EEC does not energize unless key turned to start

[crazypete]

ok, I read the posting " again, How to cure code 66 (maf below minimum voltage)"

and here are the results:

dk blue wire continuity: 1 get 1 ohm between the maf harness and the ecu harness

tan wire continuity: 1 get .5 ohms between the 2 harnesses

black is solid 0 ohms ground

all resistances between all of the 3 wires is infinite

red is 12 volts at key on

backprobing the blue wire while the engine is running , I get about 1.5 volts (analog voltmeter, so I can olny approximate)
