N55 FBO PI e85. Starts are pretty bad whether cold warm or anything. Long cranks sometimes, no signs of weak hpfp. any suggestions?

Have you tried to go back to pump fuel to see if it still does it?

Check Fuel Pump Regulator

And By "Check" i mean replace. The symptoms your experiencing is a prime example of a failing regulator. FCPeuro FTW on this specific part, Wear double gloves...thank me later. Good Luck
