Hello List, My car hasnt been running in about a month because my ECU went bad. I just got a new one today and now I have run into another problem. The fuel enrichment circuit unit is not buzzing when the car starts or when jumped. I even jumped it from the RPM relay and all I got was a click from the lambda relay but no buzzing.(I had a rubber band around the full throttle microswitch while doing this so it would operate.) I checked the connections on the relay and they are fine and I even rewired it back to the enrichment unit and still nothing. what could be the problem? any ideas? Thank You David #2496
