About this document
High Leak-off Testing for C4.4 & C6.6 Engines by wrya hussain is a document available to read on EtoBox.
The document provides a test procedure for measuring high leak-off rates of electronic unit injectors on C6.6 and C4.4 engines. It describes how to use a fuel leakoff kit to measure leak rates and determine if they exceed thresholds of 38 mL for six-cylinder engines or 25 mL for four-cylinder engines over 30 seconds of cranking at 150 rpm. High leak rates can prevent the engine from starting due to insufficient fuel delivery. The procedure is used to diagnose engines that crank but fail to start.
