05 6.0 zero boost
Driving today pulled away from a stop light and had zero boost. It felt as if the truck went into limp mode as it was low on fuel , got fuel and still starts right up but the boost gauge reads zero, WOT will get me to about 2800 rpm's. The truck is very sluggish and struggles to shift and go fastest than about 35 mph. I checked all of the turbo hoses, cleaned the EGR reset all codes but still no luck. I believe the codes were crankshaft position sensor, and a FICM low pressure code? Any help would be greatly appreciated.
