Replacement engine in '98 Blazer. Old engine ran on this ECM, so the ECM is believed to be OK. Fuel pressure is 55 PSI.
Everything appears fine except that I am not getting any voltage at the injectors to make them pulse. The engine will fire when primed manually, but the injectors are not delivering fuel, so it's a short run.
All wiring and harnesses were reconnected as before. I do not have a manual, so I don't know what I should be looking for here. What's keeping the injectors from getting the electrical pulses?
Any help is appreciated.
