Im not too educated on cars so excuse my lack of terms. my car just works when it wants to. i always keep a full tank of gas and i keep the oil changed. it just wont turn over it acts like it wants to start but it just wont its like its missing that UMPH to get going..what could it be?

Keep checking the oil level and the transmission fluid level to make sure they stay full, but there should be no oil in the gas tank.
There may be water, however, and it may be brown like oil.
Water will sit in the bottom of the tank and make rust underneath the gasoline, since gasoline floats on water.

Use a multi-grade oil- 5W30, 10W30, or 10W40-whatever the owner's manual or the manufacturer recommends. If on a high mileage car, go with the heavier grade, not 5W30. That may thin out too much for a high mileage car.
Not really any special care for wintertime, except this: to avoid condensation build up in the gas tank, a good idea to keep the gas tank as near to full as possible. If the tank is constantly low you may find water droplets in your tank from condensation.

Just a question. Do you run your car on empty. If so that could be your problem with an empty tank you are sucking all the dirt through the filter and making it plug up. It is better to keep your tank above half full and does not cost any more than to run on empty. All mechanics will tell you to always keep your tank above half full.

Fuel pump in fuel tank is not working burned out gas keeps the fuel pump cool should always keep at least a quarter of tank of gas in vehicle at all times

this problem is caused by a defective fual gauge sending unit inside the gas tank.

the problem is caused by a defective gas gauge sending unit, this part is located inside the gas tank, you must remove the gas tank to replace it.

as far as the gas gage goes you might need to replace the fuel senser thats inside the gas tank if this is to costly you can fill your tank up log how many miles your car goes per tank to help you keep trake of when you need to fill up again

Check/Change Fuel Filter(s), PVC Valve & Emission Hoses
and/or
Gas that sits too long won't fire easily that's why we have to add winterize to our lawn mowers!
Try filling the tank with some high grade fuel cleaner additive. This stuff is like rocket fuel (about $10).
Also add a can of dry gas as you may have a lot of water and water vapor in your system!
Get a couple more cans of starter fluid too. (I always needed at least two to get my diesel running for summer)
Keep spraying and starting (It always took me at least a full can sometimes 2)
When it starts keep the gas pedal down and rev high for a good 5-10 minutes then see if it will idle.
If it still stumbles and falls consider adding another can of fuel system cleaner and/or dry gas.
Don't drain the tank as this usually just makes it worse by letting the bottom sludge stir up.
Never let your gas tank get too low as this will foul up your fuel system and always add fuel cleaner after every oil change (a must for fuel injection and cat. converter care)

Good Luck!

PLEASE RATE THIS!

it might not be the gauge itself. it could also be the sending unit in the tank. this however requires you to remove the tank which is not an easy job. if you have a oil light on but the level is good it could be a loose connection on the sensor or the sensor itself. it is located in the engine block and has only 1 wire with a rubber boot connection. as far as the service 4 wheel drive light it may be that there is a loose connection or that the solenoid that ingages/disingages is faulty. please rate this solution. good luck and thanks.

well # 1 the full gauge when empty is a sign that your fuel pump is bad and that needs to be replaced the part about spitting the gas back out is probrobly a clog between the fuel door and the tank itself or their might be a vapor lock door that might be stuck shut so fuel cant get in im not 100%sure about that but im 100%sure that the fuel guage is the fuel pump being dead.
