I’ve considered the fuel pressure - I haven’t checked it personally(I don’t have the tool), but at least two of the shops I had it at assured me it was good. I’m not sure how to test it while driving - and the problem is worst when first started up.
AFAIK, the fuel pressure sensor is integrated in the fuel pump module which I replaced (with a used one). The module (I believe) is part of the PCM, I don’t think there is a separate driver. The only thing on the fuel rail in the engine is the fuel pressure dampener, which I have not replaced - it is not leaking, but I don’t know how to test it to see if it has simply failed.
