Miss-firing Need firing order to coil on a 2.4 L Quad 4 engine?

The firing order for the 2007 Suzuki XL7 equipped with the 3.6L V6 engine is 1-2-3-4-5-6. In V6 engines, the cylinders are typically numbered consecutively from front to rear on each bank. Therefore, the firing order indicates the sequence in which the spark plugs fire in each bank of cylinders.

Firing order is 1, 5, 3, 6, 2, 4. Number 1 cylinder is up front. Why would you need the firing order, this engine does not have plug wires, each plug has its own coil pack, each coil pack is controlled by the computer.

4-cylinder:

Firing Order: 1-3-4-2

3.1 liter:

Firing Order: 1-2-3-4-5-6

a haynes manual from a parts place will show you--or chec the condition of each plug wire-if one looks bad or falls apart--probly need to get all new wires /plugs

Here ya go...found the block for the reply....

3.8L engine Firing order: 1-2-3-4-5-6 Distributorless Ignition System

my money would be on the coil cover, especially if it had been a long time since the last tune up. it is certainly worth trying, as this is part of a routine tune up anyways. good luck!

You didn't post your engine size so please pick the applicable diagram:

1996-98 5.0L, 5.7L and 7.4L Engines Firing Order: 1-8-4-3-6-5-7-2Distributor Rotation: Clockwise




4.3L Engines Firing order: 1-6-5-4-3-2 Distributor rotation: Clockwise



4.8L, 5.3L and 6.0L Engines Firing order: 1-8-7-2-6-5-4-3 Distributorless ignition system (one coil on each cylinder)



5.0L, 5.7L and 7.4L Engines Firing order: 1-8-4-3-6-5-7-2 Distributor rotation: Clockwise

To avoid confusion, remove and tag the spark plug wires one at a time, for replacement.

The 3.5L (VIN H) engine's unique ignition system has the ignition coils directly over each plug. No spark plug wires are used.
If a coil is replaced on any of the 3.1L, 3.4L or 3.8L engines, it may not be numbered, as is the factory coil. 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 guide to reflect how your engine is wired.

The firing order for the 3.1L VIN M, 3.4L VIN E, 3.4L VIN X and 3.5L VIN H engines is 1-2-3-4-5-6. The right bank cylinders are on the cowl side (rear) of the engine compartment and are numbered 1,3,5, left bank cylinders on the front side of the vehicle, are numbered 2,4,6.
The firing order for the 3.8L VIN K and 3.8L VIN 1 engines is 1-6-5-4-3-2. Starting at the front of the engine, cylinders in the left bank are numbered 1,3,5 and cylinders in the right bank are numbered 2,4,6
