Injection Control Pressure Leak Test: Notes

Removing Injection Control Pressure (ICP) sensor and inspecting level in oil rail will determine if oil is being supplied to rail. Removing inspection plug in top of reservoir will help determine if reservoir is full. See Figure. A reservoir that drains back after engine has not been operated for a long period of time can cause a hard start condition. If reservoir empties after filling, ensure it is being supplied oil from low pressure oiling system.
