2002 v star 1100 wont rev over 3000 rpms sputters and runs like is not getting fuel


Could be that's exactly the problem. I'd check the fuel filter first, cars with fuel filter problems often only exhibit problems like this by saying they can only go Xmph, and not over. While the filter may not be clogged enough to keep the car from running, a 13 year old car can through condensation develop rust in the tank, which could not only foul the filter, but foul it continuously after replacement. I once solved the problem with my motorhome by introducing a huge cannister filter, with a magnet to trap the rust, and a smaller fine filter just before the carburetor so I could tell the gas was flowing and the big cannister needed replacing if the flow diminished.

Other problems that may cause the same issue are timing problems, though most of those have gone the way of old spark gaps, and timing belts that need adjustment. But, if your car's timing works like the older cars, having the timing retarded or advanced could change the cycle just enough that it doesn't want to run right, the fuel just doesn't get enough time to burn completely, or begins to foul the plugs.

Another more modern problem is the coil, while capable of producing enough spark at low speeds, low rpm and therefore low gasoline consumption, boost the rpm, the speed, and push down on the gas and suddenly there's not enough juice to burn all of the gas, and the car coughs, sputters and behaves like it has no power.

Hope this helps!

I have a 93 K3500 with a 454. Truck was running fine, started no problem, ran great. Driving the other day, turn the corner and the engine quit. Cranked the engine, fired up for 2-3 seconds then quit, ...


Before starting the engine, the fuel pump should only run for a few seconds when the key is first turned, to pressurize the fuel system. Even though the pump appears to be running, you may either have not enough or too much pressure for the engine to keep running (fuel pump or pressure regulator). I think it may just be a coincidence the engine quit while turning a corner, but the gas in your tank may have been so low it sloshed away from what is likely a very old pump, starving it and causing it to failure.

Drain the fuel or when you remove the float bowl bolt (also the main jet), then hold up on the float to keep the needle on the seat so gas won't go everywhere. When you have that brass bowl bolt off, clean it! Use nothing metal on it. Pay close attention to the small hole in the bottom and along the smooth unthreaded part at the other end. Use carb/choke cleaner to blast gum and dirt out of those very small fuel orifices. I recommend installing an inline fuel filter also. A shut off valve is recommended too, that way if the needle in the carb sticks open, the crankcase won't be polluted with gas. Usual symptoms on a clogged lawn mower main jet though, are after pushing primer bulb, engine runs about 3 seconds. Try the brass bolt cleaning and post back if needed.
