Tracker ECM fried
I was letting my '90 Tracker warm up a couple of days ago and it was doing it's usual surging until it gets warm. It suddenly quit. When I got into it to restart it I could smell a burned electrical smell. It would not start after that. I borrowed a shop manual from a friend at a Chevy dealer and went through the checks. I found the computer was bad. Just for the fun of it I pulled the top off the computer and found that the corner of it was chared black and a part was burned in half. All the circuts that plug into the ECM ohmed out when I checked them as per the manual.
My question is, Has anyone else had a similar thing happen to them. Could it be related to the surging problem when it gets cold? I dont want to put another ecm in it to have it blow up again.
Thanks in advance.
