Your injector test brings to mind a couple of simple procedures that can isolate a no start problem quickly and without getting too dirty. Takes a couple of minutes, and a test light.
1. Check the fuses. Swap out the appropriate ones and try to start.
2. Check for ground break at the coil. Ground off the light, then, with the key on, probe with the light for power on the ground side of the coil, pole #1 on the Bosch. The light should light. Then have someone crank the engine for a few seconds. The light should blink consistently. If it does, you've most likely eliminated half the ignition system from the mix - including the ICU, the crank sensor and the power stage. No blink, and you do't have to futz around with the cap and rotor and wires, at least not until you've fixed the downstream problem.
3. Check for power at an injector, as you suggest. If no power, replace the RSR.
If everything works to that point, then move on to test for fuel delivery or lack thereof. Spray some starter fluid into a vacuum port on the throttle body and crank it over - a couple of firings from the engine burning off the susbtitute fuel tells me that fuel delivery is the issue. If I can't get even a cough, then I move to the distributor to check for spark.
And I always repack the muffler bearings during months with a "R" :)
