The check fuel cap light came on. It says to click the cap but it only clicks once--goes no farther--wasn't built to go farther. Should we replace it? If so, where do you get a better one? Today the service engine light came on--is that due to the check fuel cap? The car only has 88,000 miles and we've only had it for a couple of weeks.

Re: check fuel cap light
Probably just a bad seal in the cap. You can purchase a new one from any auto parts store or dealer. Just make sure they cross-refrence the new cap to your car as diffrent caps have diffrent pressure ratings, and you wanna make sure you get the right one. And yes a faulty cap can cause your check engine light to come on as the fuel is not pressurized properly for the motor. Once the cap is replaced with a new one remove your negative battery terminal for a few moments, then re-connect this will clear you check engine light. If you don't do this you engine light will stay on forever.

Hi there: If the gas cap wasn't on properly then the change in pressure would set off a sensor. Put the cap on right or replace it and if the check engine goes away after a few days that was your problem.
You replaced the cap and it will take quite a few driving cycles for the light to go off if that was the culprit. Try disconnecting the negative battery cable for 5 minutes and that might reset the light.
Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.
99% of the time, the gas cap wasn't tightened properly, or is leaking. Make sure you twist it tight and it clicks a few times. If the "Check Engine" light stays on after a few days, buy a new gas cap. Again it may take a few days to clear.
Did you tighten the cap down ? yes you did you may have to turn till you hear clicking noise, now here how it works one the light goes off and you tighten the cap the fuel cap light wont go out just then and there no it will take a restart or a couple of hours to retest the sytem.more likey the next day. also check to see if the cap seals are torn and there are no nick on the fuel neck
Best not to ignore the check engine light because it also can indicate a serious running problem just as it is indicating a pollution problem now. I don't trust folks that have 'snap' answers for a given problem without any kind of testing (the fuel cap). This problem can be caused by split vent hoses or fuel filler hose, sensors that leak or read incorrectly--the list goes on. Smoke generator tests can help track this down but require intelligent analysis to replace or repair the correct component. Finding someone like this to take the time to be at least fairly sure of a cure before loading the car up with unnecessary parts is a rare find. Good luck!
It sounds like you have air in the Cooling system and the bars leak permanent seal does not help. The sealer creates restrictions through out the water jackets and can cause the thermostat to stick. Replace the radiator cap and run the truck with the radiator cap on the first click and keep an eye on the over flow tank, refill the over flow as needed and make sure you have the heater on the highest setting to work out all the air in the system. Once all the air has worked it's way out of the system, then you can close the radiator cap to the second click to ensure full pressure is built up in your cooling system. Good luck and keep me posted.
ford taurus's are well known for this. the seal on the gas cap goes bad. before you replace the gas cap make sure when you close the gas cap you are turning it at least 5 clicks. if light stays on get a new gas cap. they are easy to install all you need to do is remove the gas cap.remove the gas cap strap. put ******** the new cap, close cap and turn 5 clicks. not clicking 5 time can set a p400 or p401 evap code causing the check enging /ses light to come on.
