Hi All:
Posting this for the benefit of others, and also to say 'Thanks' to an older post from 2011 I found, when searching for help!


Home for holidays with family -- I'm helping my dad with his 2002 X-Type 3.0 Sport Manual, which had a non-functioning fuel pump. Car was sitting in garage for over 1 year, and failed to start but would crank after a new battery was installed. I followed the troubleshooting steps (engine started after spraying ether into intake throttle body), but would not run without ether, plus no fuel pump sounds. This was after I first checked for fuel pressure at the schrader valve, on fuel line, by intake manifold. Next, I checked the fuel pump fuse, tested the fuel pump module connector, and saw momentary power (12 volts) when testing pins 10 (fp positive) and 3 (fp negative) with key placed in on position. Out of frustration, I searched for the fuel pump wiring colors at the under-rear-seat fuel pump, fuel level sender connector and found this thread!
Thank you again! After verifying the color codes for the fuel pump wiring (red fp positive), and (yellow - fp ground), I disconnected the fp module; also disconnected the fp connector and battery. Then I connected 12 volts from my VOM / tester, and heard the pump operate! After hearing the fuel pump operate, I kept the 12 volt power connected for 2 seconds, and saw fuel pressure at the schrader valve! About 60 psi! Curious, so I connected the battery, turned the key and the engine fired up!! Result! I reconnected the fuel pump module and all other electrical connections I had disconnected, and the engine started and ran normally. I was able to move and drive the car out of the garage!

My dad says he last started and drove it January of this year, so not quite 1 year. He did put fuel stabilizer when he filled it with premium petrol. Today the car seemed to drive normally. I asked him to start and drive it at least once-a-week, so we don't have this scary no-start issue again.

Thank you again, Jaguar Enthusiasts Forum and @waynefay !! You saved our Christmas / New Years holiday!

Josh.

 

I find it weird and a bit worrying, that a car sitting in an enclosed garage, away from the weather (well, except for temperature and humidity changes) and not driven, would still experience system failures. I guess these cars are made to be driven, and not stored away. Still have to wonder, what in the world, would cause the fuel pump to just freeze / stick and not operate when it was time to start. I guess age affects mechanicals and electronics, even if they are used.
