Last week, my 2001 Jag xkr would not start and I had it towed to a local mechanic. Seems like the fuel pump quit, and upon disassembly, there were twin fuel pumps in the tank...We were both surprised. Anyway, pumps were replaced and the car runs. However, I noticed that I am getting a suspension fault when it is cold. After 10 minutes, I turn the key off and restart the car and the fault warning disappears. This problem seemed to appear since the change of the fuel pumps, and I wonder if something was disconnected or not reinstalled properly. Has anyone seen this type of problem???

 

The electrical connectors for the CATS Shock Absorbers are (I believe) inside the car in the area of the Fuel Tank. Maybe one of them became disconnected during the Fuel Pump Replacement.

 

The CATS control is in the spare tire well at the very rear of the car. That connector is pretty robust and if it is disconnected then there will never be a fault because the signal pin that indicates a fault would also be disconnected.

My guess would be one of the connections to the rear shocks. Those will be to the left and right of the fuel tank at the top of the shock mount. There are two wires that go to each shock to actuate the solenoid.
