How do you change a fuel pump in a 1995 Pontiac Grand Am?

I have a 1995 Pontiac Grand Am, V6 engine. It's having a hard time starting up and running (it takes a few turns of the key and a couple presses of the gas pedal and than when I put it in gear it kind of chugs when I give it gas and than dies) my husband changed the fuel filter and it was pretty clogged up. He says the next step is to change the fuel pump but is not quite sure where to start on how to do it. How do you change the fuel pump?

it's in the gas tank, you have to take the tank down to get it out and the pump is very expensive to replace.

The fuel pump is probably located in the gas tank. Before he removes the pump, he should connect a fuel pressure gauge to the fuel injector rail to see if the fuel pressure is low.



If the fuel filter was%26quot;really clogged up%26quot;, you probably have contamination in the gas tank. Either someone dumped dirt in it or it is rusting and particles clogged the filter. If it was clogged so much that he noticied it, the fuel injectors may also be clogged.



I suggest you start with the pressure test first. If pressure is okay, I would then work on the injectors.
check the fuel pressure first..changing the pump is alot of work and is quite expensive just throw some parts at it without diagnosing first... there's a test port on the fuel rail...double check me (i dont know what engine is in your car) it should be around 50 psi
you have to drop the gas tank off of it to get to it,and its a hard job, if there's any gas left in the tank it makes the tank really hard to handle,its not an easy job either,but if you can get some help with it then it would be easier,but for the hassle of it id pay to have this job done,i own a shop ,and even i hate seeing these jobs come in,gas is dangerous,and it would pay to have this one done,and its a lot safer also,good luck with it hope this helps.
jack up the car....supprt w/jackstands...pull the gas line lose...put a jack under the tank.....remove the support straps...the tank should lower with the jack...this is best done when there is a small amount of fuel in the tank
I would suggest trying this site. It's very informative and helps me from time to time.



Good luck!

Well hopefully you are low on gas. But you have to drop the fuel tank. There should be two straps that hold the tank up to the body of the car. You have drop them and then you should be able to see the fuel lines going into the tank. Take the lines off the sending being carefully that you don't brake anything, these metal lines are probably very rusty and brittle. You should see a large lock ring around the base of the fuel sending unit. You have to some how turn that lock ring, most people use a chisel and a hammer. After you get that off you should be able to pull the sending unit out of the tank. There are two types of fuel pumps that might be available for your car. One is a complete unit that includes a fuel pump that is already installed into the sending unit. Or what they call a cut away, which means you can buy the pump and strainer and install it into the old sending unit.



Hope this helps.
