I HAVE 4 2009 4000 MULES I MAINTAIN AT WORK. ALL OF THEM HAVE THE SAME PROBLEM-THEY CONSTANTLY STALL. THEY START FINE BUT STALL AFTER YOU COME TO A STOP OR IF YOU REV THE ENG THEY STALL. THEY RUN FINE IF YOU CAN GET GOING. I'VE CHANGED PLUGS,AIR FILTER, ADJUSTED THE VALVES. I DON'T HAVE A WAY TO CHECK FUEL PRESSURE. THE DEALER SAYS IT SHOULD BE 41-46 PSI AT IDLE. I'VE CLEANED THE SCREEN ON THE FUEL PUMP AND EVEN TRIED REMOVING IT ON ONE-I PUT IT BACK AFTER A DAY TO SEE IF IT MADE A DIFFERENCE. THEY SAID WITH THE KEY ON FOR 3 SECONDS I SHOULD GET 1.7OZ OR MORE FUEL OUT OF THE LINE. I GET 2.5-3OZ ON ALL 4 OF THEM. THE DEALER SAYS THATS FINE AND MY PUMP IS PROBABLY NOT THE PROBLEM. ALL THEY TELL ME IS ETHYNOL IN THE GAS IS THE PROBLEM. IF ANY OF YOU HAD THIS PROBLEM AND FIGURED IT OUT I WOULD REALLY APPRECIATE SOME HELP.---THANK YOU

The EPA and there ETHYNOL is going to cause a lot of problems with rubber parts in the engines fuel systems and obama has signed into law just recently to make it even worse. Your dealer could have a good point but it takes more then a few years for the problems to show up unless they used real poor quality rubber in your rig.
Put a fuel pressure gauge on the engine and watch it as you drive it around and take note on what happens with the pressure when it stalls. if there is no change then it may be electrical....

Strange that all 4 of them have the exact same problem. This might be dumb, but could they all possibly have water in the gas? Because alcohol is hygroscopic (draws moisture), and because of increased alcohol in fuel these days (10-15% all the time, not just in winter like it used to be, at least around here), water in the fuel is a more common problem than it used to be. Maybe wouldn't be a bad idea to use a "dry gas" product all the time. This alcohol content also doesn't always agree with the original factory carb jetting (which didn't necessarily account for that alcohol content), so that may also be an issue as well.

The more alcohol in the fuel the bigger the jet is needed to fuel the engine and that means less fuel economy. The EPA/CARB keeps changing the fuel consumption requirements of cars and trucks and then changes the fuel to include more alcohol. It is like changing the rules of a game. Alcohol is a high octane fuel and works well in the drag cars we built but it takes a huge jet to feed the engine. A 100% alcohol engine would consume 50% to 75% more fuel on a run then a car with 110 to 120 octane fuel. Yes it does attract more water as well and it is very hard on rubber.....
