crank engine, engine fires, dies. no stumbling, just like a key off DIE.
FRP act vs desired is spot on, even when engine dies my frp hangs at about ~5500 for a few seconds.
SYNC stays good until engine makes its way back down until almost 0 RPM
blocked off EGR, do not suspect stuck valve choking out motor.
no exhaust restriction. full weight truck.
unplugged all 5v sensors, no change.
IF you press throttle on cranking it will stay running and then for the rest of the day it is fine.
new HPFP and harness.
