The fuel pump doesn't work . I checked:
- the main and fuel pump relay ok
- inertia switch ok
- fuel pump 3 pins connector : 5 volts on the blue wire (gauge) OK , O volt on the green one...
- fuel pump relay socket (blue one) : I have 12 volts on the pin 30 and 86 but nothing on the 87 pin even when i bridge 85 and 86 ??
- no voltage on the C40 fuse circuit on the main board (fuse is good)
- no voltage on the coil (+ battery and - coil pin) - condenser seems ok.

Don't know what to check after ... and what to replace battery (old one) , coil ...

Remind me, diesel or petrol? On the diesel, the in tank pump only runs when cranking or engine running or, on later models when the glow plugs are active.
