This is really baffling me. Could use help. Pulled main relay and it bench tests fine. Had a crank sensor code, replaced with new. Timing covers off and all looks intact. Can see OBDII readout at port, but when I test probe connectors at ECU per FSM, I am not seeing power consistently at PIN 1 and 2 and there is no ground at 19.
Cleaned as many grounds as I could find. Have new battery. Amazingly, I can hear fuel pump run on key turn and the main relay energizes the proper five ports.
Have 12V to ignition control and coil pack, but no pulse.
Noid light will not come on at any time at injector 1.
Does this sound like failed ECU?
Thanks,
Matt
