SOURCE: Where is the fuel pressure regulator located at in a 94 bravada

My friend, I suggest you go by your local Auto Parts Store and purchase a Haynes Repair Manual on this vehicle. There are many sensors and electronic controls involved with this engine as I'm sure you already know. Any one of these can memic something that "it is not".
If your problem is the Pressure Regulator, it is located inside the "Tunnel Ram" intake manifold along with the multiport fuel injection system.
Now,,, before I went through the trouble and expense of going into the Intake Manifold, I would run the EMC in Diagnostic Mode and see if there are any codes present.

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 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

SOURCE: how to check fuel pressure regulator 1990 300zx na

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.

1990 subaru legacy wagon fuel injectors are not getting fuel to start it

Check the pressure to the fuel rail then check it at the line before the fuel pressure regulator, it should be between 55 and 80 psi at the rail and 100 psi before the regulator, if you don't have pressure before the regulator then you have a fuel pump issue, if the rail pressure is low then you may need to replace the regulator.

How to replace injectors 1990 corvette


See Figures 1, 2, 3 and 4
Before performing any service on the front or rear TBI unit, you must place the unit in a suitable holding fixture such as J-9789-118, BT-30-15, or equivalent. If you dont place the unit in a suitable fixture, the throttle valve may be damaged.

  1. Disconnect the negative battery cable.
  2. Remove the TBI unit from the vehicle, and place it in a suitable holding fixture.
  3. Remove the fuel meter cover, as follows:
    1. Remove the 5 fuel meter cover attaching screws and lockwashers.

Fig. Fig. 1: Exploded view of the fuel meter cover attachment

  1. Lift off the fuel meter cover with the fuel pressure regulator (rear unit) or accumulator (front unit), noting their positions for reassembly.
  2. Remove and discard the fuel outlet passage only. Leave the fuel meter cover gasket on the fuel meter body.

CAUTION Do NOT remove the 4 screws securing the fuel pressure regulator or accumulator to the fuel meter cover. The regulator or accumulator includes a large spring under heavy compression which, if accidentally released, could cause personal injury. The fuel meter cover is serviced as a complete assembly only. On the rear unit, the fuel meter cover includes the fuel pressure regulator which was calibrated and plugged at the factory.

Fig. Fig. 2: Bottom view of the front and rear fuel meter covers
Do not immerse the fuel meter cover (with the pressure regulator or accumulator) in any type of cleaner. Immersion will damage the internal diaphragms and gaskets.

  1. Remove the foam pressure regulator sealing ring (dust seal) from the rear throttle body.

When removing the injector, be careful to avoid damaging the electrical terminals on top of the injector, injector fuel filter and nozzle. Do NOT use pliers to remove the injector, as this could cause damage. The injector cannot be disassembled and is serviced as a complete assembly only. As it is an electrical component, it should not be submerged in any type of cleaner.
  1. With the fuel meter cover gasket in place to protect the casting, use a suitable prytool and a fulcrum, as shown in the accompanying figure, to carefully lift the injector until to is free from the fuel meter body.

Fig. Fig. 3: Carefully pry the fuel injector out of the fuel meter body

  1. Remove the injector. If removing both injectors, make sure to mark them front and rear, so they can be reinstalled in the proper position. The injectors are NOT interchangeable and cannot be switched during installation.
  2. Carefully rotate the injector fuel filter back and forth, then remove the filter from the base of the injector.
  3. Remove and discard the fuel meter cover gasket.
  4. Remove the large O-ring and steel back-up washer in the top counterbore of the fuel meter body injector cavity. Remove the small O-ring located at the bottom of the injector cavity.

Try clamping the fuel return line with the appropriate tool that wont damage line and see if it improves if so you need a fuel pump or pressure relief valve.I know you said you had fuel pressure but you took that reading while vehicle was idleing so you cant check for pressure in above idle conditions.Is your air cleaner assembly as original with no holes or leaks from air box to throttle body?Its more likely to be a mass air flow meter.This problem occured to my vette while i was on holiday there.cost$89 exchange.good luck

Engine surges only after it warms up!

It sounds like an intake manifold vac leak. After the engine warms up use a can of spray carb cleaner at all edges of the intake. Use short bursts of the cleaner and see if the RPM changes. If it does you have a vac leak. That means replacing manifold gaskets.

Looking for fuel filter on 1990 corvette

The filter is underneath on the passenger side behind the front wheel. Release the pressure first, or you will get sprayed with gas.
