check the EFI, then check the sensors for the catalytic converter. Should be one before and one after the catalytic converter. Also check the compression and fuel injectors. Not necessarily in that order.

Have you checked the circuit opening relay that is behind the dash just above the computer? I had the same problem in my toyota pickup with the same motor and it turned out to be that relay after I replace the pump, filters, fuel pressure regulator, and injectors.
