Troubleshooting
Troubleshooting can be difficult. On the pages that follow is a list of possible problems. To make a repair to a problem, make reference to the problems and probable causes.This list of problems and probable causes will only give an indication of where a possible problem can be and what repairs are needed. Sometimes more or other repair work is needed beyond the recommendations in the list. Remember that a problem is not normally caused by one part, but by the relation of one part with other parts. This list cannot give all possible problems and probable causes. The serviceman must find the problem and its source, then make the necessary repairs.Fuel System Fault Diagnosis Chart

Remove Injectors: Always make sure that injectors are not damaged during removal as the valve tips can easily be damaged. Install Injectors: Make sure injector/cylinder head bore and seat are clean. See Testing And Adjusting for injector seal installation. If nozzle body or needle valve are worn or damaged, the nozzle and valve must be replaced.Troubleshooting Problem List
