Re: Just bought a doner tracker for $200... Questions.
You ought to be able to replace the Tracker torque converter with your Sammy flywheel - I've never done it, but I don't know why you couldn't do it. Also, the auto ecm should be OK. It's not supposed to start unless the tranny is in N or P, but my spare ecm is from an auto and it starts and runs just fine with either ecm. Someone on this board said a little while ago that you could use an auto ecm in a stick vehicle, but not vice versa. You'll need a speed sensor for your speedometer - maybe you can get the one out of the Tracker speedo. You'll also need a high pressure fuel pump. You can get good rotary pumps at any auto parts store. The capacity is not critical, as the pressure is regulated at the throttle body. I have read that you should put larger fuel return lines in, but my ride does OK with the small Sammy lines. Good Luck.
If you ever get your ecm diagnostics working, please let me know.
