This is not the case with a 22R-E. The pump does not run with the key, but rather it takes the engine to be sucking in air or the starter cranking to cause the pump to run. During cranking there is a bypass that turns on the pump with the starter and while running there is a switch in the AFM that keeps it going as long as air is being sucked in. There is no electrical switch on the fuel rail or anything, so it's sort of a secondary way to click the fuel pump relay. But it works. Grim's link to 4Crawler is good, Roger has lots of FSM pictures for a pre-1989 EFI system.
