[QUOTE="FourEyed, post: 1546221, member: 11078"] Any help would be appreciated. I have 1500 miles on a complete rebuild of my truck. 200k on the body, but HPFP, injectors, turbos, engine, etc were all just replaced. Yesterday all was good all day. Stopped at a store, shut it off, and when I came out, it cranked over (very fast) and would not start. Got truck towed home, checked fuses, a couple simple things, and then after attempting cranking over a couple times it fired up. Shut it off and re-started it a bunch of times everything was ok. Today went to work, all good. Then made one stop at home and truck did the same thing. At least it's in my driveway this time, but I need to get this figured out ... - Tach is reading as it is cranking - ICP on mini maxx reads 7.0 - 7.4 while cranking - I can hear the low pressure fuel pump running - Seems to turn over very fast, like there is no compression. but it ran fine until parked. - Full tank of fresh fuel - Only code on tuner is P0703 brake switch B circuit. I did just replace the booster, so might be left over from that. Any suggestions on where to start looking? [/QUOTE]
