Vacuum diagram for a 1985 chevy s10 blazer

Deb, all 1985 Chevy Blazers were shipped with a sticker in the engine compartment, which includes a vacuum routing diagram, spark plug gap specification, and firing order. Look around the engine compartment and I'll wager it's still there.

I have a 2001 chevy blazer that is missing i have already replaced the distributor ,cap and rotor button and the plugs and wires what else do i need to check

make sure spark plugs gaps correct for the 4.2 engine gap need to be 0.050 for the 4.3 engine gap need to be 0.060. replace fuel filter and clean fuel injectors. missing problem also caused by weak ignition coil.vacuum leaks around intake manifold look for leaking hoses.if all is good do a compression test engine could have burn out valves.

Changed spark plugs in my 1999 chevy blazer and it wont crank over. Gapped the plugs to specs...should I've also changed the wires, cap & rotor also?

When you go to an auto store and they give sell you spark plugs they should already be gapped to spec. There is no need to adjust the gap. This may be the reason your car will not start. I would try new spark plugs first then wires. Since the vehicle is a 99 it probably could use a tune up (spark plugs, wires, coils, cap, rotor, chassis lube, and transmission fluid check and flush if needed). Also make sure that the engine block ground strap is in good condition and that there is no corrosion covering the ends of the ground strap. The ground strap is typically located near the firewall and is directly attached from the engine block to the frame of the car.

97 blazer cranks but wont start,when does start runs great

Your next step in diagnosis your problem should be to check for spark, you'll have to use a spark tester for this, simply removing a spark plug and looking at it WILL NOT WORK, a spark tester looks similar to a spark plug but it has about a 3/4" gap.

Another thing you should check is the voltage of the battery with a multimeter while cranking the engine, if it drops below 9.6v your computer will turn off and your injectors wont fire and neither will your plugs.
If you don't have a multimeter just try jump starting the vehicle.

Hope this helps
