I *think* that is true for the v6 engines. For the 2.6's, I think it only will run when you turn it to start. The system holds pressure (unlike the TBI systems) and in the 2.6, it won't run unless there is oil pressure and engine off, key on, should not give a signal to the pump to run. When the key is turned to start, it feeds battery voltage to the pump (system is already pressurized) and once the alt fires off, it then switches over to alt power.

Besides, the 2.6 fuel system is controlled by the fuel regulator, not the pump. If the pump turns on, it does not "know" when to turn off, excess fuel is just bypassed through the regulator. I suspect the TBI system may use the ECU to run the pump for a few seconds with the key in the on position.

Of course, this all started with I *think*.
