The easiest way to verify a faulty water pump is by the "weep hole" located on the top of the pump's housing. Next you can verify flow in the cooling system by (be sure the engine is cool)running the engine at idle with the rad cap open. You want to stimulate some cross flow of coolant across the opening at the cap by gently squeezing the upper hose down from the thermostat outlet, after each squeeze you will should see surge and recession of coolant and flow. If the pump is faulty, the bearing squeals like a banshee, as well as coolant leaks from the weephole, high engine temperatures at idle and speed. If your pump is faulty, chances are you will know it, you should replace it very soon as overheating damage can be devastating.
1.6 geo tracker motor or sidekick would work its all the sme
Check fuses Check bulbs
Because of an electric fault
check the electronic fuel pump harness for shorts at connector ends
It is on because the PCM has detected a malfunction, see related questions below.
if you disconnect the o2 sensor cable in the air intake then start the engine you would see the check engine sign turned on in the gauge panel. It is on then the sensor is working if off the the sensor may have problems
Check the vaccum lines to tour EGR valve cracked or loose vaccum lines will cause the air intake to suck too much air causing it to surge.
test flow in and out of heater core it may be plugged or need replacing, if it is not plugged up check temp controls, may be stuck in vent or a/c setting.

The fuel filter is located under the car in front of the gas tank.
My first guess would be that you have a sizable vacuum leak some where... Check to see if you can find any vacuum hoses that have disconnected or that may be cracked or split.
