So Got my power Fc D-Jetro installed on an UNCUT sr harnes Previously running my sr20det with stock ECU.

Car would not start. No power to ECU, No Fuel, No spark.

Turns out the EGI Relay is not turning on.

I grounded the Red/Black Wire on the engine harness side of the chassis harness connection, and power FC will fire up and car will run.

I have power @ the EGI relay. So I am guesing my issue is on the ground side of the circuit. Where does the wire ground? what gives the relay the signal to switch?

I have searched Many times of people having this issue with the PFC, and alot of people seem to run a seperate relay for the power fc, But this causes issues with saving maps, If I can get it all to work oem, I would much rather that.

Thanks!

Look up the wiring diagram for which ever SR20 you have. IIRC, there are 2 power wires on the harness that the PFC needs to have to work properly. The stock ECU only needs one of those 12v to work. I had the same issue with one of my SR, ended splicing the 12v source together and it worked on my last SR.
