ecm issues?
My 1993 G20 with 305 will stall periodically and i can't figure out why. I have spark and fuel delivery is good. If i do a tap test and trip the relay on the ECM it will fire right up again. Will run fine for a while then all of a sudden it will stall out again. Put a used ECM in it and seemed fine for a while then it happened again. Any suggestions??
