I have a 94 prelude si body ( previously an h23) with an 01 h22a4 in it. I purchased a obd1 dizzy to bypass the crank sensor and i am using a jdm h22a ecu. I recently purchased a set of h22a1 injectors so that i would have proper fuel flow but for some reason they wont fire!!!! NONE OF THEM and i doubt the previous car got struck by lightning and shorted them all out at one time. Furthermore my h22a4 saturated injectors still fire aswell as myy h23 injectors! could this be the resistor box causing them not to fire?????????? ANY SUGGESTION???? my buddy ran this ecu in a f22 prelude body with a h22a and his f22 resistor box worked fine with those injectors.

 

What engine harness are you using? Are you sure the injectors are fully clipped into the connectors and making good contact?

 

im wondering, lets say someone didnt know they were OBD1 injectors and didnt wire in the resistor box. but they still hooked up the injectors and tried starting the car up over and over and over. would that fry the injectors?
