Here we go again...

So I'm not paying attention and let the front tank run dry. Noticed when it started running rough and switched over. Now it won't run normal, like there's air in the system. It runs rough when it runs, and takes a lot of cranking to fire up. There's fuel in the separator when I **** the drain open, so I don't think it did anything to the pump. Don't have a way to pull codes ATM so I'll have to get to that. Any ideas in the meantime? It's definately fuel related, HPOP reservoir is full, ICP is good.

fill that tank up a bit and open your fuel filter cap and let it sit over night to drain the air out...that might work...although i think PSDs are pretty good about getting rid of the air in the system on their own. Now you know (im sure) there is no pump in the tanks...on a fuel level sender...the only pump you have is in the valley. so i think that if you take the cap off over night and let it bleed out it might help.

It's throwing a P0344 code, but the CPS is brand new. Swapped with one I knew was good and same story. I think the fuel pump went out, I guess its been weeping fuel for a while since I noticed fuel when I changed the oil last time but I couldn't find the source. Chalked it up to a bad seal on the fuel filter cap. Guess I know better now.

if there is fuel in your valley than yeah its toast...those pumps have a weep hole in the bottom of them and they leak fuel into the valley...awesome design.
