ok guys i just put a b18b1 into me eg 4d and i wired in the distributer and altinator . the car turns over but it wasn't gettin fuel due to fuel pump not turning on ( dont think its bad because it worked fine befor i swapped the motor ) then when i was turnng the car over i smelt burning electronics so i pulled my ecu and when i opened it smoke billowed out . i need help asap anyone have an idea of what might be happening ?
