Hi there, I see you posted on a question about a P1860 code set, my 1999 Suburban is giving me a hard time with this same code and I am not sure what to do, what you posted about the ignition switch makes me wonder if I got a bad one because my fuel gauge is acting funny and my fuel pressure is a little low, but I just replaced my switch for this 1860 problem and nothing changed, HELP
