Take off your fuel filter and see if you can blow through it if not replace it and see if this fixes your problem
SOURCE: 85 s-10 2.5l no fuel from the injectors
electronic engine control unit calculates the mass of fuel to inject, not how wide it sprays. It's the type of solenoid that you use. Some have wider spray nzzles than others. An external Fuel pump helps the delivery of the fuel. Also since fuel injectors rely on mass air flows nowadays, you have to have proper mixture coming through. hows your Fuel pressure regulator?
The throttle position sensor reports to the computer the position of the throttle butterfly valve, which the ECM uses to calculate the load upon the engine-but inorder for this to run, you may need an external pump.
Sounds like nothing is being grounded back to the ECM to even give a reading. If your regulator is improper and you do not have a external pump (depending on your model), than check those. If not, Start from scratch.
If you ever lose your way, go back to the beginning_REWIRE!
Goodluck.
SOURCE: I have no injector pulse.
There is an injector fuse. Pull an injector plug , 1 wire should have 12 volts to it. the other goes to the PCM. The PCM is set up so that it has individual injector drivers, Meaning that you could loose 1 or 2, but loosing all 6 at one time is very unlikely. Injectors do run off both crank and cam sensors, but mostly off the cam. And when the cam sensor does fail, The PCM goes into default mode, using the last stored run. Just a note... when you find the injector fuse pull it out, sometimes fuses just loose connection.
