2007 Vulcan 900 help

So first got this 2006 Vulcan 900 EFI used it had been sitting saw some rust in bottom tank got it home cleaned tank out best I could cleaned fuel filter replaced fuel pump recently as it just went out replaced it with a Ideal one from Amazon. Usually I could clean fuel filter on it when it started sputtering and it would run good for a while. Now filter is clean and it's still sputtering I don't know if this has anything to do with it but when you remove the red clip and pull fuel line off at the bottom gas starts flowing out. I know it's not supposed to do that unless pump is running. Any help would be greatly appreciated. Thanks

Question How is your battery??

Reset disconnect and reconnect your battery to reset ECU.

Is your battery good??? Voltage?

The shop manual for the 900 states that the fuel filter is integral to the pump and cannot be cleaned, but some owners have reported ignoring that and either tried cleaning the filter or removed the existing one and replaced it with a filter from ebay or other source. It is possible that the existing filter is blocked with foreign matter which cannot be removed by cleaning. Also the Amazon-bought replacement pump may be defective.

The Kawi shop manual for the 900 has been available online and has a series of diagnostic steps for testing the fuel pump, but none that I could find for testing fuel pump pressure. Basic electrical test - make certain that the battery is fully charged (12.8v is specified), connect a voltage tester to the pump leads or terminals. Obviously should be zero volts with the ignition switch off. Presumably the pump should be fully installed. Switch the ignition on and for three seconds the voltage at the fuel pump should be 12.8, then it should drop to zero. Should be able to hear the pump run for the initial three seconds. If the voltage is low or non-existent for the test the manual suggests checking the fuel pump relay.

Thanks guys tried unhooking battery to reset ecu and fuel pump is running for three seconds as soon as turn key on. It is popping in the air filter while your holding throttle steady and when riding it when u let off the throttle constantly back firing I'm stumped here I've Google googled thought about trying to replace the coils see if that would be it. Yeah getting the right voltage at the battery.

Will try that this evening when I get home I have been looking over the manual tryin to figure this out stumps me. Also when it acts up like this sputtering and bogging down air popping through breather had brother behind me on his bike and both pipes on inside will glow orange inside and wasn't like that when it was running normal has the factory pipes on it.

Hey guys know been a while been trying to test things trying figure it out we bought a new fuel pump for it still didn't run no better we been trying to do the coil resistantance test and changed plugs still didn't help bought new boots didn't help so took to dealership to plug up to there computer said it had no active codes but in history had 3 ignition coil codes so bought new could for it from dealership and that actually made it better it responds to throttle better but still spits spitters a little while holding it at steady idle haven't tried riding it yet to see how it acts with a load on it but before when u went from idle to wide open throttle it would die now it's responding good shooting the rpms up pretty quickly just still spitters and spits out exhaust if u hold it at a steady throttle so afraid to try to ride it. Any ideas be greatly appreciated been looking at service manual searching for a answer but really don't know what to look into now.
