2003 Chevy Duramax, automatic. It starts, runs about a second, then dies and will not start again till it desides to start again. This happens about twice per month. I took it to service they changed the crank shaft position sensor, this did not solve the problem. truck also has a Hornet alarm with remote start etc.. I don't know if that might have something to do with it? I have also repleced the fuel filter. It also has BANKS. Any and all help will be greatly appreciated!!
