Need to connect a fuel pressure gauge and see if you are getting sufficient pressure to the tbi

Does it start if you spray starting fluid into the air inlet of the engine? If so the fuel pump has failed.

Check fuel pressure

No. Only Ford products have an inertia switch for the fuel pump. Chances are your fuel pump is too weak or not working at all. Most GM trucks require 65psi of fuel pressure to start, 70psi when cold.
Will it start by using starting fluid sprayed into the intake ?

1994 chevy s10 blazer turns over won start Google Search

I was given a 1994 s10 Chevy Tahoe vortex blazer??????? It's either a S-10 pick-up or it's a Tahoe or a Blazer not all three . So which is it ?

Check for gas or spark problem on the engine. Check that starting fluid does start the car for a few seconds before dying, indicating a fuel delivery problem, like a fuel pump or circuit to it.

If the car won't start with starting fluid sprayed into the intake, then the ignition system may be at fault, or engine timing.

if this happens only in the morning after you start for the first time its the clutch on the fanblade needs replacing

Well, obviously someone didn't tell you the truth because spraying into intake doesn't make the vehicle turn over any better. You have ignition or fuel delivery problem. Start by taking fuel line off at intake and crank engine a couple times catching any gas in a cup or something. If none, then trace fuel line back and under vehicle til you find filter. Should be under driverside midway back on inside of frame. Change this and try test again. If no gas, see if fuel pump is on motor(mechanical pump). Change this and test again. If not on motor then it's in gas tank(electric pump). Most cases the tank has to be lowered to take out pump, careful not to drop, dent or make sparks. Some came with access through the floor so check that first. Normally you can hear an electric pump come on when you turn the key. Good Luck
