Multiport Fuel Injection

Safety Precautions


The fuel system is under pressure!

• Always wear protective eyewear and protective clothing to prevent injuries and fuel from coming in contact with your skin.

• Before loosening line connections, place a cloth around the connection point. Then release pressure by carefully pulling off the line.

To reduce the risk of personal injury and/or damage to the fuel injection and ignition system, always observe the following:

• Do not touch or remove the ignition wires when the engine is running or turning at starter speed.

• Only disconnect and reconnect the wires for the injection and ignition system, including test leads, if the ignition is turned off.

• The fuel pump is activated by turning on the ignition and by a door contact switch in the driver's door. If the battery was not disconnected, the connector - arrow - must be disconnected from the fuel delivery unit or the fuse for the fuel pump control module (J538) must be removed before opening the fuel system.







When doing any repair work, especially in the engine compartment, pay attention to the following due to clearance issues:

• Route lines of all types (for example, fuel, hydraulic, Evaporative Emission (EVAP) system, coolant, refrigerant, brake fluid and vacuum) and electrical wiring so that the original path is followed.

• To prevent damage to the lines, make sure there is sufficient clearance to all moving or hot components.

If special testing equipment is required during a road test, note the following:

• Test equipment must always be secured to the rear seat and operated from there by a second person.

If the test and measuring instruments are operated from the front passenger seat and the vehicle is involved in an accident, there is a possibility that the person sitting in this seat may receive serious injuries when the airbag is triggered.

- To conclude work, erase the Diagnostic Trouble Code (DTC) memory of the Engine Control Module (ECM) since malfunctions were stored by removing the fuse. Refer to => [ Engine Control Module DTC Memory, Checking and Erasing ] Testing and Inspection.
