5Th injector / Cold start valve only spraying 1 second - Rough start from Cold

Ive read that it should spray from 1 to 8 sec and some say from 3 to 6 sec.

Mines spraying 1 sec when 100% cold.

How can that be ?

Could be right as the outside temperature is not that cold at the moment. I've unplugged mine so not using one at all as my injectors leak and the car starts fine without it.
Are you having cold start problems?
