It is certainly in no way too late to get a baby to latch. Some babies latch for the first time months after birth- It's not too late!
How is your engorgement now? When the breast is engorged or even very full, it is harder for a baby to latch. One solution is to pump just before offering the breast, but the drawback to that is that the pump may pull fluid into the areola creating or exacerbating the situation of a swollen areola baby cannot latch onto.

How many times is baby being fed each day, how much each feeding, and how? "Nipple confusion" usually means baby is getting so much to eat via the bottle that they have no interest in nursing, or the bottle is being given in such a way that the milk flows into them and they make little or no effort to get the milk as they must at the breast. Yes you want your baby to be fed enough, but it is very important to take the steps necessary to prevent overfeeding. This may mean using a cup, syringe or spoon to supplement, or using paced bottle feeding.
If you are unable to get baby to latch soon, as in, the next day or two, for most feedings, then you almost certainly need a much, much better pump. A manual pump is entirely inadequate for eping and continued use of only a manual is very likely to result in poor milk production and even possible breast injury. Of course, if it's all you have, keep using it....
