Greetings, I've had a no start problem for over four months. Changed faulty injectors, changed fuel pump, changed crank sensor, changed fuel pump pressure regulator, changed glow plugs, changed ECU, changed fuel rail pressure sensor. It will run while pumping easy start, but will not catch on. Today I found that I'm only getting 2.8 volts across all four injectors when ignition is on. The resistance side seems to be okay. The 4 -hot wires from the injectors goes into a harness that splits before going to the ECU. What three plugs going to the ECU houses the injector voltage wires? And also which pin in the ECU to check for 12 volts going to injectors?

We don't have wiring for a Renault but did you do the test with any injectors still connected? If so recheck the supply voltage with all injectors and glow plugs disconnected. If one is shorted it will cause the voltage drop in the system.
