Re: 90 Hatch no injector pulse
How are you coming to the conclusion that you don't have any injector pulse? Do you have power at all the injectors..? Most likely you've either wired something wrong or you've wired something wrong, or you've blown the fuse supplying power to the injectors because you've wired something wrong. All the injectors get power through the resistor box through one wire, and the other wire is switched to ground by the ECU.
So the three failure modes are (in no particular order):

- Bad wiring
- No power to resistor box
- Bad ECU
