Truck lost power ?

Hi. My truck 2016 6.7 lost power after Driving it pretty hard for a few miles. Ezlynk PPEI V4.0-LBF pos soft 2. Not towing and no horrible noises heard. There was barely any throttle response so i pulled over switched it off, turned it back on again heard my Fass pump prime started a driven normal after. So i'm guessing maybe fuel issue somehow? truck did this few years back so i fitted the Fass and i thought id solved it ? The truck has no erg n stock turbo. Any Ideas? I'll scan for codes today. Filters ? if all are dirty n limiting fuel flow but why have to switch the truck off ? i would think coming off the pedal for a few miles fuel pressure would return. I see the Code P01C6 is the result of the SOFT being plugged in, and the P062A is the stock fuel pump being unplugged. I realized i have been lazy with my fuel filters and not changed them in maybe getting upto and year 10km driving so ill change all 3 should do anyways.


fuel codes.

code scan for sure.

Fuel pick up blocked and it ran out of fuel. Low fuel pressure reading.

When i changed the pump out i also had to drop the tank for installing the new oversized piping for the pickup I'm sure the old pickup wasnt blocked, So chances of both stock and new oversized pickup tubes being blocked are slim i'd say. .

Do some searching online and here for those specific CELs if you haven't gotten to the bottom of the problem.

Did this just happen after you swapped out the DFCM for the FASS? Have you got a hold of FASS with this?
