My experience with gas BBQs is that the ignitor is usually the first thing to go. Usually, again in my experience, it happens due to corrosion of the ignitor itself. My solution is usually just to use a match, I find that the ignitor stops working so quickly that it's not worth replacing. Replacing the grills, heat spreader, and burners however makes a lot of sense and can make an old BBQ virtually new again.
