Well, I was cruising about 60mph and then attemped to accelerate. About 3 seconds later my truck made a backfire feeling and the engine shut down. All my dash lights were still on. It felt like I blew a tire. I looked in my rearview and saw a small puff of white smoke. The turbo is still intact. All gauge readings were fine. It pulled a 1693 code. I attempted to restart it after about 10 minutes. It cranked fine with no abnormal noises but it just wouldn't fire. Sounds like a new VP44 to me. What do you guys think?
