Listen near the gas filler tube. There's a Schrader valve on the fuel rail, (near the top of the engine, an aluminum tube with a fitting similar to a bicycle tire tube), where you can attach a pressure guage. Usually 40 to 50 psi should be measured there.
If you have good voltage and ground at the fuel pump, and no fuel pump action. Do you have proper fuel pressure? Any fuel pressure? I've seen pumps that would run, but, wouldn't make good fuel pressure. Testing is always a good idea, if you suspect a problem.
If you can raise your car up so that you can get underneath it and listen to the gas tank wherever it is located if you hear a buzzing sound that means your pump is working if not you probably need a new one
SOURCE: FUEL PUMP PRESSURE
Fuel pressure should be around 40-44 PSI at idle, if u replace the pump the correct pump has preset pressure, if the pressure is to high then the regulator may be stuck, it is near the injectors on the fuel supplu rail.

well the pump is in the fuel tank and it depends if the tank is full or not if it is its very heavy and you will need a jack and 1 other person to help you there are two fuel lines to unhook and the electrical connector. When replacing it replace the entire fuel pump/sending unit and the electrical harness or you will end up having more problems also spend the extra 15$ and replace the fuel filter

SOURCE: Chevrolet captiva 2.0 lt poor mpg captiva has
I also have a Chevy Captiva 2L Diesel but with the auto box. The MPG on that one is abysmally bad! I bought it a few weeks ago with just under 30K miles on the clock (2007 model), and it returns around 230 miles on a full tank! That's around 17 MPG and probably on par with a Hummer!!
I was expecting the auto box to be less efficient than the manual of course but not to consume twice as much. Anyone out there with any ideas as to why this could be? I was actually already checking under the car to see if it loses fuel... We live in the suburbs and our trips can be considered a mix of urban and extra urban (they are admittedly on the short side and from a cold winter start; still, this doesn't justify the extremely low MPG). The car seems adequately powered for its weight and considering the small'ish engine and auto box.
Thanks!
