I have a 90 Honda Civic STD, I recently swapped my obdo dpfi to an obdo mpfi, I followed all the instructions I copied off others who have successfully done swap but now I have no power to ecu (no light coming on when I turn key to on position and no fuel pump or spark at plugs). I have checked and replaced all fuses.
someone please help before I burn this car to the ground

 

Checked ground strap/terminal issues? It always seems like the simple **** happens to me. Turn running lights on and fool around with the cables, see if they flash at all.

 

injectors, coil, ecu, and fuel pump are all powered by the main relay. check the main relay, and all wiring related to the main relay

 

ok so it has been a long process of conversion but she is running Nice, however now my AC is not working and this is something I am interested in having for these 104 degree days. Does anyone have any idea how to get AC working again after the MPFI swap

 

does anyone have any clue how to get AC working again after a DPFI to MPFI swap.... sort of a big deal in 104 degree weather.
