I'm having a weird issue where my ecu will stop outputing to the power transistor on pins 54 & 55 but its getting good signals from the cas and top dead sensors on pins 21 & 22. The ecu board over all looks good and the caps were replaced a couple years ago as a preventive measure. But if I clean the board around all the IC chips and drivers it will run again for a few days. So I would really like to know the location of the driver thats outputing the spark signal so I can concentrate on that single area and see if I can get this to stop happening without getting another ecu. Thanks for any help.
