I've been trying to get a friends 1999 k1500 suburban running. He ran out of gas, then got it running again, but it died the next day, and hasn't started since. He is a chef, and has no mechanical knowledge at all. His b-inlaw, changed the imline fuel filter, and it still would crank and not start. I started looking at it, and verified fuel psi at the schrader valve that feeds the injectors, and that there was indeed spark. So i'm figuring it is either clogged injectors, or the filter in front of the fuel PSI regulator, now here is my problem . The guy(s) I'm hoping will hep me already know what an abortion the new FI systems are on the 350, but for us ford guys, let me explain. To access the injector system sans the throttle body you have to remove this carbon fiber abortion of an intake(upper). Gone are the old set-ups that were so similar to the ford CFI system from back when. SO I removed the upper intake and replaced the fuel presssure regulator, that has screens and gasketsin front of it. There is no line on the FPI it just clips in place behind these gaskets, and screen filter. After reassembling, the truck tried to turn over briefly, then a loud click like a missing ground in the ignition system. When repeatedly tried, noticed smoke coming off the power cable going to the starter. I verified All grounds to the ignition system, and noticed there was gas leaking from the p-side exhaust. My ? to all u actual mechanics who know better than me is, is this a sign that the injectors are clogged and fuel is dumping from the relief on the regulator or did I install the regulator wrong, I swear I didnt take a line off it, and cant find one that I missed, but still having the same issue. Perhaps the GM gods are mocking me, but its annoying the hell out of me, I do all my own work, and have owned imports, as well as dodges, and all my fords over the years, and never had a issue, I couldnt solve, so any help will be appreciated, and hopefully, I am just missing something stupid.
