You need to mark in 2 places. With the cap off mark the position of the rotor button on the distributor housing first. Then you need to make a mark on the distributor housing that will line up with a mark on the engine itself.
When you put the distributor back in back the rotor button up before you put it in because the cam gear will turn it ahead as it seats. For example, if the rotor button is at 3 o'clock then back it up to 1 o;clock.
Don't force the distributor down at the end because you can damage the end that drives the oil pump. Fidle and wiggle it as you push and it should line up and drop onto the oil pump. Also DON'T turn the engine over while it's out or you will have to retime the engine. Hope this helps.

The engine should be set on TDC (Top Dead Center) with the distributor cap removed, and there is a mark or notch on the distributor housing that the rotor should be pointing to when the engine is on top dead center. (Look under the distributor cap and find where the number one terminal runs under the distributor cap, and where that position on the distributor cap corresponds with the distributor housing, and it should match up to a mark or a notch on the distributor housing)

This static timing is all that matters and the computer will be able to control the timing as long as the ignition rotor is in that position when the engine is at top dead center.

Then make a mark out on the engine or fire-wall where the ignition rotor is pointing to (Mark#1).

Then un-bolt the distributor and lift it carefully straight up from the engine about three inches, and watch the ignition rotor when you lift up on the distributor and the ignition rotor will turn as you lift up on the distributor, carefully lift the distributor up and as soon as the ignition rotor stops turning (after lifting the distributor up about three inches) then make another mark out on the engine or fire-wall where the ignition rotor is now pointing to (Mark #2), and then lift the distributor straight out and you should now have two separate reference marks for installing the new distributor.

Be sure that the new distributor has a new gasket or seal and that any old gasket material has been thoroughly cleaned.

Then lower the distributor into the engine with the ignition rotor pointing to the second mark (Mark #2) that you made just before removing the distributor.

Continue to carefully lower the distributor back into place with the ignition rotor pointing to the second mark (Mark #2) and as the distributor is lowered back down into the engine the ignition rotor should turn to the first mark that you made (Mark #1) and the distributor should set all the way back down with the ignition rotor pointing at the first mark (Mark #1).

Replace the bolt to the distributor and then align the #1 position on the distributor housing with the ignition rotor and then tighten down the distributor.

How to remove distributor on 1984 monte carlo 305 v8


bring engine to top dead center #1 with the timing marks. remove distributer cap and note position of rotor direction and mark on the distributor housing were the rotor is pointing. also mark the position of the distributor mark to a position on the motor, then unbolt the distributor holding bolt and remove. pull up on the distributor and note which way the rotor moves as you pull the distributor out. again mark where the rotor is pointing when the distributor is out. the reason for the marking of rotor position and distributor position is so when you reassemble you line up the marks to get it into the proper position when the distributor is back in place. then you have to check the timing and set. as far as the pickup coil remove the distributor gear lock pin remove the gear and remove the distributor shaft to replace the coil. reassemble in reverse order.

Want to remove and replace the distributor in my 1997 gmc


1 Remove the plastic cover from the engine block with a wrench, then let the spark plug wires lead you to the distributor. It's at the back of the engine block.


2 Remove the negative cable from the battery at the side of the engine compartment; carefully pull the spark plug wires off the distributor cap so you don't damage them. Use a screwdriver to take off the coil leads from the distributor and the electrical connector at the bottom of the distributor.


3 Loosen the clamps and take off the distributor cap. Mark the parts to align the rotor position to the distributor housing and the housing to the engine block. This will help replace parts correctly during distributor installation.


4 Unbolt the distributor hold-down bolt with a wrench and remove the distributor from the engine.


5 Install the new Sierra distributor, aligning the marks for proper seating in the engine block. When ordering the distributor, give the parts dealer your model, year and engine size. You can order part number A1841639 from Parts Train for a 4.3L engine.


6 Re-install the distributor hold-down bolt. Replace the distributor cap and put the clamps back on. Attach the electrical connector at the base of the distributor, put on the spark plug wires and coil leads, and hook up the negative battery cable.

How to remove the pick-up coil from the distributor. 1989 GMC 1500 4X4


The distributor does have to be removed and dis-assembled in order to replace the ignition pick-up coil/stator, and if the pick-up coil/stator is faulty then the distributor should be replaced because the distributor will come with a new pick-up coil/stator and the old distributor will have to be removed anyway and in the long run it will actually save money from not having to pay a mechanic to remove and dis-assemble the distributor to replace the pick-up coil/stator, however most of the time it is the ignition module inside of the distributor that is faulty.




When the engine is at TDC (Top Dead Center) is the ignition rotor pointing to the #1 position on the distributor housing as described below?



The engine should be set on TDC (Top Dead Center) with the distributor cap removed, and there is a mark or notch on the distributor housing that the rotor should be pointing to when the engine is on top dead center. (Look under the distributor cap and find where the number one terminal runs under the distributor cap, and where that position on the distributor cap corresponds with the distributor housing, and it should match up to a mark or a notch on the distributor housing)

This static timing is all that matters and the computer will be able to control the timing as long as the ignition rotor is in that position when the engine is at top dead center.



If the engine is at TDC and the ignition rotor does not point to the #1 mark on the distributor housing, then loosen the hold down bolt to the distributor and turn the distributor until the rotor is pointing to the #1 mark on the distributor and then tighten the distributor hold down bolt.

Tengo una gmc la sierra 1500 5.7 vortec ano 1997 le acavo de reparar el motor pero no la puedo poner a tiempo


Clean off the crankshaft pulley at the front of the engine and put some paint on the timing marks. Start the car and turn off any accessories such as climate control, lights and the radio. Start the engine until it warms up.

Connect the timing light to the battery and then to the number one ignition wire. Locate the assembly line diagnostic link also called an ALDL and use a jump wire to connect the diagnostic terminal "B" to the ground terminal marked "A". The ALDL is located under the left side of the instrument panel. Not all models of the GMC Sierra have an ALDL.

  • Point the timing light at the crankshaft pulley to verify the need for adjustment. Adjust the timing by loosening the distributor mounting bolts and turning the distributor until the crankshaft timing mark lines up with the middle line of the timing light


  • Tighten the distributor mounting bolts and recheck the timing. Remove the jumper wire from the ALDL with the engine running. Turn the engine off and remove the tachometer and timing light. Reconnect the number one ignition wire.

    Remove the distributor cap. Mark the location where the rotor is pointing by making a scratch mark on the distributor housing. Remove the distributor adjusting bolt and bracket. Remove the distributor. Replace with the new distributor by placing the rotor on the shaft and turning the shaft until the rotor aligns with the same place as the mark on the old one. Install the bolt and tighten. Start engine. If your engine does not run, remove the bolt and distributor and turn it 180 degrees and replace.

    How to replace distributor


    remove the air cleaner and mark where the plug wires are on the distributor cap. if you get lost the firing order on the v8 is 1-8-4-3-6-5-7-2 remove the distributor cap. unplug the distributor and using a white grease marker mark where the tab on the rotor is pointing. i usually make sure its where i can mark the intake so i can line it up later. go to the parts store and either rent or buy a distributor tool to remove the bolt holding the lock down clip at the base of the distributor. dont let it fall Murphy law says it will fall where you cant get a hold of it lol. after removing the lock down clip the get a hold of the distributor and wiggle it back and forth while pulling up on it it should slide out. when you reinstall it make sure you line it up with tab and your mark. as you put it down in it slides into the tooth of the cam and will rotate as you slide it in so you have to be one tooth before your mark and it should slide into the mark. make sure you use the new gasket with the new one and dont over tighten the lock down bolt. good luck

    How do I change the distributor


    REMOVAL NOTE: Once the distributor is removed, the engine should NOT be turned or moved out of position. Should this occur, please refer to the engine rotated installation procedure. Distributor components — 4A-F engine 88272p61.jpg
    Fig. 1: Exploded view of the distributor — 4A-F engine 88272g41.gif
    Fig. 2: Exploded view of the distributor — 1993 4A-FE and 7A-FE engines 88272g42.gif

    Fig. 4: Exploded view of the distributor — 4A-GF engine 88272g44.gif
    1. Disconnect the negative battery cable.
    2. Disconnect the distributor wire(s) at its harness. Loosen the screws holding the cap onto the housing 88272p05.jpg
      Pull the cap and wires off the distributor housing 88272p06.jpg

    3. On the 4A-F engines, disconnect the vacuum advance hoses. NOTE: On some models the distributor wires are part of the cap and can not be separated.
    4. Remove the distributor cap. Label and disconnect the wires from the cap. On some engines it will be necessary to use a flat bladed tool to lift up the lock claw and disconnect the holder from the cap. Fig. 5: On some engines, use a flat bladed tool to lift up the lock claw to disconnect the holder from the distributor cap 88272g45.gif

    5. Carefully note the position of the distributor rotor relative to the distributor housing (also note position of distributor to the engine assembly); a mark made on the casing/housing will be necessary for reassembly. Use a marker or tape so the mark doesn't rub off during handling of the case/housing. Mark the position of the rotor relative to the distributor housing 88272p07.jpg
      Label and remove all vacuum hoses attached to the advance on the distributor if equipped 88272p14.jpg
      If necessary, remove the rotor 88272p08.jpg

    6. Remove the distributor hold-down bolts. Remove the distributor hold-down bolts before pulling the unit from the engine 88272p13.jpg

    7. Carefully pull the distributor from the engine assembly. Remove the O-ring from the distributor shaft. Pull the distributor straight out from the engine 88272p15.jpg

    How do i remove a distributor in a 1996 gmc sonoma


    Question 4.3 Litre V6 or 2.2 Litre inline 4 cyl.

    Procedure as follows: in either case remove # 1 cyl spark plug and rotate engine until # 1 piston is at top dead center , with a suitable marking pen make a reference mark on crankshaft harmonic balancer and timing mark indicator on engine timing cover. Make a notation on the distributor cap of the number one spark plug wire and also note the remaining wires firing order sequence on cap in order of rotation. Remove cap and note and mark rotor location , make a reference point on distributor body as well as engine block . Remove cap and wires , loosen distributor lock down bolt , disconnect distributor wire harness and label harness for reference to reconnect upon re-installation. Twist as you pull up on distributor , distributor should come out freely with minimal effort but occasionally they can be a little tough and need to be helped out with minimal extra persuasion...

    If you find that upon re-install you get a trouble code P1345 don't threat just start over the process of placing # 1 cyl at TDC and then reference the marks you made during dismantle, There is a + - 3 degrees tolerance that the computer can adapt... But you will have to erase any trouble codes... You should not have to remove the hood, maybe just the air box and or filter housing for easier access.... Unless you are removing entire engine then yes remove hood by all means, mark hood hinges and mounting holes before removing for easier alignment during install of hood... Hope this helps...

    Does a 1991 Dakota 5 2L have a crankshaft position sensor?


    no it has a distributor here is the prodeure for the timing sensor under the cap.
    1. Disconnect negative battery terminal, disconnect distributor lead wire at the wiring harness connector.
    2. Release distributor cap retainers and lift the distributor cap off.
    3. Scribe a mark on the edge of the distributor housing to indicate the position of the rotor. Use the mark as a reference when reinstalling the distributor.
    4. Remove the distributor hold down bolt and clamp, and carefully lift the distributor out of the engine.
    INSTALLATION

    1. Clean the top of the cylinder block to insure a good seal between the distributor base and block. If the engine has not been cranked with distributor removed, proceed with step 2. If the engine has been cranked with the distributor removed proceed to step 3.
    2. Position the distributor into the engine. Make sure the O-ring seal is in place on the distributor housing. Align the rotor with the mark previously scribed on the distributor housing. Engage the tongue of the distributor shaft with the slot in the distributor oil pump drive gear. Proceed to step 4.
    3. If engine has been cranked with distributor removed perform the following:
      1. Rotate the crankshaft until number one piston is at the top of its compression stroke. The mark on the crankshaft vibration damper should be in line with the "0" TDC mark on the timing chain case cover.
      2. Rotate the distributor rotor until it is positioned pointing at the number one distributor cap terminal.
      3. Lower the distributor into the engine, making sure the O-ring seal is in place. Engage tongue of distributor shaft with slot in the distributor oil pump drive gear.
    1. Install the distributor hold down clamp and screw and tighten finger tight. Install distributor cap and wires, making sure all high tension wires are firmly secured in cap towers.
    2. Connect pick-up leads and negative battery cable lead. Set ignition timing, refer to ADJUSTMENT PROCEDURES for timing adjustment
