First thing to do is to build / borrow the Arthur Dalton design code reader (around $10 in parts) and read/reset/read the codes. Might be in limp-home mode already and have some issues.

Also, pull the vacuum line from the fuel pressure regulator (driver's side of the head, front of the fuel rail) and see if a ruptured FPR diaphragm is pumping fuel directly into the vacuum line, sounds likely.
