No air pressure at rail - possible fuel pump, or, just needs pressure added at rail valve

You need to check the fuel press, the test port in on the rail, also run a code test on the ECM/PCM, this checks for trouble codes and also lets you know the computer is working if it tests ok.

Chevy blazer 1998 4-wheel drive - losing power when it's hot (after about 100 miles) once it cools, everything is fine

First thing to check is the fuel pressure and volume. Sounds like a fuel pump (in the tank) problem, but also be sure to check the filter as they can clog on this model. Testing the pressure with a gauge is the only accurate way to know if I am right. Clogged filter will give normal pressure but it will come up slowly. You can probably rent or borrow a pressure gauge from a local auto parts store if you do not have one. There is a fitting on the fuel rail, so you do not have to open up the fuel line to test the pressure.
