2002 stratus cyls #2 and #3 are not firing

fzr firing issue The FZR Forum


Hope this helps, Nik.

Coil lead #1 on far left goes to #1 cyl.
Coil lead #2 Goes to #3 cyl.
Coil lead #3 Goes to #4 cyl
Coil lead #4 goes to #2 cyl thats looking from front of car. from left to right

The firing order is 1-2-3-4-5-6
Cyl #1 is front left when looking at engine front to back
left coil pack connects to cyls. 5-2
center coil pack connects to cyls. 3-6
right coil pack connects to cyls. 4-1
It doesn't matter which connector on the coil you use just that the cylinder is connected to the proper coil pack (the coil fires both plugs at the same time, twice per each full 4 stroke cycle)
1998 Chevrolet Lumina
3.1 liter V-6 VIN "M"

Well the 4 cyl engine uses a coil for each cylinder, and the 6 cyl uses one coil for all 6. Both systems use signals from the engine computer to fire the coils. So the RPM circuit would involve the engine computer. No distributor is used.

The number one cylinder is always in the front of the engine.
The 4 cyl engine uses one coil for all 4 cylinders.
The 6 cyl engine uses one coil on each plug.

My sincere apologies for the delayed response.
I am personally going back to answer your unanswered questions.
I have only been a free contributor to this site for the past 4-months.

I do not know if you still need this information, but I am going ahead and answering it anyway.

I do not know if you have the 2.5L (4-Cyl), 2.8L (6-Cyl), or the 3.8L (6-Cyl); however I have included all three below.

For the 2.5L (4-Cyl)
Firing Order:
1-3-4-2
Cylinders:
(back of engine)
1-----2-----3-----4
(front of engine)
Ignition Connections:
(back)
o <-----1
o <-----4
___
o <----2
o <----3
(front)

For the 2.8L (6-Cyl):
Firing Order:
1-2-3-4-5-6
Cylinders:
(back of engine)
1--------3--------5
2--------4--------6
(front of engine)
Ignition Connections:
.........(back)
|.1..4.|.|.6..3.|.|.2..5.|
.........(front)

For the 3.8L (6-Cyl):
Firing Order:
1-6-5-4-3-2
Cylinders:
(back of engine)
2------4-------6
1------3-------5
(front of engine)
Ignition Connections:
Type I:
(back)
6..2..4
3..5..1
(front)
Type II:
(back)
|.3..6.|.|.2..5.|.|.4..1.|
(front)

Let me know if this helped, or if you have any additional information or questions. Feel Free to contact me at FixYa.com!

Again my apologies...

the Wires Go Accordingly to prospective Terminals, So Sorry Unable to Send Pics through FixYa, A Formating Problem Exists
and they show on my end but not on your end this is TRUE and CORRECT To The BOOK other than the Lines from Coil to Spark Plug ENDS at CYLINDERS. Please dont Forget to RATE Me
Thank You And Happy Motoring!!

cannot be specific, had a 98 (now a 99). remember they fire twice- compression and exhaust. if you don't get and answer soon, look up firing order and everyother one should fire together, limiting combinations to two. It doesn't care what stroke it is on

hi from uk hope this will explain TDC valve positions ? when the crankshaft is at tdc this means that numbers 1 and 4 pistons are both at tdc but only one of the cylinders are on firing mode so if let us say in relation to 4cyl engine the fire order is 1 3 4 2 the c/shaft is at tdc ? but for which cyl ? 1 or 4 ? to check look if the camshaft mark is at its mark or check rotor arm ?if at 1 or 4 ? if it isat no1 cyl then both of the valves for that cyl are fully closed whilst no4 cyl valves are at the point of exhaust valve just closed and inlet just about to open this is correct for tdc number 1 cyl firing stroke ?ok so far ? now then if c/shaftmark is atTDC it may be number 4 cyl ready to fire? that is because the camshaft rotates at half speed to the crankshaft soyou need to rotate crank 360 deg to bring cyls 1 + 4 to tdc again then it will be cyl 1 at tdc on firing stroke along with rotor arm at No 1 plug lead and both valves for No 1 cyl will be closed (the cam lobes will be facing up whereas No 4 cyl valves will be pointing down ) hope this is clear for you to understand? if you look at any 4 cyl engine the sequense is the same for No 1 TDC but firing orders may change ie fords 1 2 4 3 is fire order they use as apposed to 1 3 4 2 ? OK? CURIOUSE why you asked? but best wishes and merry xmas from uk

i have the same problem could someone please help ? its getting cold outside and i live 30 miles from my job.
