Fault Code 1117

[Biglentil]

I think the 1117 code is from us turning off the battery disconnect switch too quick after shutting off ignition. I think you are right about fuel. When I remove the fuel filter and turn on ignition the fuel stream is tiny almost just a drip. So thought maybe a restriction towards fuel tank so I put the suction hose from lift pump into a jug of diesel it sucked it down pretty quick like I would expect, probably a gallon a minute rate or so. However the fuel stream out the fuel filter housing is still
tiny. Cant be right can it? I'm thinking it's the integrated check valve at the lift pump. Not sure if its serviceable. Will let you know.
