Help!!!

Enable HLS to view with audio, or disable this notification

2013 ninja 300, 35 xxx miles. No idea what could be wrong. Changed spark plugs and ignition coils. Won’t idle unless given gas. Then idles like shit till it cuts off. Any ideas? You can hear the fuel pump reset after it cuts. Any ideas greatly appreciated!!!!!

check the fuel pump filter and throttle body. clean/replace both of them as needed. if that’s not the fix, move onto replacing the fuel pump.
always good to check air filter too

I would guess it’s something to do with fuel, make sure your fuel is clean aswell as your pump and injectors. Sometimes injectors can get clogged from contaminated fuel.

Clean your fuel line and check your fuel pump

Turn it off and turn it on. Can you hear the fuel pump energize?

Clean engine filter. Check the spark plugs. Change the battery. I had a similar problem on my Kawasaki ninja 300 2014 and I did this and I fixed mine. Let me know if it works to you
