Try over riding the relay switching and see if the pumps run .Check both pumps are running or not as would be very unusual for them both to fail at the same time

Pins 1 (small brown wire) and pin 2 (small yellow) provide the switching signal to close the circuit between pin 3(large red) and pin 5(large brown)
What relay is missing on my car and what is its function?

Be very careful if you try this ...... you have seen the size of the Red and Brown cables that feed the pump when energised ...... if you just link them and a pump is faulty with a short, then the wiring is at risk of overheating and catching fire .... remember there is no fuse in the pump circuit.
If you want to try this, just touch it on, and listen .... if the pumps do not start immediately ...... disconnect and inspect pumps.
BTW, the pumps are wired in parallel so will start and stop together ...... even when priming, both pumps run.
