First, is there any check engine lights on? Also, did you locate the sound of the "tapping"? There's just way too many sources/sounds for me to guess.
Also, you said your truck broke down. But you were not specific. Did the engine stop and won't start now? Did the transmission fail to engage (won't move)? If the engine doesn't start, does it turn over when you turn the key?
