You're quite welcome.
It's the ECU, 99 and 44/100% sure. The FPR will take high pressure gas from the fuel pump and knock it down to pressure range required for predictable fuel flow, but can't do much if the pump isn't pushing anything towards it.
The way FPRs usually go bad is that they either pass gas (as it were) through a breach in the diaphragm and into the intake manifold or the spring (or seat) goes bad and lets gas pressure at the rail go outside the ECU's ability to compensate by changing injector cycle length.
Your diagnosis is (expensively, I'm afraid) good.
Only 2 more days until you're mobile. Good luck with it.
