Did you install a new fuel filter? If so, have you replaced the stock FPR?

i did install new z32 fuel filter, but the fpr is stock.

Could be a blown diaphragm in the fuel pressure regulator. That wouldn't let the pressure build up.

That's what I'm thinking. Replace the FPR and I'll get that fixes it.
