i wrecked a 92 teg and i am putting the b18 into my crx, my crx is a dx so i had to do the mpfi convesion, i got it all in and its turns over, but wont start, im pretty sure that it is the injectors that arn't workin, do i need a 92 civic si ecu instead of the 91?

It's either the injectors or the ignition. First check your fuses. If they're good, then move on to checking the components with a multimeter or a noid light (yeah it really is called a noid light). Always check your stuff before you just go buyin new ones.

You need to realize that your engine is OBD1. If you are using the original injectors you do not need the injector resistor box and you said you have a 91 ecu, 91 what? If its a pm6 Si ecu thats OBD0. You ecu,injectors,dist have to match to keep things simple.

in short, use the ecu from the teg.
