Could you hear the main pump whine?

To force the pumps to run, I find it easiest to jump fuse #5 to #7. When the fuel pump relay in my '82 quit, years ago, I jumped the fuses with a paper clip and drove 20 miles home. And then resoldered the relay.

"...not to remove all the injectors at the same time. What difference would this make?"

None, really, except that you're flooding the $*it outta the engine, and it all that gas washes past the rings and into the crankcase.

"...injectors be so dirty that they don't test but the car still runs?"

Nope. If the pumps deliver fuel pressure and you lift the plate, the injectors should inject.

One test you can try is to disconnect the return line (it runs adjacent to the fuel line near the filter) and direct it into acan. When the pump runs, the fuel should pour forth. Fifth, even.
