To drive the fuel injector, the FICM produces two control signals for each injector. The open coil is driven (via a 20A pulse) to open the injector. This shifts the spool valve in the injector to the open state. Once this has taken place, high pressure oil is directed on top of the injector intensifier piston. In result, fuel•Only use hard fuel lines when using proper EFI rated flared fittings. Make sure that you remove ALL low pressure flex joints on factory fuel lines and replace them with EFI rated fuel hose and use proper flared connections and clamps. Be careful not to mix 45° and 37° AN fittings , they look similar but will not work together. 45° fittings The fuel injection wiring harness provides power to the injectors and the oxygen sensor, which determines how much fuel is needed for maximum efficiency. Over time, the fuel injection wiring harness can be damaged and needs to be replaced. If you notice your vehicle is idling roughly or misfiring or your engine isn't performing normally, be ... Chrysler fuel injector wiring harness is a known problem. Most car makers run power to the fuel injectors on a common wire. The PCM then provides the ground to each fuel injector on an individual wire as it fires each injector. Unfortunately, Chrysler injector wiring harnesses are a known failure item, especially where the harness routes near ...fuel injector stays open. 7986 Views 8 Replies 4 Participants Last post by Kirsa , Apr 2, 2015 Jump to Latest.

The codes are p0304 and p0204 I have changed both the coil and injector and suspect the Harness to be the culprit.I'm thinking either a ground short at/in the connectors, a short in the wiring from rubbing, or the common 2/7 injector connector faults Its kicking these codes, which make me think a wiring short as well: P0202 - Inj circuit / Open Cylinder 2 P0203 - Inj circuit / Open Cylinder 3 P0205 - Inj circuit / Open Cylinder 5 P0208 - Inj circuit / Open ...Cadaholic said: I have an important question. The fuel injectors have two pins. One pin is connected to the battery through the ignition relay and the other pin goes to the ECU. The ECU sends a pulsing ground to the injector, which closes the circuit, providing the injector's solenoid with current. The wiring harness connecting these two is ...Fuel Injector Wiring Basics. The fuel injector wiring diagram will show the connections between the fuel injector, the engine control unit (ECU), and the power supply. The power supply is typically a battery or an alternator. The ECU is responsible for controlling the fuel injector, and it will receive signals from the sensors in the engine ...DTC P0203 stands for “Injector Circuit/Open – Cylinder 3.” It’s logged when the PCM detects an issue with the fuel injector or its wiring. A logged P0203 can cause your vehicle to exhibit symptoms, such as an illuminated check engine light, decreased engine performance, and increased fuel consumption.You can find the fuel injector test here: How To Test The Fuel Injectors (1992-1995 1.5L Honda Civic).

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.Mustang Wiring, Fuel Injection, and EEC Information, Use the information at your own risk.

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.Remove the fuel injector wiring harness. ClWarning: Do not drain the fuel into an open container.

Tips on selecting the proper type of fuel injector connector. Fuel injector connectors are susceptible to deterioration due to aging, and wear and tear. A fuel injectors location on the engine exposes them to intense heat, vibration, and chemical fumes. Over time, these will cause the connectors’ nylon body to deteriorate and eventually break.The fuel injectors are responsible for controlling the amount of fuel that enters the engine and the timing of its delivery. Modern vehicle systems typically also meter the amount of fuel delivered through the fuel injectors with the help of the vehicle's electronic control module (ECM). Fuel injectors replaced carburetors as the primary ...The Jaguar XJS V12 wiring diagram clearly outlines the entire electrical system used in the model. It shows the locations of the central fuse box, circuit breakers, capacitors, wires, and other components that ensure the vehicle performs efficiently. In addition, the diagram is color-coded and clearly labels each circuit so that owners can ...Black-Orange is injector power, as you already found out. The other wire is the 'negative' pulse that actually fires the injector. Since they are paralleled (I think the 4-cylinder is also run in pairs - though the diagrams show them spliced together, which may or may not be true), the other side should read basically the same DC voltage whenever the injector isn't firing (which is most of the ...
