Son and I rebuilt the stock 6.0 with 346k miles had blown head gasket and piston slap. Reinstalled and now crank no fire. Has fuel and air. We put two code readers (orange obd pocket scanner and a tuner scanner) and get zero codes. We had three codes and truck was in limp mode before we pulled engine. Now we have no codes, power to coil plug on each side and no fire coming out of any coils now. Grounds and 12v are good to new cam sensor and new crankshaft sensor, checked both at the plugs. All grounds are attached to block and checked with test light to 12v at battery. All fuses good, relays pulled and tested for resistance. Main coil plugs on both sides have 12v and ground coming in and no fire out of coils. Need to know if a real scanner can pull codes in memory or are they all erased since battery was unhooked for awhile? Do I need to get it flashed? Scratching head and watching ALOT of videos lol. Threw a few new parts at it Throttle body MAF Thanks for any input.

Ok, so I got the engine back together and started the engine. The engine turned over instantly. ran for a good 30 seconds to a minute.. before suddenly sounding like an exhaust leak happened. It ran rough. I quickly turned it off. Ever since then, sometimes it would start, but would run rough. Otherwise, just cranks, stumbles, acts like it wants fuel. I'm wondering is this could be due to bad timing. I won't rule it out since it was working prior to be taking it apart.. but as stated.. it was running well! * I did reuse the Actuator Valve Bolt... Could reusing this bolt cause this issue? * The ONLY code I had is the P00C6 code for Low Fuel Rail Pressure. * Research says this code is related to that damn bolt. (But primarily points towards the High Pressure Fuel Pump.) *Research says that High Fuel Pressure Pump is located on top of the lower intake manifold, below the upper intake manifold. I'm really like to know how to verify absolutely 100% that that's the culprit.
