Yes, he tried! Gigante's first attempt was the car bomb that killed Frank DeCicco. According to Gravano's book, two of members from the Gambino family conspired with Gigante to kill John Gotti and Frank DeCicco. But that day, John Gotti called Gravano and told him he was going to be late. Well, Frank DeCicco and another man (forgot who he was) went out to the car where Gigante had the bomb planted. The man with DeCicco looked like Gotti. The assasins were told that when they saw DeCicco and Gotti getting into the car, they needed to bomb the car. But when they did, the bomb killed DeCicco and the other man lived. This happened in the late '80s.
