They gas gauge on my 2006 pacifica touring want go pass 1/4 of a tank I've put a new fuel pump in it what could it be

If I had to make a guess, I'd say your fuel gauge is getting stuck 1/2way. Do you have to fill the tank completely after it dies?
If it's yes, then the gauge needs to be replaced.

It could be the gauge on the dash or the sending unit in the fuel tank is bad. If it is the sending unit ,the gas tank will most likely have to be taken out. And if the dash gauge the dash will have to be taken apart. Diagnosis of Stuck Fuel Gauge Is it Gauge or Sending Unit Here is a video how to test it.

theres two plugs on the fuel pump. one is for pump and one is for gauge if you take pump out of tank and put a volt meter on the two outer prongs in plug then the two inner two of them will read the same when yoou move the level up and down and when you put meter on other two it will change when you move level or the level part of pump isnt working correctly. my old tahoe did that and when it would get to a 1/4 of a tank i knew it was almost out of gas.

Not without knowing where the leak in the vent system is.
It could be anything from the gas cap to a missing hose between the tank and the vapor canister.
The computer vents the gas tank to the vapor canister while you are driving. The code is for a large leak in the system.

there is a level sensor in the fuel tank you need to drop the tank out to change it

I think that your fuel level sending unit inside the fuel tank may be at fault. Because the sending unit is immersed in fuel, and the float arm is constantly moving as the fuel sloshes around inside the tank, the sending unit can eventually wear and send an erratic signal to the instrument cluster. Another type of failure can occur if the sending unit becomes coated with deposits from fuel that will also affect how accurate the sender signal is. Before replacing the sending unit I would try using a fuel injector cleaner that has the additive "Techron" in it to see if this would clean off any accumulated deposits on the sender and restore it to working order. I've had pretty good results using this approach on several vehicles in the past few years and if it doesn't help you're not out much more than the cost of the cleaner. Good luck, hope this helps!

2007 Chrysler Pacifica having intermittent fuel gauge problems. Goes from normal to dead/ low fuel. Has full tank. Also, check engine light is on

you have 2 recalls
pcm update fuel pump replacement
fuel pump module replacement and pcm software

The problem will get worse, to the point that it will leave you stranded, out of gas. The solution is simple but most dealers don't catch it. They try fuel pumps, computer updates, sensors and the problem persists. You can fix this problem yourself and without spending a nickel. Want to know how I know? I've owned two Pacifica's and both have done this. Here's why: The Pacifica has a very unique and poorly designed fuel storage system. It uses what is refered to as a saddle tank. This is so they can use the same tank in both the all wheel drive and the front wheel drive versions. If you look underneath you will see it actually looks like two tanks. The driver side is the fill side and the passenger side is the delivery side. There are actually two fuel pumps, a main pump (pumps gas to the engine) and a equalization pump (pumps fuel from the the fill side to the delivery side of the saddle tank. The problem that you are experiencing carries with it several symptoms; running out of gas when the tank is half full, the gas gauge dropping suddenly at half full, and the inability to pump more gas into the tank without shaking the car back and forth and/or pumping very slowly. This is because of the way the two sending units inside the tank send their signals to the gas gauge and the fact that only when the fill side of the tank is 100% full, can some of the gas flow over the top of the hump to the delivery side tank. You can replace pumps all day long and most likely still have the problem. So what's the fix? It's simple. Underneath the vehicle, inline with the emissions lines going to the gas tank, about middle of the vehicle, there is a small plastic air inlet filter about the size of 50 cent piece mounted to the floor of the vehicle. It is responsible for venting the tanks pressure, allowing fuel to flow into the delivery side tank. It get's full of dirt and debris. Replace it a cost of about $3.50 or just blow it out with compressed air. If you don't want to do it yourself, help those dealers out - point them in the right direction, or else they will be running in circles trying to fix the problem. NOTE: this is only a problem on Pacifica's, not other vehicles. More info on this issue here; http://www.dodgeboard.com/forums/index.php?threads/my-crazy-gas-gauge.6381/

r u sure? sounds like the float is sticking.
