4 out of 6 coils not firing - 2001 Chrysler 300M

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.

if you have 12v and a switching signal but the individual coil wont fire,
verify its the coil by switching it with another cylinder. if the problem follows the coil to the other cylinder you must buy one

Crank sensor if it has one,timing belt skipped is a possibility,and always the dread security key problem.don-ohio

This is either a wiring loom issue or a ECU issue.

on the straight six you will remove the bolt holding each coil to the valve cover. Remove one coil and use either a spark tester or a test light. If there is spark the coil is good. If there is no spark swap that coil with another. If the swapped coil fires than you know the circuit is good. If the coil that didn't fire still doesn't fire than you know the coil is bad.

Did that help?

If you have any questions let me know.

check the fire to the coil pack if it's present then check the pulse to the crank sensor

check wires an plugs also

Your firing order is 1-3-4-2. There are 2 ignition coils under the cover sitting on top of the engine. One coil fires cylinders 1 and 4. The other fires cylinders 2 and 3.
