It sounds on the surface timing related to me. But the fact that it ran ok and you haven't messed with it gives pause to that line of thought.

Thief was saying that if your fuel pump is running and the Pressure regulator is working right you will have proper fuel pressure.
Also, pumping the throttle on an EFI engine doesn't do anything directly related to fuel delivery, other than allow more air in, fuel metering is the MAF, FPR and ECU's job.

Stupid question maybe, but have you had the head off to check the gasket or done a compresion/leakdown test?
