Default Cold start injector

I have a bad warm start. It cranks and only runs with wot. A big blue cloud of gas is coming out after picking up. When it runs, it runs fine.
Can be several things: leaking injectors or cold start injector.
I have seen there is a 5 Amp Fuse behind the DIC which says CINJ/CLU ... can I just pull this to disable the cold start injector ?

You'll probably get more responses if you give more detail. What year, anything you've already done in an attempt to diagnose the problem...

Question is very clear:

5 Amp Fuse behind the DIC which says CINJ/CLU ... can I just pull this to disable the cold start injector ?
Any more functions on this fuse ?

Idk the answer...why don't you just pull it and see if you get a different result cold/hot. I posted what I posted^^^to give a better understanding on how that system works. Over a certain temperature that system does not add any fuel enrichment unless allegedly it's leaking. Perhaps schematic on post #22 can shed some light on troubleshooting... https://www.corvetteforum.com/forums...jectors-2.html
