Turning Over?
Is the engine turning over when attempting to sart? If you are getting a "clicking" noise check the battery cables from battery to starter and engine ground. The engine ground may not sound important, however, it was the culprit on my boat with this problem. It appeared to be grounded well, but when I put a new ground cable on it the problem went away.If your engine is turning over then it may be a glow plug problem. Also check your engine kill cable as sometimes it may get stuck in a halfway position.Do these checks prior to spending money...... I learned the hard way.Let me know what you find.Greg
