Pull your valve covers and look at you rocker arms see that none are lose if there isn't any lose then you may have a bad lifter witch once you pull your valve covers you will see rods on the far side of the rocker arms, at the bottom of every rod there is a lifter witch rides on the cam shaft. to fix this you have to tear down the top or the whole motor, good luck

94 4.3 vortec intake egr port clogged

You must have an egr valve for this engine to work.Sounds like you are getting oil blow-by combustion causing carbon in the exhaust which may do due to a faulty crankcase ventilation valve, bad piston rings, etc. Whatever the cause, oil combustion produces the carbon, and you will need to fix that.

It can take 70psi to start a vortec engine cold. It should start on starting fluid tho.
You might want to look at a couple of spark plugs to see if they are in good enough condition to run. The spark could be weak under compression if the plugs are worn.

I have a 1997 GMC Jimmy with a 4.3L Vortec V6. It will turn over but won't start. It's getting fire and fuel. All the dash lights come on when the ignition is turned on and you can hear the fuel...

On the vortec engines they require 56 pounds of fuel pressure to start a few pounds shy of that you have a dead vortec you will need a fuel pressure guage to verify
