Jeep 3.7 cylenders 2 & 4 not firing


3.7 V6, mileage?

most likely the HV wires bad.

then bad coil pack.

did you check spark directly at the coil pack?

i use 2 known good HV wires to do that and 2 good test spark plugs.

both plugs grounded to engine (shell)

that is how you test any wasted spark coil pack. 3 coil pack.

if that fails the FSM shows, unplugging it and check the coil resistances. if wrong the pack is bad,

keep in mind the res. can read ok and coil be bad ,due to internal insulation break down (internal shorts)

if thats ok. the resistance , make sure the wires are not (primary)

to the coil (the low voltage connnector)

if that is ok, its mostly likely a bad coil, (pray not bad PCM)

if tool-less? start with cheap parts , work to expensive. (guessing)





now wasted spark 101.

if one line opens , both spark plugs die. no spark

the wasted spark is wired in SERIES. ( like Christmas lights)

the magic cuts cost of 6 coil\'s.

so if the HV wires are say, cheap , carbon wire and open

you lose, both spark plugs. use MAG wire and end this issues.

get some nice NGK mag wire or Bosch Mag wires.

you can see i hate carbon wire. for good causes.

(carbon string wire)

mag wires is real wire that is coil spun and is inductive. it

has the correct impedance but is not a resistor its and inductor.

and lasts the longest , and worth every penny.

Plugs 1 & 4 no fire?


V-6 I ASSUME? MORE THAN LIKELY, 3 COIL PACKS CONTROL 2 CYLINDERS EACH. MAKE SURE YOU ARE GETTING A SPARK FROM THE ONE THAT CONTROLS 1 &4...OR ALL WIRING IS INTAVT
** IF THIS IS A 4 CYL. SAME THING...LESS COIL PACKS IE: ONE COIL PACK FOR 174 AND ONE FOR 2 & 3

I have a 1999 mondeo 2.0 16v zetec which has a random misfire when driving normally occuring at constant speed like 40mph, have changed plugs, leads and air filter.. still no joy


I HAD A 2004 FORD FUCUS THAT WAS DOING THE SAME THING I HAD A HARD TIME WITH IT
IT WAS THE COIL PACK IT STARTED GIVEING RANDOM MISFIRE CODES AND FINLEY NUMBER 4 CYLENDER QUIT FIRING AND THAT WAS THE ONLY REASON I WAS ABLE TO FIGURE OUT THE COIL PACK WAS GOING BAD THE HOLE TIME
I HOPE THIS IS SOME KIND OF HELP YOU CAN TAKE THE COIL PACK TO THE PARTS STORE AND HAVE IT CHECKED YOU CAN DO IT YOUR SELF WITH A VOLTS METER BUT I'M NOT SURE WHAT NUMBER IT IS SUPOSED TO PUT OUT GOOD LUCK!

Had a problem 350 miles from home and had to drive the car home running rough. Stopped at an Auto Zone and the reader said number 3 cyl misfire... changed the plugs and got it home however it is only...


Hello Vance.
Not too likely a fuel injector problem.
The ignition system on thes engines were much more prone to bad coils and spark plug boots.
Remove the cover again and inspect carefully the rubber boot that go over the spark plugs for burn marks.
If they appear Ok do the same on the coil/module assembly.
I believe the boots are available separately from the coil/module.
When you buy the parts required also get some di-electric grease and apply a thin layer to the inner part of the boot at the spark plug end.
Hope your repair goes well.

How do i plug in the spark plug coils? what order?


If it's the four cyl., the first coil pack bolts over the #2 spark plug. The #2 coil pack wire plugs into #3 spark plug. The number two coil pack bolts directly over the number four spark plug, and the #2 coil pack wire plugs into the #4 plug. The firing order is 1-4-2-3.

Problem with fireing order on suzuki 1.3 w/coils pack


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
