As it states, I was driving last night and a CEL light came on so when I was getting fuel I checked it with my Smarty. It was the same one as always for crank position sensor performance no big deal sooooo.... I cleared it started the truck back up and the Banks was dead and I've started and shut off the truck at least ten times since then so its not an intermittent problem. FYI its the 1st gen 6 gun with the ****.... Any help/ideas out there???
