Hi,
Isuzu seem to have complicated things by changing engines, firing orders and even direction of rotation! As you can see, they've numbered the cylinders the other way than the 3.2L.

The Firing sequence for the 3.1 (traditional distributor) 6 cylinder is as follows -

If you take the distributor cap off, there should be a "No.1" formed on the inside. Stick a lead on this before you put the cap back on and go from there.
As leads are different lengths, you may have to swap a few to find the best fit.

I think 2 of them will look out of place - but that's the way it's designed. Just make use of clips for holding them neatly.

Thanks for using Fixya.

I need to know where the plug wires go.from spark plug to distibuter cap on a 1986 4.1 coupe deville(cad.)


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.

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 replaced my spark plug wires on my 1996 chevy truck. may have crossed one,need a diagram from the spark plugs to the distributer cap.


Since you didn't state whether it is a V6 or V8, I'll give you both.

V6 -4.3Liter
Firing Order is 1-6-5-4-3-2
Distributor rotor turns Clockwise
Number 1 spark plug tower on distributor cap, faces the front of the engine.

->Drivers side, spark plug order in engine, starting from the Front going back:
1-3-5
->Passenger side, spark plug order in engine,
starting from the Front going back:
2-4-6

If it's Electronic, the distributor cap has a Left side, (Drivers side), and a Right side, (Passenger side)
Starting from the Front, going back on the Left side,
3-1-5
Starting from the Front going back on the Right side,
2-4-6

V8-5.0, 5.7, and 7.4Liter
Firing Order is 1-8-4-3-6-5-7-2
Distributor rotor turns Clockwise
Number 1 spark plug tower on distributor cap,
faces Front, towards the Drivers side.

Electronic distributor cap has two sides. Drivers, (Left), side and Passenger, (Right), side.
Starting from Front going back on Drivers side,
1-7-3-5
Starting from Front going back on Passenger side,
8-2-4-6

Spark plug order in engine, starting from Front going back, Drivers side:
1-3-5-7
Spark plug order in engine, starting from Front going back, Passenger side:
2-4-6-8

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...
