Problem Solving.

Problem Solving.
Now that you are fully armed with some insights into the workings of both types of engines, I will now endeavour to explain some of the simple essentials used in fault finding.
The most important point to remember is that your fault-finding technique should be one of a "process of elimination". Start with the electrics, then move on to fuel and finally (once these have been eliminated) look for mechanical problems.
The following information will not be a substitute for a trained mechanic armed with many workshop manuals, but rather a conglomeration of tips and hints that will hopefully enable you to get out of trouble. It is, in my mind, advisable that everyone has some basic knowledge in the field as the knowledge and abilities of the local drivers cannot always be relied upon.
