I have a 2004 Rodeo which will not start. It turns over but will not fire. My mechanic has had it for weeks trying to figure out the issue. They have determined that it is not getting spark. They traced the issue back to the ECM and they are telling me they cannot find a rebuilt one and they can't just take one out of another car because of the VIN being imaged onto it. So basically I have a mechanically functioning car that can only be used as a paper weight. Anyone have this issue or know how to resolve? Much appreciated.
