No such thing as a pressure bleed, just a pressure fuel pressure test port on the top of the engine in the fuel pipe/rail that supplies the fuel injectors.

SOURCE: where is the fuel pressure regulator located at on

In the throttle body. You may need to have someone show you where exactly it is.

SOURCE: the brake system on a 2002 dodge durango has no pressure

Do you actually see brake fluid coming from the bleeders? Check for a broken brake line. If no fluid is being lost and the peddle has proper pressure, then the brake booster has failed. If their is no pressure at all, then the master cylinder has failed. Replace accordingly.

1989 Dodge Dynasty won't start after storage, can you help?

Have someone stand near the back, and listen for the fuel pump while you are attempting to start the vehicle. If there is no sound from the pump, it may be bad- A typical problem with tank mounted pumps after long-term storage. If there is fuel pressure, check for spark at one of the spark plugs. If it has fuel and spark, but still does not start, you will probably need a technician to look it over. Good luck, hope you get it going!

Why does my 1990 chev van start rough almost stalls then after two minutes runs fine

If there is a long crank that is a typical sigh of fuel preasure bleeding down, the first thing I would do is look at the fuel delivery system. With a fuel pressure gauge hook up monitor the pressure and see if it bleeds down after the vehicle has been shut down. Take a look the regulator by removing the vacuum hose while running and see if you see any signs of fuel coming out of the regulator, does not always happen right away may need to run for a few minutes

Has fuel pressure but not getting gas

The FIRST thing to do is scan your onboard computer network for possible fault codes. You may just have a code for a cranshaft position sensor or Mass Air Flow sensor or something similar that will explain why the engine is not getting any fuel.

Check the fuel delivery system to make sure it is performing according to manufacturers specifications:

The fuel pressure specification for 1999 Dodge Durango is 44-54 Psi. (3.0-3.8 kg/ Please note that the specification published by the manufacturer is with the key ON, engine OFF and the fuel pump being activated with a scan tool.

Also note that "CLOSE" is not good enough. I have had vehicles towed in that were only 2 or 3 Psi under the minimum specification that would not start.

If the fuel pressure/fuel delivery is within specifications, then you need to check your fuel injection system. If it gets this far, let me know and we can continue diagnosis.

New fuel pump and relay still wont start , spray a little fule down throught starts then dies

Hi Patrick,

The only thing I can tell you is that it sounds like you have narrowed the problem down to either a FUEL DELIVERY problem or a FUEL INJECTION problem (since it starts by spraying fuel in the intake).

You need to check for fuel pressure at the fuel rail to eliminate the fuel delivery system, (This should have been done before replacing the fuel pump and/or relay.)

If the fuel pressure is within specifications, then you need to diagnose your fuel injection system.

I have a 1989 ford f 250 302 efi im having a fuelissue i have found what i thought to be a fuelpump it comes on and everything with the key it is on the fuel rail toward the front of the truck but everyone...

Up until 1989, EFI fuel systems in the F250 actually used two fuel pumps; a low-pressure pump in the tank and a high-pressure pump mounted on the frame.seddy29732_7.jpgHigh Pressure Pump

The part on the fuel rail you are referring to is most likely the fuel pressure regulator, which, if bad can also cause fuel delivery problems. From 1990 and up, the two pump system was replaced with a single, in-tank pump.seddy29732_9.jpgHope this info helps you out!

If you can spray carb cleaner in the carb then you have either a fuel supply problem or fuel delivery problem. Check your fuel pressure and make sure it is in spec. Then check the spray in the carb spray.

How do you bleed air out of fuel lines after installing new fuel pump?

find fuel pressure test valve & hook up a gauge on it & do it the right way or stick something in the needle valve & release the pressure or raw fuel that will come out [[don't put ur face to close]]

Won't start

Check for fuel pressure at carb by placing a pressure gauge between the carb and fuel line . Check fuel delivery by putting a long hose connected to fuel line at carb and cranking. If you have pressure below 4lbs or if you get poor delivery cranking (with hose in a can or jar to measure amount) than you have either a bad pump or filter. If engine starts when you pour a small amount of fuel into it, and delivery and pressure was good, then there is a carb problem. When working on older vehicles, always make sure that fuel line from tank is not rusted and leaking.

A final addendum to the 1996 dodge dakota...

Here's the procedure for checking the fuel pump. I would 1st change the fuel filter, 2nd would be to scan for engine codes (free service at most parts stores), then check pressure (on a cool day, below 70 degrees) Good luck, let me know what u find. Curt
FUEL DELIVERY 1996 Dodge Truck Dakota 2WD 2.5L SFI 4cyl The Fuel System Pressure 44-54 PSI (Pounds per Square Inch)

Vent the fuel tank vapors by loosening the fuel cap and unplug the injector wiring harness from the main engine wiring harness. The next step is to attach an electrical jumper between a solid ground and the fuel injector terminal pin number 1. Next, connect an electrical jumper between the battery positive post and injector terminal pin number 2 for a period of time not to exceed 4 seconds. This serves to bleed down pressure from the fuel system. Install a fuel pressure gauge on the fuel rail service test port and energize the fuel pump. This will bring the system to a stabilized fuel pressure that can be visually verified on the gauge.
