i just finished swapping over the 1993 civic si motor onto my 1999 civic dx. i used the dx harness and extended a few wires... the problem is i cant seem to start the car and i cant hear the fuel pressure rise at all.. what is the problem here? the ecu that i am using for now is a 99 dohc si ecu... the motor doesn't make any noise when i try to start the car. any suggestions ? ????

 

check all your grounds... loosen the fuel filter a little see if there is air in the line if you think it is a fuel problem..

 

do u hear the relay clicking? search up relays and your fuel pump

 

Check the fuse box if all are good. Maybe some fuse blown while extending wires...

 

my guess is bad wiring, bad main relay, bad fuel pump. in that order

 

thanks guys imma go check all of the above and i will get back with the news
