Question about 1997 Chevrolet Blazer
Find the tan wire with the black stripe. It has a connector where it pops out of the harness near the distributor. if you can't find it look under the heater case in the passenger comp. disconnect it. You can now time your motor. Keep the idle speed down so the centrifugal timing weights don't throw your adjustment off. SHUT OFF the motor before re plugging the EST terminals back together.
HVS system is a different can of worms. It has a crankshaft sensor behind the timing chain cover which must agree with the "distributor" sensor position. I have no experience with this system.
