I have a 91 mazda 323 with 160,000 kms, the vehicle wasnt starting and when I did a pressure test by the fuel injectors, the pressure was low. I replaced the fuel pump and did a pressure check and the pressure was now correct. However at idling theres no pressure, any suggestions would be GREATLY appreciated.

Might be a faulty fuel pressure regulator.
