So I bought this Jag off a friend for 1000 after it randomly would not start. Its well kept with service records up to 120k (148k at the moment). I checked the inertia switch under the dash on the driver side, and nice a light scent of unburned gas coming from the exhaust while it cranks. However after checking for spark at the plug, I noticed the throttle body seems to be unresponsive. When cranking and pushing the gas pedal the butterfly flap does not move. another small thing I noticed was a melted diode that is not mentioned in the manual in the engine bay fuse box. I tried spraying starter fluid into the port on the side of the intake manifold while cranking and not even a pop anywhere. There was no pressure in the fuel rail that connects to the injectors. I'm not sure exactly what else to do from here since I could not find a fuse for the throttle body in the manual. I may start poking around with a volt meter to see if power is getting to the throttle body. Am I the only person to have this issue with an S type because I can't find much on issues similar to this. I'm no expert with cars to start with but this is the first time dealing with a Jag.

Ok so upon further inspection the diode for the fuel pump is pretty toasted so I ordered that and will let you guys know what happens next. Since I have had other shops look at this Jag I am not too optimistic in thinking they over looked something so simple but I'm eager to see what happens.
