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. Fig. 1: GM (Cadillac) 250 (4.1L) V8 GM (Cadillac) 273 (4.5L) V8 Engine firing order: 1-8-4-3-6-5-7-2 Distributor rotation: counterclockwise 85872009.gif Fig. 2: GM (Oldsmobile) 307 (5.0L) V8 GM (Oldsmobile) 350 (5.7L) V8 w/EFI Engine firing order: 1-8-4-3-6-5-7-2 Distributor rotation: counterclockwise 85872009.gif Fig. 3: GM (Buick) 252 (4.1L) V6 Engine firing order: 1-6-5-4-3-2 Distributor rotation: clockwise 85872010.gif Fig. 4: GM (Cadillac) 368, 425, 472, 500 V8 Engine firing order: 1-5-6-3-4-2-7-8 Distributor rotation: clockwise 85872011.gif Fig. 5: GM (Cadillac) 429 V8 Engine firing order: 1-8-7-2-6-5-4-3 Distributor rotation: clockwise 85872012.gif prev.gif next.gif

Before carrying out extensive tests to isolate poor running problems, check connections of spark plug wires. This is especially important if plugs, wires, distributor, etc., have been disturbed recently for service. Obviously, this is not applicable to the wireless 4.7L engine.

NOTE To avoid problems, remove and tag the spark plug wires one at a time to ease reinstallation.
For vehicles with an extensive service history, keep in mind that the distributor 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 very important 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.

What is the proper plug wire sequence on the ditributor cap for a 1998 Dodge Dakota 4 cilinder?


For all Dodge 4 cylinder engines, the firing order is 1-3-4-2
All dodge distributors rotate clockwise.
Standing on passenger side number 1 is at bottom left or 7:00 o clock.
going clockwise number 3 plug wire is next then number 4 then last one is number 2 wire.
plug wire number 1 is 7:00 o clock
plug wire number 3 is 11:00 o clock
plug wire 4 is 1:00 o clock
Plug wire number 2 is 5:00 o clock

Change plugs and wire and engine will not acclerate. This is a built 350 short block chevy with pro charger.


350 Chevy engine in what? 1990 Corvette? Who built it, did you?

Sounds as though you have plug wires wrong.
Firing order is 1-8-4-3-6-5-7-2

Distributor Ignition System:
Distributor rotates Clockwise. (Rotor)
Find Number 1 tower on distributor cap, go Clockwise with Firing Order.

Distributorless Ignition System:
VIEWING the engine from the Front of the car.

Spark plug wire connections along the back, starting from Left side going to Right side;
2-3-7-4

Spark plug wire connection towards the Front of the engine;
6-1-5-8

(To guess I would say you have 5 and 7 wires switched)

Left side cylinder order is 1-3-5-7, going from front to back.
Drivers side is Left side.
Right side cylinder order is 2-4-6-8, going from front to back.
