Question about 2000 Chevrolet Blazer

1 Answer

Completed tune up, drove for 2 blocks, engine shut down

I have a 2000 Chevy Blazer 4x4/4.3L. I replaced the spark plugs, plug wires. I removed the steering column connecting rod from the steering gear box to replace the three plugs and wires on the driver side then reattached. Replaced the three plugs and wires on passenger side. Started blazer, had a very nice and smooth idle. Great improvement from prior to replacement. I drove for two blocks(reverse, right turn after 50 feet, straight for 125 feet, left turn, then another 125 feet) the truck died and has not been able to start since. I can crank the engine until the battery dies. I have checked to see if I have spark,yes, check to see if I have fuel,yes. I have since replaced the ignition control module, still cranks but will not start. I have 3/4 tank of gas. I am losing my patience. I start a new job in less than two weeks. I need this vehicle. Please help.

Just having fuel is not enough on this engine, here are the spec's. Even 1 psi out of spec can cause a no start.

No spark to engine 1991 ford pickup


It can be faulty or dirty spark plug itselfd.Also for reference get the fuel level checked.Is the fuel tank is empty or near to empty.
Try cleaning the spark plugs and then see if that is helpin.On some cases the black carbon layer gets collected on the spark plugs and that causes the problem,so cleaning the plugs help.But if its not helping,then spark plug has to be replaced.Spark plugs get power from ignition coil to ignite sparks.If ignitioncoils are faulty then also there will no spark.--------------

A diagram of the flushing of a radiator and block of a chevrolet blazer LS 2000


Theres no such thing as a diagram, here are the draining instructions, hope this helps...
  • 1-Place a large drain pan beneath the radiator drain plug. The drain plug is located on the passenger side at the very bottom of the radiator on the engine side.

  • 2-Make sure the engine is cool. Open the hood of the truck and remove the radiator cap.
  • 3-Loosen the drain plug. On the 2000 Blazer, the drain plug is a wing-nut type of plug. Twist it with your fingers until the coolant begins to drain.

  • *To flush the block, once you have drained the radiator, run the engine for a bit untill the temp gauge goes up to normal, then the coolant will have been evacuated from the block. DO NOT leave the engine on, once it reaches normal temp, (this will happen quick) turn off right away, otherwise you'll be forking out a few hundred $$$ to fix the worped heads.
    4-Tighten the drain plug with your fingers once the coolant has drained fully from the radiator. Remove the drain pan and dispose of the used coolant properly.
    Some service stations will take and recycle your used coolant.
    Hope this helps...

    Ai have a 88 chevy s-10 blazer it stall when i drive a block like it starts to cut out does it need a fuel filter, if so is it under the truck or does it need spark plugs only or does air filter only...


    I suggest a full tune up.

    1. Air filter.
    2. Fuel filter, carbureted engine filter is located inside the line fitting where it attaches to the carburetor. Fuel injected engine filter is located in-line under the truck near the tank.
    3. Oil and filter.
    4. Spark plugs and wires.
    5. Distributor cap and rotor if applicable.
    6. PCV valve.

    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.

    2000 chevy blazer starts sometimes and sometimes not. replaced starter, spark plugs and wires and fuel pump. still same problem. could it be the mass air flow meter? Jackie


    Check for spark by removing one of the plug wires from a spark plug and installing one of your old plugs in the removed wire (leave the other end of the wire attached to the cap). Rest the exposed plug on an under-hood surface that will provide a sufficient ground and have some one turn over the engine. You should se a strong blue spark. We have seen some intermittent coil problems on your generation Blazer that would explain a lack of spark. Good luck!
