Where should the #1 wire go on the distributor for a 5.7l GM - or doesn't it matter as long as the firing order is right?

Wrong the number one is important. most caps are marked most always GM Small blocks the one is towarws the frount of the car or pointing right at the number 1 cyclinder if nessary and the distrubutor has been removed from theengine or the timing chain is in quesation then the cap needs to be removed and the engine turned buy hand to line up the timing mark on the damper and then see where the rotor on the distrubutor is pointing. As the timing could be off the rotor should be pointing to the number one or number six as the rotor turns 1/2 speed of the crank. With it on the mark watching the dist turn the crank backwards to see if the chain is bad. if the crank turns more the 15 degrees before the rotor moved the chain is too worn and all kinds of running problems are possible. Ifits Ok put the number one where the rotor is pionting and put themon in the firing order. Tighting to bolt on the crank is the direction of retation and watching the rotor turn will tell you whick way the next wire goes. Connect all the wires air cleaner and all and starter up. If it back fires thoubnt the air claener your 180 out and the wires are half a turn off. Switch them from one side of the cap to the other and count it out to see if your still in order and then start it again if it kicks the starter its one to the counterclockwase to far and if it doesn't hit at all or barely runs with little power your to the clockwise one to far

If you stand exactly in front of the engine and look at the distributor #1 wire is to your right and #8 is to your left, exactly in the front of the distributor.
Firing order is : 1-8-4-3-6-5-7-2 rotor is turning clockwise.
This does matter, line it up this way and you will not have a problem.
Always rember on a 350 as you are standing in front of the engine, the right side of the block extends out just a little, that is how you know where #1 cylinder is.
1-3-5-7 on the right 2-4-6-8 on the left.
Please let me know how it goes.

How did you make the determination that all the firing orders are wrong? No matter what the source was, the firing order should be the same no matter who you got the information from. Am I correct on this.....that everybody keeps giving you the same firing order??? As a point of emphasis I would like to know if you recieved conflicting specifications regarding the firing order. You may want verify the calibration of the distributor's position. At TDC the distributor rotor should be pointing to #1 cylinder terminal on the distributor cap, or 90 degrees across from it. Please verify.

    FIRING ORDERS

    See Figures 1 and 2
    To avoid confusion, remove and tag the spark plug wires one at a time, for replacement.
    If a distributor is not keyed for installation with only one orientation, it could have been removed previously and rewired. The resultant wiring would hold the correct firing order, but could change the relative placement of the plug towers in relation to the engine. For this reason it is imperative that you label all wires before disconnecting any of them. Also, before removal, compare the current wiring with the accompanying illustrations. If the current wiring does not match, make notes to reflect how your engine is wired.

    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.

    I installed spark plug wires wrong on a 4.3 gm motor for 2000 gmc sonoma now it does not start need wire schematic to guide me


    Standing at front of truck, looking under the hood.

    The closest cylinder to you on your right is #1. #2 is close left. #3 is middle right, #4 middle left. #5 is back right and #6 is back left.

    Firing order is 1-6-5-4-3-2. This is the sequence for placing the wires on distributor cap in a clockwise direction. #1 spot on cap is the 3rd post after the wiring harness (clockwise). This post should be closest to cylinder #5.
