How do you set the timing on a 2000 Chevy blazer (V6)
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?"

The timing on a 2.8 V6 Chevy S10 needs to be set any time the valves, heads, or crankshaft are worked on. The gears of the timing chain and timing sprocket need to be aligned to set initial timing.
