Red top injectors, matched set. Known good. No issues prior to spinning rod bearing on original motor. Original motor: 3.0 bar FPR. Red top injectors, Jak Stoll chip in ECU. Those parts transferred to new /replacement engine that has maybe five miles on rebuild and was running perfectly the day I removed it from the donor car. Checked fuel pressure at rail again yesterday by cracking banjo fitting at front of rail. Fully pressurized. Not trying to be negative, I believe I've looked at almost all possibilities, (certainly it appears that there's one I've missed!). The problem exists in the SPG car itself's electrics. I have zero suspicion of the new motor/trans combo that went into the car. Reading an ohm meter and determining .5 millivolts? You might as well be speaking Russian to me. I don't understand electronic diagnostics at all. Embarrassing, but true. My idea of "testing" is to replace a questionable part with a known-to-be-good one. It's half-assed logic because it doesn't rule out a voltage issue being fed to the given component, but it's all I really have ever done to solve a problem.....and up until this, it's worked! Bob
