Chevy Trucks, Blazers, S10 pickup and the like will vapor lock ecspecially the 2000 models. Do not tighten the gas cap past 1 click. There is a tube that runs from the top of the tank down and this gets hot and collapses or burns in half. We just bought a reinforced rubber tube cut it to lengh and use it instead of part and it's worked grat for 2 years so far.

Spray the intake with carb cleaner to find the vacuum leak. Check where the EGR mounts and the throttle body gasket sense you had both off.

That eliminates the crankshaft and camshaft position sensors. Have you checked the fuel injector itself for an open winding or stuck valve plunger? There should not be a steady 12 volts to the injector--if good injector, it would be spraying fuel steadily into the throttle body. But at least the engine should try to run if poorly. Take the injector out, dry it off with air, and intermittently apply 12 volts to one terminal while grounding the other. You should hear a click from inside every time you touch 12 volts. If not, replace it. If it does, it may be plugged with debris. Try blowing through it in reverse with compressed air.

Before you start self repairing, you really should by a manual with proper diagrams to prevent heading in wrong directions.
The PCM doesnt control injector POWER. It controls injector GROUND. The POWER comes from the ignition switch and goes thru a fuse in teh fusebox probably marked ECM1 or ECMa. If you have power at both sides of that fuse with the ignition key in the ON position, then you have a broken wire between the fuse and the TBI. If you have no power to that fuse, you may have a broken wire, blown fuse, or defective ignition switch.
