How to release fuel pressure to replace fuel filter on a buick rendevouz 2004

follow the fuel line under vehicle by tank will see filter inline one end has a female thread the other is a press release

Auto choke is sticking, If you do lots of short runs this happens. Your local car accessory shop will get you a spray to use.

You are correct there is a third connection from the Headlight assembly to the car but it is made with the white pull-up connector. There are actually two plastic studs that are both holding the lamp assembly to the vehicle but they are both released with the one white pull-up clip. Make sure you are pulling up and forward on that clip to release the hold on the HL assembly. After you remove the white clip and the side fastener the HL assembly will come out. Sometimes you will have a wresting match with it to pull it free as they do get stuck after time. One way I loosen them up is by smacking them with an open hand with just the right amount of force, just be sure not to hurt you or the assembly and take off your rings.

well if thats a sure thing all you need to do is buy the part from dealer or aftermarket, then relieve the fuel pressure by pressing the little valve that looks like a tire valve stem on the fuel rail which will release fuel pressure, disconect negitive battery terminal, and then all you need to do is remove old line and replace with new line, you will need some fuel line disconect tools which can be purchased, this is the best pic, the release valve is on the fuel rail there and ou take the cap off and press on valve

release the pressure firs like take gas cap off there are some speacil tools called quick release tools some people just use a small screwdriver to pop it off it should be on driver side by the drivers door under neath the car if its a four door this driver door im talking about

maybe check for a bad relay controlling the fuel pump

The fuel filter is located inside the frame rail, just ahead of the passenger-side wheelwell opening. It has a threaded fitting on the forward end, and a quick-release clip on the back hose attachment.
Caution! The fuel is under pressure. Wrap a rag around the quick-release fitting as you release it, to catch any spray. or first relieve the pressure at the test port on the injector fuel rail (under the plastic engine cover), again using a rag to catch the fuel spray. Wear safety glasses, and only do this when the car is completely cooled off. You WILL spill some fuel while doing this, so have a catch container, and/or spread oil-dry/cat litter on the ground under the filter area. After changing the filter, turn the ignition "on", which powers up the fuel pump, but do not start the car. Now check for leaks at the filter, and at the test port, if you used it to bleed off fuel pressure. If everything is dry, you are OK.

The fuel filter is located underneath the car in front of the gas tank.
You have release the fuel pressure. Remove the fuel filler cap, locate the fuel test port on the fuel rail on the passenger side on the end of the right real fuel rail for a 3.1L engine.
3.8L engine yhr test port is located at the pressure regulator under the trim cover.

the fuel filter is located under the car near the outside frame it is just connected with two quick connects just release the fuel pressure before unhooking the filter and watch your eyes a little gas will come out of the filter
