In a sense, the injector control wire can be looked at like a garden hose with a trigger type hose nozzle on the end. Water pressure is in the hose as long as the trigger grip is closed. That is analogous to your 12 volts when the scope signal is high.the fuel rail. A return line from the fuel rail takes excess, or bypass, fuel back to the vehicle tank. Your fuel pump should be mounted under the floor near the fuel tank, or inside the fuel tank. Connected to the harness power feed, the fuel pump will operate for 2 seconds when the ignition is turned on. It will Wiring Code Identification Information . WIRE CODE IDENTIFICATION . Each wire shown in the diagrams contains a code (Fig. 1) which identifies the main circuit, part of the main circuit, gauge of wire, and color. The color is shown as a two-letter code, which can be identified by referring to the Wire Color Code Chart (Fig. 2).Oct 16, 2019 · The fuel injector outputs drive the fuel injectors to allow measured amounts of fuel into the engine. These signals are on/off control signals that are varied by duty cycle. The more fuel is required the higher the duty cycle will be. The injectors are connected to common positive and the drive signals from the ECU is ground signals.

(invain) Well, we fixed the voltage problem, there was a short in the power wire for that injector and the connection back in the harness was pretty ****ty too. 12 volts at the injector plug now, but it's still not firing. We've checked continuity for the ground wire back to the ecu for that cylinder and ....
