This was recently discussed. The fuel pump and the injectors get the 12
volt form a contact on the fuel pump relay. The relay is controlled by the
ECU. The ECU needs to see ignition on, starter request or engine actually
turning. The last one comes from the hall sensor in the distributor.

Subject: where does power to the fuel pump come from?

my singlecab syncro died halfway across my yard with a
load of sand (for the kids sandbox). Upon
troubleshooting, the fuel pump (NEW 1000 miles ago) is
not turning on with the key. Hmmm, So i hot-wired the
fuel pump, and it still doesn't start, even thouhg the
pump now humms away (yes, 1/2 full tank of gas) Hmmm.
What could have died that would keep the pump from
pumping and let it run, at all. Ignition switch?
thanks
