In-Tank Reservoir (ITR)

DIAGNOSTIC NOTE

Almost any electric fuel pump malfunction that can occur will result in a reduction of fuel flow and/or pressure. A reduction of fuel flow and/or pressure will be detected by a reduction in engine performance. This diagnostic procedure will concentrate on determining if the electric fuel pump system is operating properly. Other diagnostic malfunctions that can cause losses or reductions of engine performance.
The following diagnostic procedures are to be performed to determine if the electric fuel pump(s) are operating correctly:
