2007 Jeep Liberty - Not Starting: Our jeep will randomly not start and when you turn the key just one click forward the oil light will stay on so we checked the oil and it was fine but added just a little and it started after about 10 minutes. After that we did not have any problems for weeks and then it did it again so we went and had the oil changed - that seemed to help for a month or so and now it is doing it again only may not start for days - and then it will start and run fine again although we are not driving it. We took it in and they told us they had no idea what was wrong and that we would have to wait until it will not start again and have it towed back to the garage because currently they have no idea what is wrong. Any suggestions??? Thanks!
One click is , lamp test, mode, see operators guide on how to start your car, it tells all this lamp stuff.
Does it crank
if a/t car , you cant push start it so

Sounds like your sending unit sensor - if it was your pump going out, your engine would be history by now. Rule of thumb, if your oil check light ever comes on, it's usually too late to remedy the problem. You have a major issue, but since you've obviousely drove it quite a bit since then and it still hasn't seized up, I'm guessing you're ok...for now. Since you took it to a shop and they said you're ok, I'm assuming they checked your level and visually checked for leaks and found nothing. Either, you've got somethijng partially blocking your pick-up tube for the pump which is in your oil pan, or a electrical issue with the sensor. I would start by having someone check the sensor out and go from there...good luck.

This totally depends on how Much "Hard Driving" that you do. Offroad, 4x4 all the Time, ETC.... If you do I would Change at every 50,000 If not Every 80,000 is OK
SOURCE: Cuts off, but will restart, then cuts off again
Likely, you have a damaged engine bearing. When there is a problem there it will turn oil pressure light on because bearings keep the pressure inside the crankshaft...It may stop as the bearing overheats and binds, then loosens up a bit allowing a re-start when it gets cooler. Battery sounding dead is likely because the engine is locking up and too difficult for starter to turn.
At this point, it is not a do-it -yourself project ...either you need a lower end rebuild or engine replacement.
SOURCE: 2003 Jeep Liberty. Changed oil, running very rough and dies.
Buy some Marvel Mystery oil from Auto Zone and add it to you engine oil. Keep an eye on your engine oil level everyday with the Marvel in there and change the engine oil every 3000 miles. Hope the Marvel will clean out the lifters for you and the rest of the sludge in the engine. Do Not Use Engine Flush!!!! There know to eat the seals and kill engine sensors.
The EGR could also be stuck with carbon build up and may need to be cleaned or replaced. Try doing this, turn your radio off and disconnect the battery for a min, turn the ignition key to the run position and re connect the battery then start the liberty. That should reset the air idle control valve.
Let it idle down and then go for a test drive after it warms up. Good luck and keep me posted, while your at Auto Zone have them scan your liberty for any DTC codes. Be glad to help.

OK, you know that you are loosing coolant somewhere. What you need to do (I can't from here) is carefully look at everything that water passes through till you find evidence of seepage. Check the ground where you park (but remember that coolant will run down and across, dripping somewhere other than exactly where the leak is) Check the chassis after sitting a few hours, under the pump pulley and head/block parting lines..rug on passenger side and heater control valve on hoses going into firewall.but definitely EVERWHERE.
