x300 pump not pumping, instrument panel lights once

[Kay69]

 

Hello,

 

I recently bought a 1996 Daimler Six with 127,000 km on it. 

 

The car is in fairly good condition. The engine and transmission worked fine. 

 

However, I had it suspended on jack stands outside my house during the summer, tyres off, while working to change all four struts myself.

 

Few days ago, I lowered it, washed it, washed the engine, tried to start it but it did not. Even after a week or so. 

 

After going through several inspections and checks of fuses, relays and switches ,the current situation is this:

 

Instrument panel only works once then I have to unplug the negative battery terminal for a few seconds, put it back, then the instrument panel will light up again . If I turn the key off, panel lights won’t go back on until I unplug the battery for few seconds.

 

The engine cranks, but there’s no fuel delivery from the fuel pipe in the engine bay.

 

Noticed the fuel pump relay socket has some carbon marking on it (see picture). I’m not sure if this is old or recent.

 

I jumped the relay terminals with a paper clip to test the pump, but did not hear anything. 

 

The fuel sender unit leaks tiny fuel. I plan to replace it. 

 

I should mention the harness loom socket on top of the fuel tank is not in its best condition. 

 

It was glued before (when it bought it) and now I have a temporary fix which is not solid (I took it off, now I regret it)

 

I still need to insure the socket is totally pushed in every time I want to crank the car (indications: instrument panel lights ON, roof and doors corner red lights ON).

 

Inertia switch seems to work fine (it cuts off when pressed and held).

 

key FOB does not work. Central and boot buttons do not work via FOB, dash or, directly buttons.

 

Gear lever lights are on.

 

One auxiliary fan runs whenever I turn the key to access position ( I think this is normal).

 

Roof, windows, side mirrors, A/C fan all work.

 

Finally, There are two worn wires in the front tyres wells which I’m not sure what for. 

 

Sorry for the long writeup.

 

Appreciate your feedback.

 

Regards,
