Question about 2005 Chrysler Town & Country
The miles to empty reader says like 200 some miles to empty and gauge says around half tank.Runs out of gas could it be the fuel pump?
No. Your fuel tank level sensor need to be re calibrated/replaced as it might be stuck in the half tank position. To check this the tank must be as empty as possible, definitely under half tank. Let somebody assist you in the following manner. Go to the filling station switch of the engine but not the electrical power, thus not disabling the fuel gauge from functioning. Let the other person start refueling the vehicle with more or less a gallon at a time. Check the fuel gauge carefully. If it is stuck it will not move until the fuel in the tank start to exceed the half tank quantity. There after it will rise proportionally with the fuel added.
If the calibration is out to such an extent in that half indicated by the gauge means really an empty tank check it as follows. Use the other person again and same method as above. Start filling up. This time the gauge will immediately start moving with each gallon added. Continue till the gauge indicate full and take note of the fuel quantity added. Continue filling up to the point before overflowing the tank. If a lot of fuel (gallons) could be added,the sensor is stuck in the lower part of the tank and also require recalibration /replacement.

If your fuel gauge is showing you in accurate readings this is normal to all vehicles that are not used to fill-up gas full regularly but sometimes the cause of the inacuracy is due to faulty float valve in the gas tank you need to replace it

Has Neon do same, I ran fuel at low level, on hot day, ran engine until it started to act up & threw a fuel pressure gauge on it. Was at approx 5 psi. Cold next morning, 48-50 psi. Always hot day about 30-40 miles into work in morning, o.k. Sit in hot sun all day & would happen 3-4 times on way home. Sit and let cool, 20 minutes or so & go again for a while. Cool day, no problem. Change pump I would.

the fuel gauge sending unit in the gas tank is a mechanical part, but you may have an electrical problem. the needle is moved by an electrical signal. you can check the wires coming out of the back of the gauge, one will run to a chassis ground. make sure that wire has a good connection to ground, first because it won't work right without it and second because it's lots easier than the next thing you will have to do if that doesn't make an improvement. if you see no difference after checking the ground then you need to drop the tank and replace the fuel level sending unit. you will have to remove the fuel pump to get to it so you might want to replace it while you have it out, that's your call. your vehicle is new enough that the decision would be more based on miles than age. hope that helps

SOURCE: WHEN FUEL GUAGE REACHES HALF
from what you are describing you have two(2) different problems
1- the wacky gauge- its acting like a grounding issue- wires are crushed/smashed on tank connector
2- not filling - venting issue- vent line to top of tank pinched
3 solution- run tank down to 1/4 or less and DROP tank down to inspect wires and hoses- sounds like at some point in time the tank took a hit and wedged itself upwards against the underside,pinched the vent line so there is too much pressure in tank and also crushing the wires/plug causing the erratic readings(worse with less weight as the tank moves more)
if unsure of how to do this- you can get a manual such as a HAYES book at auto parts story- good luck
