My car is a 1990 civic ex sedan. I swapped a d16z6 head onto it and cranked it over with the stock ecu and dizzy, the car started. I decided that the stock dizzy looked ghetto so I wanted to do the obd1 conversion. I got a p28 ecu and wired the obd1 plug to use the z6 distributor. Now the car cranks and starts but dies right away. I checked and I have spark. The relay clicks and I hear the fuel pump prime but I did notice my injectors aren't firing. Any help??
