Having a quick look at the wiring F22 is the pump fuse,

Which splits into 2,

one wire going through the impat shut off switch,

Presumably you have checked this for function?

then through relay K20 which is pulled down and activated by the ECU.

Grounding the black/violet temporarily should trigger the relay.

Try for battery voltage at white/violet wair from the relay,

this feeds the pumps,

Or you could inject 12V into this wire and listen/check for pump function

After this it's a suspect PCM or PCM ground fault.
