If you were standing in front(knees to bumper) looking under your hood the #1 spark plug wire is at 5 o'clock and the next wires in order moving clockwise are 8,4,3,6,5,7,2. TIP:the drivers side of the engine cylinder # from front to back is 1,3,5,7(odd) and the passenger side from front to back is 2,4,6,8(even)

Pull a plug wire and spark plug. Put wire on plug and hold with INSULATED pliers against the block, where you can see the spark. Have a helper turn over the motor while you watch for a BLUE spark. if no blue spark but yellow or orange, then you don't have enough spark to fire. It is also possible you have a bad distributor coil, which is mounted inside the distributor. It's kind of involved to change, but possible. Let me know what you find and I'll try to help from there!!

Need firing order on 96 Chevy Silverado and how to place the distributor


Distributor

ABCDEFGHIJKLMNOPQRSTUVWXYZ

Inspect/Replace

To Remove
  • Disconnect the distributor wiring connector and the vacuum advance hose, if the vehicle is so equipped.
  • Remove the distributor cap and note the position of the rotor. Mark the position on the distributor housing.
  • On some vehicles, it may be necessary to remove the spark plug wires from the cap prior to cap removal.
  • Note the position of the vacuum advance, then remove the distributor holddown bolt and clamp.
  • Pull the distributor from the engine. Most distributors will need to be twisted as they are pulled out of their bore.
  • Once the distributor is removed, install a shop towel in the distributor opening to keep foreign material out of the engine block.
  • The entire assembly should be cleaned thoroughly. Make sure all solvent residue is completely removed.
Installing and Timing a Distributor
The following procedure may be followed to install the distributor and time it to the engine, if all reference marks were made during the removal of the distributor:
  • Lubricate the O-ring on the distributor shaft.
  • Position the rotor so that it is aligned with the mark made on the distributor housing prior to removal.
  • Align the distributor housing with the mark made on the engine block during removal.
  • Lower the distributor into the engine block, making sure the distributor drive is fully seated.
  • Distributors equipped with a helical drive gear will rotate at the distributor is being installed, causing the distributor to move away from the reference marks.
  • Pay attention to how much the rotor moves.
  • Remove the distributor and move the rotor backward the same amount. This should allow the shaft to rotate while the distributor is being installed and still be aligned with the reference marks.
  • Make sure the distributor housing is fully seated against the engine block. Sometimes it may be necessary to wiggle or rock the distributor to seat it fully into the drive gear.
  • Distributors with drive lugs must be mated with the drive grooves in the camshaft. Both are offset to eliminate the possibility of installing a distributor 180 degrees out of time.
f22-52.gif The distributor must be aligned with the camshaft drive to seat the distributor in the engine block or cylinder head.
  • Rotate the distributor a small amount so the timer core teeth and pick-up teeth are aligned.
  • Install the distributor holddown clamp and bolt, leaving the bolt slightly loose.
  • Install the spark plug wires in the direction of distributor shaft rotation and in the cylinder firing order.
  • Connect the distributor wiring connectors. The vacuum advance hose is usually left disconnected until the timing is set with the engine running.
If the engine has been cranked while the distributor is removed, or no marks were made during removal, use this procedure to reinstall the distributor:
To be sure that the number one cylinder is on its compression stroke, observe the rocker arms to see that they are both moving. Then, rotate the crankshaft one revolution until the rocker arms for the companion to cylinder number one are both moving at TDC (top dead center). Align the timing mark and install the distributor with its rotor pointing to the number one spark plug cable in the distributor cap.
f22-01.jpg
  • Remove the spark plug from cylinder #1. Install a test plug in the end of the spark plug wire and position the test plug away from you and cylinder #1.
f22-02.jpg
  • Place your thumb over the bore for the spark plug and crank the engine until compression is felt.
f22-03.jpg
  • Lightly crank the engine while observing the timing marks on the crankshaft pulley. Once the timing marks are aligned, stop cranking.
f22-04.jpg
  • Identify the position for the #1 spark plug wire on the distributor cap.
f22-05.jpg
  • Determine which way the distributor shaft will rotate when it is lowered onto the camshaft gear. Then position the rotor so that it will be under the #1 terminal on the distributor cap after the distributor gear is meshed with the camshaft gear.
f22-06.jpg
  • After the distributor is installed in the engine, turn the distributor housing slightly so the pickup coil is aligned with the reluctor.
f22-07.jpg
  • Install the distributor holddown clamp and bolt. Hand tighten the bolt.
f22-08.jpg
  • Connect the pickup leads to the wiring harness.
f22-09.jpg
  • Install the spark plug wires onto the distributor cap according to the engine's firing order. Check to make sure everything that was disconnected before the distributor was removed, is now connected. Connect a timing light and prepare the engine for an ignition timing check and adjustment.

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.

Where is the distibutor cap on a 1993 Jetta Wagon?


Hi, look on the engine block for the place where all the spark plug wires go, and you've find the distributor. Unsnap all clips and take off the distributor cap and suppressor shield, leaving the spark plug wires attached.

Can't locate sparkplugs


Sparkplugs go down into the engine. You have as many as cylinders you have. Four cylinder, four plugs, six cylinder, six plugs. The plugs carry spark through the wires that hook to your distributor cap. Most caps are located on the right of the engine. That cap hooks to your distributor. So, if you have a four cylinder engine, you have four wires. You should see them crossing the engine block. The plugs are down in the engine block. The wires go into the engine block. Unless you have coils, which look like a small square, it has plugs.

How do you check the firing order on a chevy small block engine ?


Firing order for small block chevy is 1-8-4-3-6-5-7-2. The cylinders are numbered 1-3-5-7 on the driver's side of the engine counting front to back. Passenger side is 2-4-6-8, front to back. You will need to get #1 cylinder at top dead center on the compression stroke. To do this, remove the #1 spark plug and remove the coil wire from the distributor cap. You will need a helper for the next step. Place your index finger in the empty spark plug hole, Have your helper bump the starter with the ignition key, When #1 cylinder comes up on the compression stroke, the pressure will push your finger away from the spark plug hole. Don't worry, this doesn't hurt. Turn the key off. Check the timing mark on the harmonic balancer behind the crankshaft pulley. It should be pretty close to lining up with the "0" timing mark on the pointer attached to the engine block. Now pull the distributor cap and see where the rotor cap is pointing. This will be #1 on the distributor cap. The spark plug wire from the #1 plug will occupy that position. The next position on the distributor cap will be for the plug wire coming off the #8 cylinder. The rest of the plug wires will attach to the distributor cap in the above mentioned firing order counting clockwise. If you do not wish to place your finger in the #1 spark plug hole, you can use a piece of paper towel roll up and stuck in the hole just enough to form a seal. When the piston comes up on the compression stroke it will force the paper towel out. Any questions, just let me know.

I took of*** my spark plug wires working on my small block 350 pickup and I don't remember the the firing order to put the new wires back on. Is there a diagram anywhere or is it even that difficult to...


Next time number each lead before you remove it and no. the dissy cap as well

The firing order, which should be cast into the intake manifold, for the chevy small block V8 is 1-8-4-3-6-5-7-2. The firing order is the numerical sequence in which the spark plugs are fired. The insertion position of each spark plug wire around the circumference of the distributor cap can be found according to a clock face. The insertion sequence determines the firing order. The firing order is followed clockwise around the distributor cap starting from the 6:30 position with the 6:30 position being the number one cylinder spark plug wire.
On classic chevy small block engines that use ignition breaker points instead of electronic ignitions, the number one cylinder is the one immediately clockwise of the small metal sash cover on the distributor cap. The firing order starts here. There is no sash cover on the distributor cap for GM HEI electronic ignitions, and the firing order is the same, but starting at the 5:30 position.
The firing order makes sense if you know how the cylinders are numbered. The number one cylinder is the front most on the drivers side and 2 being the front most on the passenger side. From front to back, the cylinders are odd numbered on the drivers side, and even numbered on the passenger side.
See the diagram; Click to open a printable larger image in a new window. The firing order starts with the number one cylinder. We would connect the number one spark plug wire to the distributor cap terminal in the 6:30 position. distributor.pngSince the next cylinder in the firing order is 8 (passenger side rear), we connect the number 8 spark plug wire to the next distributor cap terminal (approximately 7:30 position) in the clockwise direction from number one. You need to be sure you continue the firing order in the clockwise direction around the chevy small block distributor cap from the last installed spark plug wire. Setting the rest of the firing order is just a matter of repetition. Be sure to count the spark plugs from front to back on each side of the motor to identify the correct cylinder number in the firing order.

1997 jeep cherokee 4l will not start on petrol or lpg


Here are a couple of things that could be causing your problem. 1. Bad ignition coil or ignition module 2. Clogged fuel filter 3. Clogged air filter 4. Clogged fuel injectors 5. Bad spark plugs, wires, distributor cap and /or rotor. 6. Broken timing chain/belt. Here are a few things you can try to verify that you have a good spark. 1. Remove the distributor cap and crank the car. If the rotor turned you're ok. If it doesn't turn then that's you're problem and you will probably need to change a timing belt/chain. 2. Check the spark from the ignition coil by pulling the coil wire from the center of the distributor. Use an alligator clip to attach a short wire to the coil wire contact. Bare the other end of this short wire and set it up so it's sitting very close to the engine block. Turn off the lights and try to start the car. You should see a spark jump from this wire to the block. If you don't see a spark it's likely your ignition module or ignition coil is bad. 3. If you have a spark maybe it's not getting to the plugs. You may need to replace the distributor cap and rotor. You can test if the plugs are sparking by pulling one, re-attaching the spark plug wire and seeing if you get a spark when you try to start the engine in the dark. Please note, the metal threads of the spark plug need to be shorted to the engine block to complete the circuit during this test.

#5cylinder miss fired


Hi

Are you sure you are getting a spark to this spark plug ?

Run the engine and hold the HT lead with insulated pliers, near to the block, and you should see a spark jump.
If not, check the distributor cap, for cracks, or tracking marks, if found , renew cap.
Might be worthwhile just checking your compression reading on this cylinder too, if it is down, it will give you this problem.
Good Luck !

Let me know how you get on.

A FixYa rating would be nice...Thank´s ....John.
