Im no pro, but heres my "help" haha
Ok first step: Clean all fuel filters (Swirl, and Fuel pump) out with brake cleaner to get all dirt out then use compressed air to LIGHTLY dry it out.
2. Check fuel pressure regulator, make sure it's in the right spec for psi.
3. Check for any air leaks or any unhooked hoses or wires.
4. Clean injector and throttle body, also make sure if you have the "Choke" blocked off that the plunger is sealing in the throttle body properly.
5. If none of hat works chances are your gonna have to get the fuel pump or mess with your tps... It sounds like its running lean.
Hope you figure it out!

Had the same problem it was the swirl bowl filter clogged, doing it again... Got spots of gray looking jelly in my ims gas tank. Not sure if the fuel lines are melting from the inside or sticker glue soaking into the tank. I'm using vp 94 non ethanol. Hopefully It'll be an easy fix for ya.

I kept the swirl bowl , sucks cause the filters are expensive, but it needs to be filtered to the correct micron rating cause it is fuel injected, some guys get rid of it and put an inline filter on, I think earls makes one you can buy of summit racing
