Grrr....

Dealing with the same problem myself. This time on my dad's 93 Geo Prizm (Corolla).

Two wires per injector, both read 0v with ignition off and 12v with ignition on. (Injector unplugged)

I've tapped both leads now for the 'Guino and neither is putting up any numbers for raw data.

Guess I'll go make sure they have the same voltages with the injector plugged in.

Oh, and one more little tidbit. The injectors are ganged up, cylinders 1&3 and 2&4 so the ECU only grounds out one wire to fire two injectors. Dunno how that works with those cylinders being out of sync.
