Re: Fuel fail 89
THAT WOULD BE THE "PURGE CONTROL VALVE CIRCUIT". IT HAS TO DO WITH EMISSIONS. THE PURGE CONTROL VALVE ALLOWS VAPORS FROM THE FUEL TANK TO BE BURNED, BUT IN THIS CASE IT HAS MALFUNCTIONED. HOPE THIS HELPS. KEEP ME INFORMED. THANKS FOR USING FIX-YA AND THANK YOU IN ADVANCE FOR AN HONEST RATING. BEST OF LUCK.

Hi there: If you smell fuel there is a possibility that your car has a faulty fuel pressure regulator. When this part fails fuel flows through the vacuum line into the intake manifold and the presence of this fuel gives you the smell. There are other possibilities, but this is the most likely.
Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.
Fuel Fail 24 is the code for the Ignition Amplifier Module. These are very difficult to find for older Jags because Jaguar does not make them anymore. I also do not know of any aftermarket companies that make them new. I do know you can get a remanufactured one from www.jagbits.com. It will cost you somewhere around $300 but without it, the car is junk. If you need any information on replacing it, let me know, and I will be glad to walk you through it.
It could be an ignition related issue or fuel.
When it doesn't start does it crank, do you have the ignition lights?
The most common problem of intermittant no star probems is the crank sensor on the front of the engine, they can break down over a period of time and fail when warm. if not then I would fit a fuel pressure guage to the car and run it. Then see what the reading is when warm. If it is nothing (should be 38-40) then I would replace the fuel pump relay.
The fuel pumps typically don't fail intermittantly, they just fail!
Fuel pump is accessed through a hole below the back seat. Remove the seat and there is a rubber round cover over each fuel pump. Fuel pumps are held in place with a large round retaining ring that is screwed off.
