I presume it has a dizzy "Yes" well near the firewall directly above the dizzy there should be a plug hanning out of the loom unplug it & set the timing on zero by matching the timing mark on the harmonic balancer & the marks on the timing cover then turn the engine off & plug it back in.
the ecm looks after it after that using info from the knock sensor & so on
CORRECTION: The plug for this vehicle is in the passenger compartment, on the passenger side under the carpet against the fire-wall. It is part of the wiring harness that goes from the engine to the ECM (which is located to the right of and under the glove compartment). It is a tan wire with a black stripe. This disconnects the EST circuit which must be done to properly set the timing. See the WikiAnswer to the question "Where can you find the EST wire on a 92 Chevy Blazer S10 4.3 Vortec?"
