the fuse block is the problem, but gm has not had a recall. There are three relays one for the start , igniation and a smaller one for the fuel pump. if you check the relays and especailly the smaller one you will find the contacts burnt and oxidizeds, try cleaning and using electrical grease and replace worked for us Paul
