MommasQuest Posted March 10, 2009 Report Share Posted March 10, 2009 Hey guys! Can anyone tell me how to test the ECU on this car? I have a 1989 Conquest. Thanks. Link to comment Share on other sites More sharing options...
Wolf87Conquest Posted March 10, 2009 Report Share Posted March 10, 2009 Testing an ECU can be tricky...but patience helps a lot. If you have a diagram listing which pin goes where...that will be a tremendous help. There might be one here at the site in the manual. On a sheet of paper...list the pins...then under that, list the reading you get to compare with specs. Might get lucky and have the diagram and specs under the ECU cover. Some will go to ground, so make sure you have a good clean and tight connection to the case for accurate readings. A good meter is a must. Good luck Link to comment Share on other sites More sharing options...
Shelby Posted March 12, 2009 Report Share Posted March 12, 2009 page 14-55 shows voltage readings at pin outs,, start with the beginging of chaptor 14 fuel and read to page 55 Link to comment Share on other sites More sharing options...
