Fuel-Cut System

The fuel-cut system will stop fuel injection during deceleration to prevent excess fuel build-up during periods when oxygen is insufficient for combustion (i.e., closed throttle deceleration). Fuel-cut system will also deactivate injectors when engine speed exceeds 6800 RPM (Samurai, Sidekick and Swift SOHC) or 7500 RPM (Swift DOHC). This is done to prevent engine damage due to excessive engine speed. As engine speed drops to less than 6800 RPM (Sidekick), 7460 RPM (Swift DOHC), 6500 (Samurai) or 6600 (Swift SOHC), injection will once again occur.
