Introduction

The problem that is identified below does not have a known permanent solution. Until a permanent solution is known, use the solution that is identified below.

Problem

The engines that are affected by this problem are 3056 and 3054. Incorrect troubleshooting may lead to a diagnosis that is incorrect. A diagnosis that is incorrect may lead to unnecessary replacement of the fuel injection pump.

The fuel injection pumps on 3056 and 3054 may incorrectly lead to an assumption of a problem.

Solution

Before the fuel injection pump is replaced, refer to illustration 1, 2 and 3 to troubleshoot the fuel injection pump. The illustrations should help to identify other possible problems with the fuel injection pump.
