FUEL PUMP??

1984 Jaguar XJ6

Engine Performance problem
1984 Jaguar XJ6 6 cyl Two Wheel Drive 98000 miles

XJ 6 started running rough, hesitation at times. It did stop running and has not started since. Fuel pump tests good. Has spark. We have got as far as finding that when you go to start the car, fuel pump comes on for a split second then shuts itself down. Causes? Thinking maybe the fuel pump relay or fuel pump diode unit is bad. Inertia switch also but not thinking so. Any and all help would be appreciated. Thanks.

Could be the thermo time switch, and or cold start injector?
