If you align the flat surface on the front of the distributor with the back side of the upper plenum it will be very close.. Many of the distributors had the white line on the base of the distributor. good luck

How do I reset distributor on 98 chevy k1500 4x4 5.0

To reset the dist. you need to put #1 cylinder on top dead center and turn the oil pump shaft so the dist shaft will seat in the oil pump shaft, when you do this be sure the rotor is pointing to #1 spark plug in the dist. cap. Then replace the hold down bolt to the dist. and just snug it down.
When you put #1 cylinder on top dead center you should be able to look at the timing mark and it should be on zero. Once you get the truck started then you can recheck the timing and tighten down the dist. bolt. Hope this helps.

Chevy timing

cam or spark? timing?

my wild guess, is spark.

its in the FSM book

at at , every day, 24/7

7.4 L liters.

there are 2 systems used, in 97

DIS (no distributor) DIS means, (distributor-less, Ignition systems)


Dizzy engines. with Distrib.

what is yours, the DIS has no timing, its FIXED.

here are the steps on Dizzy

course is first , HV wires set to correct firing order


  1. Remove the No. 1 cylinder spark plug.

  2. Turn the engine using a socket wrench on the large bolt on the front of the crankshaft pulley. Place a finger near the No. 1 spark plug hole and turn the crankshaft until the piston reaches Top Dead Center (TDC). As the engine approaches TDC, you will feel air being expelled by the No. 1 cylinder. If the position is not being met, turn the engine another full turn (360 degree). Once the engine\'s position is correct, install the spark plug.

  3. Align the pre-drilled indent hole in the distributor driven gear with the white painted alignment line on the lower portion of the shaft housing.

  4. Using a long screwdriver, align the oil pump drive shaft in the engine in the mating drive tab in the distributor.

  5. Install the distributor in the engine.

  6. When the distributor is fully seated, the rotor segment should be aligned with the pointer cast in the distributor base. The pointer will have a "6" or "8" cast into it indicating a 6 or 8-cylinder engine. If the rotor segment is not within a few degrees of the pointer, the distributor gear may be off a tooth or more. If this is the case repeat the process until the rotor aligns with the pointer.

  7. Install the cap and fasten the mounting screws.

  8. Install the hold-down clamp and bolt, then tighten the bolt to 20 ft. lbs. (27 Nm).

  9. Engage the electrical connections and the spark plug wires.

fine tuning with timing light is next.

HEI Systems

  1. Start the engine and allow it to reach operating temperature. Stop the engine and connect the timing light to the No. 1 (left front) spark plug wire, at the plug or at the distributor cap. You can also use the No. 6 wire, if it is more convenient. Numbering is illustrated in this section.

Do not pierce the plug wire insulation with HEI; it will cause a miss. The best method is an inductive pickup timing light.

  1. Clean off the timing marks and mark the pulley or damper notch and timing scale with white chalk.

  2. Disconnect and plug the vacuum line at the distributor on models with a carburetor. This is done to prevent any distributor vacuum advance. On fuel injected models, disengage the timing connector which comes out of the harness conduit next to the distributor, this will put the system in the bypass mode. Check the under hood emission sticker for any other hoses or wires which may need to be disconnected.

  3. Start the engine and adjust the idle speed to that specified on the Underhood Emissions label. With automatic transmission, set the specified idle speed in Park. It will be too high, since it is normally (in most cases) adjusted in Drive. You can disconnect the idle solenoid, if any, to get the speed down. Otherwise, adjust the idle speed screw.

The tachometer connects to the TACH terminal on the distributor and to a ground on models with a carburetor. On models with fuel injection, the tachometer connects to the TACH terminal on the ignition coil. Some tachometers must connect to the TACH terminal and to the positive battery terminal. Some tachometers won\'t work with HEI.


  1. Aim the timing light at the pointer marks. Be careful not to touch the fan, because it may appear to be standing still. If the pulley or damper notch isn\'t aligned with the proper timing mark (see the Underhood Emissions label), the timing will have to be adjusted.

TDC or Top Dead Center corresponds to 0degB, or BTDC, or Before Top Dead Center may be shown as BEFORE. A, or ATDC, or After Top Dead Center may be shown as AFTER.

  1. Loosen the distributor base clamp locknut. You can buy trick wrenches which make this task a lot easier.

  2. Turn the distributor slowly to adjust the timing, holding it by the body and not the cap. Turn the distributor in the direction of rotor rotation to retard, and against the direction of rotation to advance.

  3. Tighten the locknut. Check the timing again, in case the distributor moved slightly as you tightened it.

  4. Reinstall the distributor vacuum line or the timing connector. Correct the idle speed.

  5. Stop the engine and disconnect the timing light.

I have replaced ECM,spark plugs,fuel injectors, distributor, the cap rotor button, and it still want start please help!

well the timing on blazers are very hard to set. first there is 2 marks on the harmonic blancer. you need to mark the second mark with white paint. pull number 1 spark plug and turn the motor by hand and feel air coming out of the spark plug hole. there is 2 top dead center (1 is for the exhaust the is 180 out of timing and 2 is the intake at top dead center that is the one you want. if you take off the rotor from the distributor you will see a number 6 that has to be line up with number 1 on the distributor cap. why did he take the distributor out

How do you set the distributor timing on a s10 4.3l

1st look under the hood, and read the veci label for timing instructions, then take a piece of white chalk or white paint , and mark the line that is on the harmonic balancer, then hook up a timing light to the positive and negative cables on your battery, red for positive, and black for negative, then hook the clip or adapter of the timing light to the # 1 spark plug wire, start vehicle, and loosen bolt at bottom of distributor, and turn the distibutor to where the white mark on the harmonic balancer will line up with the timing marks for that vehichle, be sure to look under the hood to refer by what the manufactures timing is for your S-10, after you have the timing marks lined up, then retighten the bolt at the bottom of the distributor, and then check your timing for accuracy, if the timing moved while you tightened down the distributor, you will have to re loosen the bolt and re adust the timing to it's correctness, sometimes , it helps when you have 2 people to do this, 1 can watch the timing marks and hold the timing light, and the other can loosen, and tighten the bolt , while both is communicating to each other in order to get the timing right.

Turns over but dont start. 98 chevy blazer

First verify if you have spark using a tester,then verify you have fuel
now verify timing heres how;

To get #1 compression remove plug and put your finger in the hole and have someone crank the engine until you feel your finger being pushed off by the air pressure. Now line up the timing mark.

Rotate the number 1 cylinder to Top Dead Center (TDC) of the compression stroke.

Align white paint mark on the bottom stem of the distributor, and the pre-drilled indent hole in the bottom of the gear (3).
Notice: The ignition system distributor driven gear and rotor may be installed in multiple positions. In order to avoid mistakes, mark the distributor on the following components in order to ensure the same mounting position upon reassembly:

• The distributor driven gear

• The distributor shaft

• The rotor holes

Installing the driven gear 180 degrees out of alignment, or locating the rotor in the wrong holes, will cause a no-start condition. Premature engine wear or damage may result.

Notice: Installing the driven gear 180 degrees out of alignment, or locating the distributor rotor in the wrong holes, may cause a no-start condition. Premature engine wear and damage may result.

With the gear in this position, the rotor segment should be positioned as shown for a V6 engine (1) or V8 engine (2).
- The alignment will not be exact.

- If the driven gear is installed incorrectly, the dimple will be approximately 180 degrees opposite of the rotor segment when it is installed in the distributor.

Using a long screw driver, align the oil pump drive shaft to the drive tab of the distributor.
Guide the distributor into the engine. Ensure that the spark plug towers are perpendicular to the centerline of the engine.

Once the distributor is fully seated, the rotor segment should be aligned with the pointer cast into the distributor base.
- This pointer may have a 6 cast into it, indicating that the distributor is to be used on a 6 cylinder engine or a 8 cast into it, indicating that the distributor is to be used on a 8 cylinder engine.

- If the rotor segment does not come within a few degrees of the pointer, the gear mesh between the distributor and the camshaft may be off a tooth or more.

- If this is the case, repeat the procedure again in order to achieve proper alignment.

Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.

Install the distributor mounting clamp.

Tighten the distributor clamp bolt to 25 N·m (18 lb ft).

Install the distributor cap.
Install two NEW distributor cap screws.

Tighten the screws to 2.4 N·m (21 lb in).

Install the electrical connector to the distributor.
Install the spark plug wires to the distributor cap. Refer to Spark Plug Wire Harness Replacement
Important: If the Malfunction Indicator lamp is turned on after installing the distributor, and a DTC P1345 is found, the distributor has been installed incorrectly.
Repeat Installation Procedure 2 for proper distributor installation 
hope this helps

How to remover the distrbutor with out getting it

Onced the distributor is removed it will be out of time for its not there no longer. I know what you really mean so start with this. Get a small artist paint brush and some white paint. This works the best. Now clean all areas of the base of the distributor and the mounting area the distributor goes into. Now etched the distributor and the mounting area at the same place. Now brush some of the white paint on the scribed marks and wipe off the paint. The scribed mark should hgold the white paint leaving a good indicator for your marking. Next remove the distributor car. Have a digital camera? Take a photo of the distributor with the cap off. The rotor will have to be at the same location upon re installing the distributor.. If you do not have a camera, mark the base of the distributor were the rotors terminal end is. The position taken out must be returned to the same spot when installing.

Where is the timing mark on the camshaft for replacing a timing belt on a 1997 Toyota Camry 4 cylinder? I can find the hole in the sprocket but there is no mark on the bearing at the 12 o'clock or 1...

The mark on the bearing cap is actually an indentation. It is very difficult to see if the area is dirty. I usually roll the engine over till the area of the mark is between the spokes of the cam gear. Then I clean off the area and take white out and paint the mark. Then roll the engine over til the marks on the crank line up. Tehn using a mirror you should be able to see the white out through the hole in the cam gear.
