SUV won't let me put any fuel in. Spits it right out.

Try adjusting the valve that holds the tank in place, make sure the hose is not kinked when fueling

It sounds like the vent tube on the gas tank may be either plugged, or partially pinched off. Once you start putting gas into it, and have a gallon or two in, does it improve? If the vent is blocked, the only venting you are getting will be around the fill tube you are putting fuel into. Until you get the problem addressed, the only solution is to fill the tank at a reduced rate. Hope this helps.

Is the check engine light on while the engine is running ?
If it is I would start there for clues.
If not, the list of possibilities is long.
You should check the fuel pressure and probably the throttle position sensor resistance. It could have a vac leak too.

check to see if fuel spits out of the hole.

Someone probably changed the fuel pump at one time and may have put the fuel fill hose on wrong or kinked it shut.

WOO stop there is a major recall with the 05 durangos the check valves get stuck they are recalling the gas tanks on thousands of those car. that is a big fire hazard. Go to the dealer I garente ur vehcle is recalled u may have not gotten the notice in the mail yet. Please rate if this helps.

Here is a copy of the dealer recall notice.

2005 (HB) Dodge Durango
NOTE: This recall applies only to the above vehicles built from October 13, 2004
through November 30, 2004 (MDH101300 through 113023).
The fuel tank inlet check valve on about 18,900 of the above vehicles may stick in
the open position. This can cause fuel to spill out of the filler tube when the
vehicle is being refueled. Fuel in the presence of an ignition source can result in a
fire.
The fuel tank inlet check valve must be tested for proper operation. Vehicles with
a sticking check valve must have the fuel tank replaced.

Sound to me like you have water in the bottom of your fuel tank. when you fill it the water is mixed with the gas until it settles. put some gas line antifreeze into the fuel tank, may take several bottles. but this should help. if not you will have to have tank taken off and drained.

Check the Fuel pump with a presure guage.

Had the same problem with by 1998 S10 a couple years ago. Changed fuel filter?? didn't work. Changed the fuel pump?? didn't work. Changed the fuel pressure regulator?? didn't work.

I was about to the end of my rope when I put a timing light on it and it showed firing on cylinders more then once a cycle. Turns out my distributor cap was bad and spark was jumping between contacts. When a spark is spread out over more then one cylinder, it doesn't fire correctly and that is causing it to bog out. Simple and a lot cheaper then all the other fixes I tried. Crank sensor was my next option though.

Have you tried the fuel filter?
