You very likely DO have spark—otherwise the FI system will pump no fuel.

Your hunch on the Fuel Pressure Regulator is a good one. Remove the vacuum hose at the FPR and check for signs/smell of fuel. There should be none.

If the FPR diaphragm leaks, fuel will be sucked directly into the
intake manifold.
