SOURCE: No timeing marks on a chevy 383 stroker engine

you could bring it up on tdc on comp stroke and make your own mark on crank pulley and block then at least you know where tdc is and google some 383's that have close to same equip as you and see what degree they are running or just play with it and see how it runs .

SOURCE: I bought a '94 chevy p.u. project truck

Have you checked the temp sender? If the computer does not know the engine is cold it won't put enough fuel into the mixture to get it started.
If after starting it by priming, if you can get it to run, I'd look there.
Also on most systems the crank sensor will play a part in there as well...If the computer does not see a signal from there it will often shut down the fuel pulses to the injectors.
If simple testing does not show you anything, have a code test done and see at least which systems are showing faults and work from there. Chiltons and Haynes list individual component tests you can do to isolate a single component.

SOURCE: set timing on 87 chevy truck 7.4 tbi

After checking this out, i found that this truck has a throttle position sensor. Not sure if there is a timing mark at all. I believe it is set by the ECM (computer) via the TPS

1995 chevy 1500, 4.3 vortec engine was replaced to 5.7 and computer. Everything else stayed the same. when pushed to passing gear at low speed, engine accelerates and blows/pops through TBI carb.

Check and make sure the distributer is advancing the timing. If you have a timing light mark the balancer with chalk or a paint stick. When you rev the engine the mark should move. If not you have a bad distributer.

Setting timing marks to get vehicle to start after engine overhaul

Timing marks setting Corolla 4A-FE.
Align the notch on the crankshaft pulley with the "0" mark on the timing belt lower cover.

With the crankshaft pulley being aligned with the 0 mark on the timing belt cover, the hole on the camshaft sprocket should exactly be in front of the notch of camshaft bracket.

Hope that works.

How to set timing

  • Locate the timing scale located beside the crankshaft pulley. The "T" or "0" represents Top Dead Center. The plate is scaled in one or two degree increments and should have the correct timing marked for your particular car. If not you will have to count to the correct degrees, which will be on a printed lable somewhere on the vehicle, under the hood.locate the notch on the balancer or the crankshaft pulley then mark it with chalk ot a white paint marker so it will be visible under the timing light. start the engine and let it warm up to normal operating temperature then shut it off. turn off all lights and other electrical loads.With the engine off, connect the pick-up lead to the number one spark plug wire. connect the timing light power leads according to manufacturer's instructions.Start the engine and point the timing light at the timing mark by the crankshaft pulley. Take note as to where the timing notch is lining up with the timing scale.If the notch is not lining up, you have to loosen the hold down nut or bolt on the distributor. Turn the distributor until the notch lines up with the timing scale.Re-tighten the hold down nut or bolt and recheck the timing, making sure the marks didn't shift. turn of engine and disconnect the timing light.

    Replaced distributor on my 1988 chevy c3500 pick up. 5.7 liter engine w/ tbi. not sure how to set timing? is advance going to change the value? looking for timing setting and procedure to reach setting...

    Hi, I have pasted the procedure below. Your spec is 0 degrees (right at TDC).


    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 underhood 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.

    WARNING Never ground the HEI TACH terminal; serious system damage will result.

    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 0°B, 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 ******, 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.

      1. Tighten adjusting bolt to hold tensioner in released position.
    1. Align crankshaft so number one piston is at TDC (top dead center) with crankshaft key pointing straight up and circle on crankshaft sprocket (6306) aligned with notch in engine front cover (6019) .
    1. Align triangle on camshaft sprocket with triangle on inner timing belt cover.
    1. Align diamond on oil pump sprocket with diamond on inner timing belt cover.

    I have a c3500 chevy silverado, 7.4 litre engine and the specifications for tuning is not under the hood. I do not know what timing marks should be. Please help. The distributor was removed and repleced to...

    Is this tbi? I'll have to look it up but it should be set at zero degrees with the timing connector unplugged, I think. The timing connector is under the plastic relay cover on the passenger side firewall. It is a single wire plug that the wire is tan with a black tracer. With this unplugged you set the timing mark to the large gap on the timing tab.

    How to set the timeing on 91 geo storm

    The timing marks are located near the top of the crankshaft pulley on the plastic timing belt cover. There is a notch in the pulley to mark TDC (Top Dead Center)
    Align the notch with the 0 mark on the plastic cover to set your base timing.
    Ground the proper circuit on the ALDL connecter located under the dashboard somewhere under the steering wheel. Check the manual for the proper circuit to ground.
    With the engine warm and the circuit grounded. Set the proper timing. Un-ground the circuit and you are done.
