When I turn it over by hand, (with my test light hooked to the center coil
wire) and ground, is:
-fuel pump runs for a period of time, twice per revolution
-test light is on while the fuel pump is running, but only then
-I can't hear the injectors (maybe because I just can't HEAR them)

The test light on while fuel pump cycles seems wrong to me. Any suggestions?

Someone suggested that I check for a bad solder joint on the ignition driver
transistor. What is the ignition driver transistor? Is it inside the ECU?
Can/should I just go look (IE with my eyes) for bad solder joints all over
the ECU?
