Hello, I have an interesting issue. I have traced a no start to this 1g ECU not providing a ground to the MFI relay when the key is turned on. However when pin 63/66 is grounded on the ecu it'll start. The interesting thing is when I use a multimeter and turn the key on it shows continuity to ground through MPI relay pin #8 that goes to ecu pin 63 and 66 but it seems it cannot carry enough load to activate the MPI relay. I suspect a transistor or MOFSET is the issue, I have considered using a relay to ghost a ground to pin 8 but this seems a tad "lowbrow" to me. Is there someone here that's familiar with the ECU's architecture to help me repair this?
