in the engine compartment......the passenger side inner fenderwall lifts out ( 2 tabs to release).....the ecm is right there, the rectangular box with all the wires coming out of it.

this is a good answer. if you have strut tower braces, you will have to remove the two bolts closest to the headlights and loosen the one closest to the strut so you can swing it out of the way. On the tabs mentioned above, they are clearly visible; carefully pry them up with your fingers (the side closest to the motor). You can see the ECM secured to the wheel well, remove the 4 nuts with a 10 mm socket. You should have a cover over the the four wire bundles that plug into the unit. Just slid it away from the direction the wires are coming from and it will come right off. Each of the four wire bundles have a locking tab on either side. Press these together and gently work the plug-in out of the unit (you may need to carefully use a flat screwdriver to pry the male end of the wire bundle away from the unit).

i have a 2001 Chevy lumina and i am wondering if the ECM is going out, sometimes it will die when i am driving but starts right back up, sometimes it will die and not start up after several hours of sitting, then it starts up. Could this be the ECM?
