The other ones
, The warning will stay on as you are sort of bypassing the “problem”.You need to look at the ETM to see what prerequisites are needed to trigger the pump. Probably the pressure switch? (Guess)
As said get your meter and the elec diagram
.Top of me head I don’t know, and don’t have access to ETM at this time.

Is that ref to 26 a typo? should it read 86? if so then I am guessing that you have power to the relay "switch side" . Your test 87 to 85 proves nothing.
You need to test 85 continuity to ground, as you can see it goes through a few connectors and the pressure switch to get to ground. So its a process of working your way along that line to find the break/****ty connection/ or faulty component.
Test for voltage on the correct meter setting then red probe the pin then black probe to earth do this again for 86(26) probably need ignition on to test. Should show battery voltage.
Testing for ground continuity with ignition off, you are testing the state of the line not the voltage.

good.
Leave the relay out.
now check pin 85 to earth.
Use the setting on the meter where it bleeps if you touch the 2 probes together.

Don't know if it's been advised earlier but does the fuse box smell of burning?

No the fuse box is fine only the relay smelled of burning I changed it but didn’t cure the issue

That probably means open circuit. try with the meter set to beep for continuity.

If you connect the probes together, the display should read zero, is that what you get?
If that is so, then when you connect from 85 to ground, it should also read zero.

It's likely that the connector for the relay is damaged if the relay smelt of burning
