I have an 02 lb7 that I tried to do an upper cylinder and injector cleaning. I hooked it up like I've see all over the place. Hooked up to the 3/8 and 1/2 feed and return lines. It ran for about 5 min then shut off (about the time to run the fuel out of the filter) after not starting again I kicked the idea of cleaning it at the moment. I re connected the lines and primed the fuel filter. And still won't start. Any ideas out there on how I can get my truck started?.
