While you may have the same symptoms as others, fuel pumps usually don't explode. The electronic throttle control message comes on any time that the jeep stalls or dies. First I would simply replace the fuel filters. The grinding noise that you heard may have been from the filters being clogged and the fuel pump straining to pull the fuel trough, especially as the fuel level drops. Just happened to me this week, soundedl like a whine and buzz from under my feet. New filters solved everything. Also if it was an explosion there may be some shavings in the fuel filter due to metal falling back down the lines that you could see. Hopefully its simple as a clog!
