[QUOTE="ioang26, post: 1564719, member: 27866"] Truck is fixed ,thank the Lord! Replaced the Low pressure rail where at the flex connection was a kink and the screeching noise stopped and no more blow off return line of injector#6. But there was another problem - Rail pressure at 6511 psi and at KOEO it would still shows 2600psi which was impossible. Cracked an injector line and no pressure at all , not a single drop and FRP sensor still shows 2600 psi. Turned out to be a defective FRP sensor which was BRAND NEW . Replaced it with another one and all pressures back to normal. [/QUOTE]
