Question lang sa SR20 (or any efi car)

Pag cold start ko (meaning the car has been sitting for over 12 hrs or so) hard starting yung car, parang naubusan ng gas.

But if I leave the key sa "ON" for a few secs and depress the accelerator a couple of times, it starts fine.

After that, kahit ilang beses ko istart, one-click na sya.

Baket parang nawawala yung fuel sa fuel line pag coldstart and kailangan pa sya i-prime?

Chineck na fuel pressure ok naman

BTW, sa mga sumagot na sa ibang board, thanks, dont repost na hehe
