Gentlemen, Hae recently inherited 84 240dl B23f automatic. Other fella couldnn't get it running and gave up. I went through steps you folks have suggested in some of your posts. Jumped 5-7 fuses got dead fuel pumps to do their thing-no run. Check wires ad-infitum -no run. Changed both relays(System and fuel pump) on R side kickboard. no run. Changed ecu plus system relay, and Joila. She ran..That is the good news. Started it up next day smell burning from R side under dash we think. Here is bad news..the Ecu is very warm, almost hot and has burned resistor-like stink. Oh,oh. Turned her off. Subsequently discovered hot battery cables at battery connect (good battery) (oops, forgot to mention that the first battery had drained dead with nothing left turned on overnight. Must be something shorting somewhere.) Second battery is good, as stated. Then I felt the coil. OUCH! It was very hot. Methinks that tain't cricket. Should coil get too hot to hold? Could this be burning out the ECUs? What else should I look at possibilities burning out expensive ECU? OK, Sherlocks...lead the way. Dillon
