ECM won't kill the spark on that engine, distributor can function without ECM input. ECM just tells the ignition module where to put the timing. If you want to check, unplug the bypass under the dash on the passenger side, brown wire in a single connector, taped to the main harness. Disconnecting the bypass forces the module to control timing based on speed, this is also for setting base timing. If it has no spark with that disconnected, the ECM has nothing to do with it. Any other basics checked? Power to coil, power to injectors, injector pulse, fuel pump run on key on? No spark may just be a symptom of no power. Distributor pickups do fail, but they usually cause erratic running. Replace the whole distributor if you decide to throw the pickup at it, the magnet and pole piece on the shaft crack and cause all sorts of weird issues.
