I have a b20b swap in my 1991 civic dx I got it converted to mpfi by the simple wiring and it runs but it sputters a lot the ecu is currently a throwing a code 43 which is a Fuel Supply System defective or malfunctioning fuel supply system, But I can't seem to find where the problem is. Any suggession will be greatly appreciated. :D
 
test your fuel pressure as well as searching for a dead cylinder which could be cause by a bad injector. if you find a dead cylinder swap the injector from that cylinder whit another cylinders injector and see if the dead cylinder follows the injector. . . good luck
