How do I go about that? Is the ground driver circuit in ECM? I have already replaced ECM. Also forgot to mention on injector 1 both sides are hot possible wires touching in harness? One more thought should the purple and white wire coming from the distributor be pulsing ground or positive. Could the problem be in the dist itself maybe cracked magnet driving me crazy all help would be appreciated. Thanks

The ground driver is in the ECM-check the resistances of the ignition pick-up coil in the distributor
