The 2001 model year was the last year for the Magneti Morellie EFI system. So the newest systems out there are already 14 years old. So for 14 years the pumps have been sitting in fuel, the o rings, rubber hoses and check valves have also been dealing with fuel. Fuel that in most cases contains 10% ethanol which
Dries out rubber components
Absorbs water
Lack of lubrication properties
Fuel injection relies on:
Clean fuel
Proper fuel pressure
Lubricated components
So fuel becomes contaminated by rust and pealing fuel tank liners and even bits and pieces of rubber components coming apart. That would be o-rings and the interior of the fuel supply lines. The fuel sock may let some smaller stuff into the pump and on occasion the fuel sock will disintegrate and large chunks of junk will get into the pump.
Clean the system by adding a 1/2 can of Seafoam into 5 fresh gallons of gas: it cleans very well and also lubricates. If you see some improvement, you know you are on the right track; rinse and repeat.
Then add a couple of ounces of MMO every couple of refills as a maintenance procedure to keep things clean and lubricated. Add some fuel stabilizer/conditioner like Star Tron after each ride.
Clean the IAC port as well and check fuel pressure to make sure the pump is delivering as it should.
You can wiggle wires, spray coil and wires with water, etc. until the cows come home but if the basic fuel delivery system is not working properly, you will not find the problem. JMHO.
