Time to dig out the wiring diagrams. On this car, The ignition switch closes on start/run to ground. This completes the circuit from the battery, through the Ignition Positive Relay coil, a diode, and the closed inertia switch.

The N.O. Ignition Positive Relay contacts then close, feeding battery power to fuse #3 (5amp), then to the Fuel Pump Relay coil, then on to the ECM output. The ECM output grounds the circuit ( to complete this circuit) in start/run.

The now energized Fuel Pump Relay closes its N.O. contact, connecting the battery to fuse #7 (20amp), then on to the fuel pump to run it.

So I guess I need to also check the Ignition Positive relay, as well as fuse #3 (5amp). I sure hope it isn't the ECM. Based on the fact that it has been in storage for several months, I'm betting it's the fuel pump has decided we have abandoned her, and has lost its will to live. My bad.

Film at eight.
