Another interesting wrinkle in this Subaru VW bus swap! It seems my hard start issues are relate to fuel system. Over several days I was monitoring fuel pressure when the bus just sat and overnight sometimes the pressure would drop to 0psi. ALSO, I noticed the half tank of fuel I had vanished with very little driving and lots of sitting. So I yanked plugs and found 3/4 were wet with gas after sitting all night! So obviously my injectors are leaking and causing foul problems! None of this was apparent as long as the engine was running, no smoke or rich running symptoms.
Full disclosure: My swap vehicle was a high mileage engine, albeit a well cared for one in good shape. I flipped the intake on this swap, leaving the fuel rails in stock ornamentation so I had to pull injector rails and reinstall them.....twice(don't ask). I did not replace the O-rings on injectors. AND I am ashamed to say...I DID NOT replace fuel filter for the swap.
So...reman injectors on their way from Rock and we'll see what happens then.
Thanks everyone for contributing to this issue!
