1991 LS with a B17 swap & a p61 ECU. Cant get distributor to work properly.

1992 Ls with a B17a1 swap with a P61 Ecu w/ jumper harness and a repinned obd1 TT44U distributor .

The aftermarket color code on the new distributor has different colors and I removed it from the connector before I could Mark the # order. I now am losing fuel pressure rapidly right after starting and then car shuts off. I can get the fuel pressure to stay on after jumping the main relay but the car still has a terrible idle. I’m now getting a code 15 and 9

Did you rewire the injectors for OBD1 and remove the resistor box?
