SOURCE: Mazda B2600i
are there any fault codes present? i was looking at the fuel injection diagram on autozone.com and the only thing i can see that controls injector pulse width is the pcm. are all the injectors open for 15ms? you should also check fuel pressure. if you want to look at the diagram, go to autozone.com. register and enter you car. select repair guides, chassis electrical and the wiring diagrams
