Replace it with a new one.
In order to answer this you need to be more specific as to what fuel problem you are having. Is it a fuel pressure problem? or a fuel injector problem. I would suggest you go get the fuel pressure checked to begin with. That can usually tell you if the fuel problem is from the fuel tank to the fuel rail or if the problem may lie in the fuel injectors. A weak fuel pump or a clogged fuel filter may be the culprit. If your pump is good and the filter is clean, then one or more injectors may be clogged not allowing the fuel to get to a cylinder. The fuel pumps job is to deliver the fuel to the injectors, the fuel injectors are designed to deliver the fuel to the engine beit through a throttle body or a bank of injectors or single injectors made for each cylinder. Start with a fuel pressure test and see where that leads and then come back and repost.
Pumping fuel to the injectors is one of the way of telling if the fuel lines are frozen. The remaining fuel that will be unused will be returned back through the return line.
check your ignition module it send pulses to ecm to tell it to pulsate the injectors
turn your car on, then unplug the fuel injector circuit one at a time...check to see if the motor shakes after u unplug it... if it does, plug it back in and try another one...if it doesn't shake like the others that's the bad one...
I had the same symptoms with my 90 non-turbo "Z". It did end up being a bad fuel injector. While it was being fixed and the had the injectors exposed, I had all of them changed so I wouldn't have to pay the labor if this happened again.
loosen the fuel line and if fuel squirts forcefully out the pump should be good,but it's really hard to tell pressure wise if you have fuel injectors they need a specific pressure to run.
check the tubing :)
As you did not list what model Buick you are referring to it is impossible to answer your question. All I can tell you is to follow the fuel line from the fuel tank to the engine and you will find the fuel filter.
not enough information is really given here, what engine? is it cranking over (meaning when you hit the key does the engine turn)? do you have fuel? do you have spark at all plugs? is the fuel filter clogged? is fuel getting to the injectors?
If it's a 95 then you don't have a carburetor, you have TBI, or Throttle Body Injection. This basicly means that there are two injectors that spray fuel into the throttle body sitting on top of your intake plenum. To see if they are spraying fuel just have someone turn over the truck while you watch the injectors. Don't forget to takeoff the air cleaner housing first!
It all depends on what year it is. and it will tell you in your owners manual if you can use what they call "flex-fuel". and don't let mechanics tell you that they can convert your engine to a flex-fuel engine. they pretty much have to rebuild everything from the pistons and camshaft to the fuel injectors. The some Saab 9-3's car use E85.
