Question about 2003 Chrysler Sebring

Dead cylinders 2003 sebring

2003 Chrys Sebring 2.4 sohc [mitsubishi eng]
#1 & #3 cyl's dead
disconnect #1 & #3 inj wiring, engine does not change. Like cyl balance test has 180 lbs compression on all cyl's. Proper fuel pressure, spark on all 4 cyl's.
Have changed plugs, wires, & coils. Swapped dead cyl #1 injector with good running cyl #2 cyl #1 still dead
Replaced cam sensor performed noid test all injectors noiding. Replaced plugs & wires multiple times has good spark on all cyl's
Spark seems to be hotter as you let off on key like an old dodge would do when ballast resistor was bad.
Please help me going out of my mind. Next thing to do change crank shaft position sensor. Does this vehicle have an ignition module and could this be the problem? Is this or computor.

It sounds like you may have the wires on the wrong coil. It should be #1 on the #4 coil, and the #3 wire on the #2 coil. you probably have them backwards so 1 and 3 are firing on the exhaust stroke.
the firing order is 1-3-4-2.
they should be hooked like this.

Firing order for a 1999 nisson quest van


Believe it or not the firing order is 1-2-3-4-5-6 The cylinder locations are 2-4-6 in front by radiator, and 1-3-5 against the firewall. If you have a misfire on a certain cyl. and you've replaced the plugs,wires and cap and rotor, you probably have a fuel injector that's dead or plugged,it's common on Quests. Figure out which cyl. is misfiring and unplug the fuel inj. conn. with the engine running and listen for a change in RPMs. If there is no change then replace the injector.

first question is it a four cyl? or six did u change the coil pack plug wire if a four cyl? did u use ngk plugs to replace the plugs? or it may be a fuel inj you would have to swap fuel injs with a different cyl to see if it follows the inj or stays with the cyl, if it stays may need to diag that cyl further compression check etc

I know how to find tdc on car but i am not sure on how to put distributor back. I turned engine over and forgot to mark rotor, what should it be pointing at on the cap. Thank you, Joe


As the distributer is being slid in, it will rotate some. You want to slide it in and as it rotates you want to align the rotor to where the number 1 spark plug wire will go. I don't know if you have the 4 or 6 cylinder:

I need the firing order on a 1999 chrysler sebring lxi. i know its 123456 but i need a diagram on the engine


153624 on a six cylinder. This should be in cast on the intake manifold. To locate what tower to use on the cap, do this. pull the #1 plug. Bring it to tdc on the compression stroke. Now chk out where the rotor is pointing and that's the tower for #1. Good Luck -Ned-
