Probably too easy, but hows the fuel filter. And the fuel pressure

Well a new pump should have the right pressure, but they use the same pump for V8 powered chevy's too.
This is why they have to regulate the fuel through a fuel regulator, which could also be worn out.

My 87 had a idle adjustment screw. Look right in from the front where the cable is. Mine had a hole in the throtle body with an adjustment screw. I had a problem once inside my distribitor. Under the rotor there is a star plate with a magnet pick up. My truck wouldn't start. I changed everything. I saw that thet star plate had some light rust on it. I took it out and hit it on my wire wheel to clean it up and put it back in. The truck started rite up. I'm not saying that is your problem but its worth a try.
