Ok so i got a d16z6 head and put it on my a6 block and tranny in my 1990 crx si. I am using the stock ecu and harness but i did get a destributer for that head. I got everything hooked up and it will not start? I used the a6 intake because the map sensor needs to be vaccume not electric. But when i goto start it it fires up for a split second then stops. Its not fuel pump i checked it nd its fine i also checked the main relay and its fine. Does anybody know what cld b wrong????
