I have just completed a tune up on my 1998 Ford Expedition 4.6 L V8 and the truck is backfiring and I can nor find the problem. I have the feeling that I crossed a wire and I cant figure out which on. ...


it definitely sounds like that you have a wire ,or wires crossed on the distributor cap, the firing order should be on the intake manifold, the best way to see what the direction of fire is , is to remove the distributor cap, and have someone crank over the engine, to see what direction the rotor is turning, then after cap is put back on, look for the #1 firing position on the cap, this will be # 1 plug wire, then you will have to continue onward following in the direction that the rotor turned, on the cap, following the firing order, 1 plug wire at a time.

Took the distributor out and cleaned it then put it back in and now the truck wont crank but tries to do so. need some tips please


Did you take out the ENTIRE Distributor or just the cap?

If you took out the entire Distributor, and put it back in, there is a possibility that you put it in backwards. The bottom of the Distributor has a 'notch' in it. If you turn it 180 degrees the wrong way, and put it back in, your truck will not start, because it is in effect 180 degrees out of alignment with the timing.

If you only took out the cap, refer to your owners manual (Hanes is best) for the plug wire placement in reference to the firing order, and make sure all the plug wires are in the correct locations. Also, make sure your plug wires are seated all the way down onto the plugs, and the cap is secured tightly onto the base of the Distributor.

Make sure your Coil Wires are also seated properly to the coil and the Distributor.

Clean the battery connections. Remove the battery connections, clean them and reinstall.

FIRING ORDERS NOTE: 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 in your book to reflect how your engine is wired. Fig. 1: 2.2L Engine Engine Firing Order: 1-3-4-2 Distributor Rotation: Clockwise 89642gf1.gif

To avoid confusion, replace spark plug wires one at a time. --- Distributor REMOVAL & INSTALLATION Although the distributor can be removed from the engine no matter which cylinder is about to fire, it is a good idea to have number one cylinder at TDC before distributor removal. 1.5L, 1.8L, 2.4L SOHC Engines
  1. Disconnect the negative battery cable.
  2. Disconnect and tag the spark plug wires from the distributor cap.
  3. Disconnect the distributor harness connector.

  6. Align the distributor housing and gear mating marks.

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 have a miss fire


Recheck the firing order; 1-6-5-4-3-2

On the distributor passenger side radiator to fire wall. 2-4-6-coil
On the distributor drivers side radiator to fire wall. 3-1-5

Cylinder passenger side radiator to fire wall. 2-4-6
Cylinder drivers side radiator to fire wall. 1-3-5

Good luck and also check the distributor cap again for proper seating.

FIRING ORDERS

To avoid confusion, ALWAYS replace spark plug wires one at a time.

The most important thing to remember about the removal and installation of a distributor, cap or spark plug cable is that all wires MUST be labelled before they are disconnected. Keep in mind that these figures depict a firing order where the distributor cap terminals are relative to EACH OTHER only and they do not necessarily depict the tower positions in relation to the rest of the engine. This is true because any distributor which has been removed and reinstalled may have been installed with the No. 1 spark plug tower at any position (360 degrees) in relation to the rest of the motor, as long as the rotor aligned to the No. 1 tower when the No. 1 cylinder was at TDC of the compression stroke (valves closed, ready for the plug to fire). As long as the remaining wires were connected in the correct firing order sequence (depending on direction of distributor rotation) the engine will run. DO NOT EVER remove more than one wire from the distributor cap at a time unless you tag ALL wires and towers to assure proper installation.

I hooked up the spark plug wires wrong on the distrator cap it is a 1988 4.3L 6cyl how can i find a diagram to fix this problem or tell me hoe to fix it


find the firing order which is usually on the intake manifold,put the crankshaft on 0 degrees top dead center,pull off the distributor cap and mark where the rotor button is pointing,start #1 cylinder at that spot(which that spot should be pointing towards the rear of the distributor),and # 1 cylinder is front of engine on the drivers side then it goes next 1 back #3 then # 5,and the passengers side front is #2, then #4,then #6 towards the back,and the firing order goes clockwise on the distributor.if it spits and sputters or back fires,then the timing firing order is off 180 degrees,so move every wire to the exact opposite on the cap,so your #1 plug wire will be opposite from where you put it first.then double check the firing order and all plug wires then try it.the firing order is:165432,i still dont know how to send pictures.
