The turbo RS relay feeds voltage to both the ignition Coil and the Fuel Injector ballast resistor pack. But it may not be working as fine as it looks.

I think it's possible to fabricate a jumper for the relay plug that will connect the thicker wires (red input, green output), simulating an energized RSR.

Or, my reading of the wiring diagram shows that a +12V jumper wire from battery + terminal to Coil #15 will substitute the RSR for testing purposes. The +12V at the Coil will feed back to the injector ballast, as though from the RSR.

Ether, aka Starting Fluid, should be found in any auto supply store.
