I swappd my d15b7 motor out of car, replaced it with a d15z1 motor, put in the computer from the d15z motor, replaced distributer, spark plugs plug wires, battery, fuel filter. ignition control module. tested evrything with a volt meter, including injectors, and air fuel mixture sensor. everything tests good. the engine cranks but doesnt fire up to idle, and drive. i have no clue what else to do. any help would be awesome!
