Well after many hours of painstiking checks. I end up replacing the ecm, the sidekick ran for about 2 hrs than died again, same symptomes etc. I finally figured out the problem is the fuel pump which is intermintent. Sometime it works sometime it s not.
I have ordered a new fuel pump and still waiting to install it. In the interim I purchased some info to bypass the positive side of the ECM which should allow the fuel pump to work regardless of the ECM state. I have implement the bypass, which basically consist of tapping a wire between the ignition coil
black with brown spot wire to the red wire of the connector located in front of the carb, the plug in that goes to the injector. If you unplug this connector turn the key on *without cranking* and check for 12vlt with a test light on the red wire at the connector. If you got no power then the ECM is at fault other wise the problem lies somewhere else. So now I am waiting for the new fuel pump to see the end result of all this work.
