Just did a Y8 swap in my ef on a P28 ecu. Was going to calibrate the tps, but i realized i don’t have power. i checked the wire at the ecu and still no power. the ecu is getting 12v as it should. i’ve also tried using a P06 which i know works, same story. is there a fuse or relay that needs replaced? i’ve checked all standard fuses and all look okay. the harness is ground to thermostat. Thanks.

 

I fixed my problem. my main fuel relay was plugged in, and it was causing the voltage problem. everything is fixed
