Well reset the passcode by following my lock smith told me to do and was still having issues so a friend came over took him 5 hours but he got it started and it now is in limp mode for whatever reason... I have new battery fuel filter system cleaner does anyone now where the reset button is for the truck. Gm told me that the 2001 gmc 3500 didnt have a passkey but mine did and told me a few other things that were wrong so If anyone can tell me where the reset button is it would be great
