Phwo this is a difficult one.
First the clicking mc solenoid sound is only hear-able when you want to read the codes NOT when you want to start the engine!
Are you sure the other ECM is a good one as the light stays on and you can not pull any codes?
With the ECM light on the ECM will stay in open loop so there should be no to little difference with a broken ECM I think.
Greetings Peter
Thanks Peter,
I've always been able to hear the "clicking" from the carburator with the key in the switch and the switch on, just before cranking the engine. Was that not normal?
I"m not sure if this new ECM is good or not, it was used and one a friend just let me try to see if anything changed. I will purchase a new rebuilt ECM if you guys think that is the next thing I should try.
UPDATE:
So, I pulled out my old OTC Monitor 2000 and hooked it up to see if I could get any trouble codes with it. As fate would have it, I did get three trouble codes...oh happy day!
Code 54, code 23 and code 41...now 54 and 23 are related to the M/C solenoid, but I can't find anything about a code 41in my shop manual, but those are the three numbers that kept flashing. In the OTC book it says...
Code 23 - M/C Circuit Solenoid Low
Code 54 - Shorted M/C Solenoid or Faulty ECM
Code 41 - There are two things listed for code 41, but neither apply to the 1981 model...one was No Distributor Ref. Signal and the other was Cam Sensor Failed...but in the chart the mode years listed are 1981 through 1984 and there are no "x" in the boxes in the 1981 column. So that makes me think this code would not apply to my car.
