I had some issues with my daughters 98 RAV4 yesterday, still have them....in the process of troubleshooting a "no start" situation, I noticed that yesterday the Check Engine Light would come on if the ignition switch was in the "on" position. It now longer comes on and I thought that I read somewhere that was an indication of an issue perhaps with the ECM. Does anyone know of what that is? I've checked relays, fuses connections etc. still doesn't start.
