NEED Help - Clutch Bleeding Gone Wrong

NEED Help - Clutch Bleeding Gone Wrong
Background:
I just replaced the clutch, pressure plate and flywheel.
When I went to put the slave cylinder back on I had to crack the bleeder open So I could get the push rod depressed to line up the mounting holes.
When I cracked the bleeder it was like a volcano went off. (I read after the fact that the system is always pressurized..??)
Now I can not get the system to hold pressure. The pedal just flaps to the floor.
I read several threads here about how you need to have positive pressure in the system when trying to build it up. So I bought on of those fluid transfer pumps so I could "force" fluid to the slave cylinder. This still isn't working. I can't seem to force the fluid with the pump in the system. If I crack the bleeder and try to pump the system i can barely get any fluid in. It feels like I can not get any fluid past the master cylinder. Yet, if I crack the bleeder with pressure in the system (from the pump, because the clutch pedal doesn't do anything.) I can get fluid out of the bleeder.
My only guess now is the brake master cylinder is bad????
Am I missing something, I've never had any issues like this with any clutch before.

It’s a pain, I always use a pressure bleeder. Position of the bleed port on the slave make it impossible to get the air out efficiently

Seems like I got some pressure in the clutch. It won't pop up to the top all the way but I heard this may be a bad spring.
Now, the car will not start. I used a NAPA flywheel, Clutch and PP. From what I heard it is most likely the crank angle sensor that is suppose to read a signal to start. Apparently it isn't seeing the proper signal to start the car.

Could the flywheel be installed incorrectly? I thought I recall reading something about that affecting the crank position sensor and starting.
@terrasmak what fitting do you use on the Nissan for pressure bleeding? The reservoir cap doesn't tighten down enough for me to get a good seal with an adapter I made (I only use a few pounds of pressure with it....):

I use the motive bleeder with the cap for brakes. Someone just has to hold it the whole time, although I could probably figure out a better way to hold it on.
