Ok, I have a 91vert that is totally stock (I think) and I am getting NO spark, I pulled the ECM out to look for obvious problems and want to make sure its even the right one. It says "N352" I think (it's pretty faded). It also has a sticker from "Auto ECM Electronics in Grand Prarie TX on it with a 'sold date' of 5/10/02 so I KNOW it has at LEAST been 'serviced' if not modded (is that possible?). Any way, my question is- is that the correct model ECM for my car? and does anyone know where I might get a known good loaner to test in my car to see if it is the problem??

all assistance and suggestions greatly appreciated!!
