Look on the back side of the engine just to the drivers side of the distributor. You will see the two fuel lines. The test port will be on the larger line. It usually has a black plastic cap over it. Let me know if you have any questions and I'll do my best to answer them. Thank you for using!

I’m happy to assist further over the phone at

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.

The fuel pressure regulator is located under the intake plenum attached to the six in one fuel injector.They leak quite often causing hard start conditions.The injector is also known as a spider injector which will come with the regulator .

How do you check fuel pressure

You will need to rent a fuel pressure gauge from the local parts store.
Locate the fuel pressure test port, you may have to refer to service information to locate this port or you may have to T into the fuel supply line.

  • 2 Cycle the ignition key "on" and check your readings, write this number down. Start the car and run it, record your fuel pressure reading again. If your performance problem occurs when driving then you will need to take a road test to record the fuel pressure when driving. Tape the gauge to the windshield and have an assistant watch the gauge while you drive.

    Where is it on 2002 kia rio fuel test port don't

    You would have to test the fuel pressure on this vehicle by connecting to the line coming from the fuel filter to the fuel rail, there is no actual fuel test port on this vehicle. if you do decide to test the pressure... here is what your pressure readings should be>> Fuel Line Pressure 46-51 psi (320-350 kPa)
    This actually sounds like a Fuel Pressure Regulator issue. I would recommend replacing the regulator and see how the vehicle responds after that..

    Hope this helps...

    2002 chevy silverado starts right up but then dies right away starts right up again but dies

    By what your stating, that it starts and dies every time, It seems to be fuel related. You need to perform a fuel pressure check. You will need a pressure tester, one that would at least be able to read pressure to a maximum of 150 lbs of pressure. Although you really only need about 50-60 pounds of pressure to maintain proper fuel injector operation. There is a test port located on the fuel rail where you would conect the pressure tester. The test port is usually located on the drivers side of the engine near the rear section coming up from the firewall. Unscrew the pressure port cap if its still there and connect your tester. But also keep in mind you may have fuel pressure of some sort in the rail so be careful. While the tester is screwed to the test port you want to cycle the ignition key on and read pressure, you may want to repeat this several times. You must have at least 50 pounds of pressure, if so it should start. If you are losing pressure while your maintaining a visual check on the tester it could also be a faulty pressure regulator/fuel pump or even a rubber hose connection inside the fuel tank that connects the fuel pump to the fuel line. If you have any questions Im here to help. Thanks for using FIXYA

    1998 olds Bravada, runs great in the driveway, once in gear, i give it gas and it quits, only happens in cold weather

    Bad TPS will give you a SES light. Possible low fuel pressure from bad fuel pump. Put a fuel pressure gauge on the service port close to the firewall, should stay above 50 psi when juicing the gas. Only use OEM parts on a Bravada! Try "thepartsladi" store on eBay.

    How to know if fuel pomp is working properlyor not?

    The best way is to hook up a fuel pressure test gauge and see if the psi is sufficient. It hooks up to the fuel rail pressure test port and is usually pretty cheap to buy.

    These gauges are very simple to use, almost as easy as putting air in your tire and can be picked up from almost any auto parts store.

    If you go this route, I also suggest you buy a repair guide for your vehicle. It can show you exactly where the test port is located and what pressure your fuel pump should be outputting.
