Slow cranking can be a couple things. Starter dying. Batteries dying. Bad battery cables and/or battery terminals. Hard starting can be fuel drain back. Fuel supply restriction. Or a bad injection pump. Your fuel pressure is good, though a little more pressure would be better. I like to stay just over return pressure so fuel circulates through the IP keeping the electronics cool at low RPM.
