    1990 Accord DX no spark update
    1990 Honda Accord DX cranks but no spark. Multiple codes from ECM (1,2,3,7,8,14), and flashing"S" light CEL is on and steady. Does not give error codes when pin is jumped. Tach was checked, ignition swith is okay Distributor is okay. K-test shows no voltage from ECM to MAP (right plug, white wire). Main relay checked and is okay. Seems like an ECM problem. Am I missing something?
