Check for 12vdc at the coils with KOEO. If they dont have power, check and repair the circuit. If they do, check the the other wire on the same coils (disconnected plug at the ECM and at the coils for resistance from end to end). If that tests good, swap 2 and 3 for 1 and 4. If there is no change, replace the ECM. If the problem DOES move with the coils, then replace the coils (assuming the plugs are ok)
