so the car will turn over and not start ive checked all relays and fuses and they are all good. i get the code P0688 ecm/pcm relay . i am not sure where to go next any help,thanks
also im getting no spark which im guessing is because of this but if i hold the contacts together on relay R4 i do, ive tried a new relay and nothing changes
does anyone know what number relay is the ecm/pcm and also does anyone know what pin on the ecu and the pin on the relay that i can check for continuity of the wires in case there is a break
In the MY(model year) they have two diagrams for fuse/ relays etc based on build date. Perhaps you can post up a picture of your SB fuse box next to the battery so I can see how the relays are install.
