I had a check engine light which when diagnosed turned out to be both a P0456 and P0457 evap leak codes.

The fuel pump had a cracked white nylon looking tube on the top which is indicative of the attached vibrating rigid black line that connects to it causing the fitting to crack. I had the pump replaced and had the line cut and a small rubber hose installed in the line to act as a vibration dampener. This worked for a while but now I'm getting the check engine light again. The repair shop dropped the fuel tank and inspected it inside and out. It seems that Chrysler manufactured a tank with a hard white inner plastic lining that buckles up and places pressure on the fuel pump not allowing the pump to use all of the gas in the tank. Consequently you have to dribble the gas into the tank on fill ups and now it's down to a 7 gallon fill till the tank is completely full. The gas gauge reads OK until it reaches the half way point. It will go from 217 miles till empty to 31 miles till empty at the drop of a hat once it reaches the half a tank mark on the fuel gauge. The fix for this is to replace the fuel tank which I was told would cost approximately $1400. The part number for the new tank ends in the letters "AB" which tells me they had a modification done from the original tank. If you replace the tank with a used one you could be getting the same problem over again. You have to inspect the white plastic liner with a flashlight to be sure the liner is not bulging, but there is no guarantee that this used tank that was manufactured at the same time as your bad tank won't develop the same problem. It took 169,000 miles for this problem to show itself so do yourself a favor and spend the money for a new tank or risk going back and forth with this evap issue and eventually spending more on repairs than it would have originally cost to just replace the gas tank in the first place and be done with it.

We have had this car for only a year and half. We have had to replace the fuel pumps in it not once, but twice. We have had to replace the brakes, the spark plugs, the fuel relay system and the torque converter. We got this car so that we could travel as a family. Now my engine light is on and my gas cap light is on.

Took it to a dealer yesterday and they say that the codes are showing that I have a leak in my gas tank again. The Chrysler Dealership in my town sucks and all they can tell me is trade it in. For once, I have no good credit because of having to pay this piece of crap vehicle and now I can't trade it in. I think that Chrysler needs to pay each of the owners of the Pacifica their loans off so that we can get a car that I know won't break down or cause my family to die in it.
