If you disconnected a sensor with the engine running, and the CEL (MIL) should come one and it will generate a fault code and store this in memmory.
Turn the ignition OFF, then connect the jumper, and then turn ON the ignition without starting the engine, and now the CEL (MIL) light should flash showing the codes stored in the ECU.
It is possible that the Spectra you have is OBDII and possibly in this case the flashing CEL does not work. This I am not sure on, so you need to check.
I do know that the flashing CEL works on OBI.
Quality and not quantity counts.
