Brake line problems
i removed my lspv on my 86 pickup and now I can’t get any solid pressure of brake fluid to through any of the bleed valves on fronts or rears. I’m stuck and i have absolutely so idea of what it can be. Also the master cylinder is brand new

The front and rear brakes are completely isolated systems that's why there are two different lines coming off of the master cylinder so deleting lspv isn't going to cause it. Sounds like you didn't bench bleed the new master cylinder.

I'm fighting rear brakes right now and it making sure your drums are adjusted. And getting all air out of the line. Once the bubbles have stopped flowing from that one go to the drivers rear and repeat. If you didn't touch the fronts don't worry about it as long as you never let the MC go dry. If so the do the same for the fronts. Then properly bleed them and you should be good.

What did you do with the lines from the LSPV ??
It can be one of two things
Bad rebuild
kinked or dirt in the brake lines
Enough mud in the bleeder valves fluid can`t push through . that should be easy to see

Like mudpigg said, look for puddles and Wyoming mentioned plugged bleeders, I've seen it often. Pull one all the way out and make sure it is clear, I clean them out with a small drill bit then blow them out and put them back. if that works for one corner work your way around as you bleed.

If you got fluid to move when you bench bled the master cylinder and you don't have any leaks either your pedal isn't moving the master cylinder or you have a blockage in both lines, or you are doing something wrong. try filling the master cylinder, leave the cap off, open all your bleeders and wait. see if the level goes down in the master cylinder.
