    Have you checked fuel pressure? When mine had a bad fuel pump, it would often idle rough when warm, and sometimes would take lots of cranking to start, or simply not start at all.

    Good thought, I have not checked fuel pressure. I am hoping the weather next weekend is good and I can do some wrenching.

    Scorched earth mission to renovate Njordi continues. I just order all new OEM injectors and seals, found an OEM fuel pressure vsv, and a Delphi brand fuel pressure regulator. An expensive bill for sure, but it feels like all these things are good to refresh even if they are not the primary problem.

    Have you verified spark yet? When you turn the key to "Run" position, do you see the little engine icon/light on your instrument cluster?
