FUEL SYSTEM (Programmed Fuel Injection)
SERVICE INFORMATION
GENERAL
• Be sure to relieve the fuel pressure while the engine is OFF.
• Bending or twisting the control cables will impair smooth operation and could cause the cables to stick or bind, result-
ing in loss of vehicle control.
• Work in a well ventilated area. Smoking or allowing flames or sparks in the work area or where gasoline is stored can
cause a fire or explosion.
• Do not apply commercially available carburetor cleaners to the inside of the throttle bore, which is coated with molyb-
denum.
• Do not snap the throttle valve from full open to full close after the throttle cable has been removed. It may cause incor-
rect idle operation.
• Seal the cylinder head intake ports with tape or a clean cloth to keep dirt and debris from entering the intake ports after
the throttle body has been removed.
• Do not apply excessive force to the fuel pipe on the throttle body while removing or installing the throttle body.
• Do not damage the throttle body. It may cause incorrect throttle and idle valve synchronization.
• Prevent dirt and debris from entering the throttle bore, fuel hose and return hose, clean them using compressed air.
• The throttle body is factory pre-set. Do not disassemble in a way other than shown in this manual.
• Do not push the fuel pump base under the fuel tank when the fuel tank is stored.
• A lways replace the packing when the fuel pump is removed.
• The programmed fuel injection system is equipped with the Self-Diagnostic System described (page 5-7). If the mal-
function indicator lamp (MIL) blinks, follow the Self-Diagnostic Procedures to remedy the problem.
• When checking the PGM-FI, always follow the steps in the troubleshooting flow chart (page 5-11 ).
• The PGM-FI system is provided with a fail-safe function to secure a minimum running capability even when there is any
trouble in the system. When any abnormality is detected by the self-diagnosis function, running capability is secured by
making use of the numerical values of a situation preset in advance in the simulated program map. It must be remem-
bered, however, that when any abnormality is detected in four injectors and/or the ignition and cam pulse generator,
the fail safe fu nction stops the engine to protect it from damage.
• Refer to PGM-FI system location (page 5-5).
• A faulty PGM-FI system is often related to poorly connected or corroded connectors. Check those connections before
proceeding.
• Refer to procedures for fuel level sensor inspection (page 20-19).
• The vehicle speed sensor sends a digital pulse signal to the ECM (PGM-FI unit) for computation. Refer to procedures for
vehicle speed sensor inspection (page 20-12).
• When disassembling the programmed fuel injection parts, note the location of the 0-rings. Replace them with new ones
upon reassembly.
• Before discon necting the fuel hose, release the fuel pressure by loosening the fuel hose banjo bolt at the fuel tank.
• Always replace the sealing washers when the fuel hose banjo bolt is removed or loosened.
• Use a digital tester for PGM-FI system inspection.
