Hey Zilvia,
I have recently purchased a 90 Pignose that had already had a SR20 Redtop swapped in. Although, it was missing the wiring. I ordered a replacement SR20 Main harness and it came with a KA lower harness, and went to work. Got all the wiring done and installed, went to crank it and find out it will crank, but not start. I checked and it seems to not be getting spark or fuel. I do know I wired the fuel pump correctly and can hear it prime. The car also has the battery relocated to the trunk, and although only has a wire to bring positive to the harness and the negative terminal to the body. I'm not sure if I have a grounding issue, but I do know that my ECU is not getting 12V to Pin 36(Ignition switch). I think this is causing the ECU to not send Pin 4 the information to turn on the ECCS relay and therefore isn't telling the ignition & EFI to work. I'm fresh out of ideas and need some insight
Just for more information, the car also has a N60 MAF and Z32 ignitor.
EDIT: found issue with wiring for ignition 12v, so now there's spark. And the PO had installed the fuel lines backwards so now there's fuel. Seems to be a timing issue now. Will fix the CAS tomorrow.
