New here, automotive technology teacher looking for help on sr20 swap. Ka to sr20, red top. Two students doing a swap, my first go-round with this swap. All (or at least I think) mods, extensions to harness complete, no ground signal to ECCS relay or Fuel pump relay. 12v power good at both. ECU red light on, has constant 12v power and all grounds good. Pin 104 and 4 not sending ground to the two relays mentioned above. Has 12v on starter signal to ECU, cam sensor has pwr and ground, injector pulse(on #1)

Been through wiring several times, swapped ecu with another sr20 ecu, jumped ECCS relay with fused jumper still no fuel pump ground from ecu.


Not sure if all this is related or may be seperate problems. Anyone ever ran into anything like this???
