New spark plugs new wires old distributor timing changed wen nee plugs were put on, clockwise or counterclockwise, don't know, besides the battery what firing order V8 305?


I don't know your year--make--model? You should be able to remove dist cap, crank the engine, watch which way the rotor turns, then you know the direction of rotation. Most chevy rwd v8, firing order, 18436572. The driver side bank is odd numbered, 1357.
The passenger side bank is even numbered, 2468 from front to back. Put your number one piston on tdc of compression stroke. Then whichever spark plug tower the rotor is leading into, should be number one, then you follow the firing order around the cap.

I have a Chevy 2500 pick up truck. My son thought he'd replace the spark plugs. He removed the distributor cap, didn't understand it and now the truck won't start. He did not replace any spark plugs.


firing order for 5.7 v8 is 1-8-4-3-6-5-7-2 mostly all of the chevy v8s are the same firing order. the rotor button in distributer turns clockwise, the cylinder numbers are 1-3-5-7 on drivers side, 2-4-6-8 is on passengers side. To get started get your distrutor cap[new one] look on the top you will see a #1that's where you begin you must know if if rotates clockwise or counter clockwise start in that direction then follow the firing order and cylinder line up. good-day!! if cap is not marked, just pull out #1 plug, put a straw or similar in plug hole on top of piston. turn engine over by crank in front of vehicle with a wrench, when the piston comes to the very top just before it starts going down. this is tdc. and rotor button should be pointing to #1 wire on dist, cap. follow from there. good-day !!

i mixed the distributor cables up,so i need the order to correctly connect


If the wires are still in the distributer, AND, if you have a stock intake manifold, the firing order is on the manifold. If it's a V-8, the number 1, 3, 5, & 7 plugs are on the drivers side of the engine. The number 2, 4, 6, & 8 plugs are on the passenger side. The number 1 plug wire can be located by looking at the distributer from the front of the engine and visually looking between the distributer and the number 1 plug. Visualize the distributer as a clock. The number one position should be located between 4 and 5 o'clock and should have the longest wire of those on that side of the distributer.

If the wires have been pulled from the distributer, then, then, remove the rotor cap, turn the engine over slowly until the rotor is pointing to the number 1 plug. Using the firing order on the intake manifold, starting with number 1, replace the wires going clockwise around the distributer.

I need to know what the order on the distributor cap in for the plugs are I know the firing order I just go the last two wires mixed up on the drivers side so I know it's 1-3-5 but where are the locations on 1-3-5 on the cap.


You need to determin which direction the rotor button turns when the engine is running. Take the cap off and get someone to bump the starter . Watch the rotor. If it turns counter clockwise the fireing order will follow its order counter clockwise on the distributer .In other words # 1 wire on the distributer goes to # 1 spark plug. Then the next wire counting counterclockwise goes to # 3 plug . Follow the firing around the distributer for all the wires. counter clockwise is the oppisit to the rotation of the hands on a clock .
