Fuel Injection System - Multi-Point: Description

The Electronic Fuel Injection (EFI) system on the 2.3L, 2.9L, 3.0L and 5.0L engines is a multi-point, pulse time fuel injection system, with a mass airflow sensor. Fuel is metered into intake air stream, according to engine demand, through injectors mounted on a tuned intake manifold.

An on-board electronic engine control (EEC-IV) module accepts inputs from various engine sensors to compute required fuel flow rate necessary to maintain correct air/fuel ratio throughout RPM range.

The EEC-IV computer sends a command to injectors to meter approximate quantity of fuel. System will automatically sense and compensate for changes in altitude. It will also permit push-starting of vehicle if necessary (M/T only).
