Scott in Bellingham Posted November 29, 2005 Share Posted November 29, 2005 I have a 87 ea82 SPFI 5sp dual range car tag 12/86 the computer I think gave out, the red LED doesnt come on , I have no spark , the car was running fine then just gave out, now I was wondering which computers will work out of which cars, I have a good comp from a 91 Loyale , it gives off flashing codes but still no spark, I noticed bunch of numbers on the ECM which ones are important and what exchanges with what? the original ECM has a big "N" on it also 22611 AA200 MECF-011 , 6Y24 3E thank you Scott Link to comment Share on other sites More sharing options...
Cougar Posted November 29, 2005 Share Posted November 29, 2005 Before you say the ECM is bad have you checked for power getting to it? On pin 18, a lite grn/yel wire should have power on it with the ignition on, and pin 49, a r/blu wire should have power also. The units can go bad but I think most of the time it is other problems.
