Car struggles to start. Runs perfectly fine

[Dmn.Stmb]

Hi guys,
Basically my k24 swapped 99’ ek running a kprov4 would start fine after we did the swap. Slowly it began struggling to start so we put it down to spark plugs which were changed, still struggled. New fuel pump, fixed the issues for like two weeks now it won’t start again. All grounds have been checked and are good, car cranks strong so starter doesn’t SEEM to be it. It typically has a harder time on cold starts, usually when it’s warm it’ll start normally.
Have no idea what it could be!

Have you discussed the issue with your tuner?

No not yet, will definitely reach out to them tho. Does it seem like a tuning issue?

It could be any number of things.
