SOURCE: fuel pressure regulator had no vacuum line connected
another engineers wet dream. think of it this way . what is normally in the intake when the engine is running.. answer vacume, hence the regulator gets its vacume without a hose connected to it as its already in a full time vacume chamber.no hose required . ps be carefull to seat the regulator and o rings securely into the housing befor you reattach the secureing metal clip.
good luck chris

Multi point injection systems run at about 45-55 psi. When the key is
turned on,engine off, fuel pump will run for a short time to prime the
fuel rail. At this time the tester should read normal pressure or a
little higher.
You need to use a pressure gauge and run it in-line with the fuel lines. Pop the hood and look to the left. Just above where the strut mounts you will see a round silver filter. You need to remove the fuel line there and place your pressure gauge in line of that.
Let me know if you need any more help.

Hello , fuel pump relay location is in the relay box by the radiator. The fuel psi regulator is on the fuel rail itself. The regulator looks like a small disk about 1.5inchs in dia. It will have a vacuum line running to it.
