I hate fuel pumps?

Question

Ok, so my car was having troubles starting on hills. And eventually wouldn't start, so i replaced the fuel filter.

Then a week later, the car wouldn't start again, it was water in the fuel lines, fixed that.

Now, it still has a hell of a time starting on hills.....is my fuel pump going?

If so, should i replace it with a new one or use, and how hard is it to replace?

1993 MX6, 200,000 miles. But im pretty sure the fuel pump was replaced 2 years ago...

I've never had it tuned, and have driven it for 60,000 miles

Well, before my car wouldn't start I had let the gas tank fall below 1/4 tank, and then that night the temperature dropped significantly. And then it wouldn't start, but for instance, last night i had a full tank, and it was having troubles starting on hills again! Days after the de-freezer had done its duty.

Answer 1

Hang on - how are you getting water in the fuel lines? You say wont start on hills, so its starts ok everywhere else? So the only thing that changes is the orientation of your fuel tank right.

If you always have a 'full tank' of gas then i think your pump is the issue. But pumps dont just fail on hills and you would see other symptoms like slow acceleration and lack of power..
When pumps fail they fail gradually and even start working again. Consequently they are a difficult diagnosis and quite difficult/expensive to change.

The 'water in your fuel line' needs a bit of explanation.

edit: what is de-freezer?..
are you driving a diesel or gasoline vehicle?
have you added something to the fuel?

You should also check your fuel pump relay since these can fail or go sticky which will essentially turn off your fuel pump.

Answer 2

Older cars had external fuel pumps usually bolted to the engine block or some electric models on the firewall or frame. Newer cars require the removal of the fuel tank to replace the pump as it is located inside the tank. Someones sick joke or more dollars to the repair shops. Seriously, dont bother with a used one. You only want to change it once.

Answer 3

low gas can cuase that problem, not reahing fuel pump, if your fuel pump in tank you have keep full.. specially on hils where the fuel can't reach pump maybe park facing down hill?
