94 Chevy K 1500 5.7 V8 small block automatic

Asked by Fire Jun 13, 2022 at 08:05 AM

Question type: Maintenance & Repair

Kind of in desperate need of help I'm not getting
any fuel to my injectors. I have spark I used a noid
light and a test light and there's no power to the
injector plugs at all. I've read a lot of reviews and
traced wires back to the e c m. ECM is new TBI
was rebuilt new fuel pump new relays new fuses
new inline filter new injectors new pickup coil new
ignition module new ignition distributor new plugs
and wires add still nothing. Any and all help is very
much appreciated.

The ECM only provides the grounding or trigger signal so if there is no power then you need to test the power supply side of the circuit, easiest test first, check for a blown injector fuse in the power distribution box under the hood, now there was a known problem with some of the main power distribution boxes burning out some circuits and also the power wire from the battery to the distribution box.

Check the crankshaft position sensor. If the ECM doesn't know the engine is cranking, it won't fire the injectors. Also on OBD I GMs a bad coolant temperature sensor can cause a no start condition. Hope that helps! Jim
