Chevy timing


cam or spark? timing?

my wild guess, is spark.

its in the FSM book

at at alldata.com , every day, 24/7

7.4 L liters.

there are 2 systems used, in 97

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

or

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

1-8-4-3-6-5-7



  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.

4:



  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.

Trying to hook a tachometer to a 93 gmc seirra 1500 350 were does the green wire go?


The "Green" wire from the tachometer should be attached to the negative side of the ignition coil only, and usually (but not always) it is a black wire with a white stripe or it is a solid white wire that will come off from the negative side of the ignition coil and often has a tab on the wire that says "Test" or "Tach" and the wire ends with an open black connector that is used for connecting a diagnostic device or tachometer for diagnostic purposes, and this is the wire that the green wire from the after-market tachometer should attach to. The "Red" wire should be attached to an "ignition" source connection on the fuse panel and have battery power when the key is in the "Run" position only, the "Yellow" or "White" wire should be connected to the "LPS" source on the fuse panel, and the "Black" wire should be connected to a good ground source and if the tachometer is not properly grounded then you will get a primary voltage shock from the ignition coil every time that you touch something metal inside of the vehicle. Let me know if you require any further assistance.

We've replaced the distributor cap and rotor in our 1985 Chevy C10 305 V8 and still have to fire TO the plugs. It won't start


This is a one piece distributor. It has the coil and pickup sensor all built in. Check and see if you have 12 volts on the large red wire that plugs into the cap while the key is on. (The other wire is for a tachometer if you have one). If you have power and there is no spark from your ignition wires, your pickup module is bad in the distributer. Very rarely have I seen a failed coil.

1990 chevy lumina apv 3.1 liter


There is no RPM pickup switch on a 3.1L MPFI. The RPMs are derived from the igntion module, its a white wire on the 6 or 7 prong clip. It uses input from resolution of crank sensor to determine engine RPM. what is your problem?
