    Yes, buy the workshop manual for your engine, and follow the trouble shooting instructions laid out therein. If it is an electrical issue, then a basic multi-meter such as you can get from an auto accessories store, or electronics shop, would likely be needed, These are reasonably cheap expenditures.
