimes the easiest most obvious things are the solution. What is the saying...when you hear hoof beats think horses not zebras
