1989 Nissan Truck 4 cyl Two Wheel Drive Manual

so I posted about an 89 nissan d21 2wd 2.4L. It still is not getting fuel to the inside of the throttle body. And the fuel pressure regulator is new and everything is plugged in. The injector is pulsating. And there is pressure in the fuel line. And when I try to give it a little gas when starting the injector makes a sound. The injector has 1.5 ohms as spec. What else could it be?

I am just an ole shade tree mechanic kind of guy, but one thing you might check are the trouble codes. For example, if the throttle position sensor is bad, the computer may not signal the injector to open enough (or at all), even if fuel pressure and everything else is correct. Also, you might try to "hotwire" the injector, so that it is wide open, and not trying to pulsate. Again, if you have a computer trouble code that says your crank angle sensor is not functioning, the injector may be being told not to open enough, (or at all). But if you hotwired the injector wide open, for a very short time, so as not to burn it up, (they are not made to stay on, but rather pulse), you might eliminate a lazy injector (even if has the proper resistance). Anyway, just my two cents worth.
