2001 ford windstar-new coil pack,new spark plugs and new wires....same problem. cyl. 3 & 4 not firing. Plugs good wires good. Getting signal from comp. to coil, 2nd coil pack. No corrorion on wire connections on comp. or coil. Were do I go next?

FIRST OFF LEARN THE RULES OF WASTED SPARK COIL PACKS
1-IF ONE WIRE OR PLUG GOES OPEN, YOU LOSE 2 PLUGS DEAD THAT IS BECAUSE 2 FIRE AT ONCE, AND IS WIRED IN SERIES
2-DO NOT MIX IF THE WIRES OR FIRING ORDER IS LOST (HORROR 1)

3- LEARN TO REPLACE HV WIRES 1 BY 1, NOT MIXING THEM UP EVER.
YOUR PACK IS 6 IN ONE, AND HAS 3 COILS INSIDE FIRING IN WASTED SPARK ORDER. IS THIS CLEAR? AND ANSWERS IT ALL.

4- WELL THE HV WIRES ARE FIRST TO CHANGED OUT WITH NEW SPARK PLUGS AS 17 OLD PLUGS AND HV WIRE SETS ARE NO GOOD UNLESS NGK MAG WIRE, NOW THAT IS A WINNER THOSE, NOT CARBON CORE OR SILCONE CORE JUNK WIRES EVER,SEE NOW MOTORCRAFT SAVED OUR BACON,

SEE PHOTO BELOW FOR FIRING ORDER.
ON TOP OF COIL CLEAR AS DAY 6" SEE 3 AND 4 THERE, THEY FIRE AT THE SAME TIME.
AS DOES 2/6 AND 1/5

5: CYLINDER #1 ON ALL V ENGINE IS THE ONE MOST FRONT
IT IS OFF SET TO THE FRONT MOST. BINGO #2
THEN WE GET ASKED THE FIRING ORDER.
6: THIS IS NOT GUESSING THIS IS SERVICE MANUAL FACTS .
BANK 1> 1,2,3
BANK 2> 4,5,6
VIN U) Firing order 1-4-2-5-3-6
SEE HOW ALL THIS MATTERS?

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.

I would say its the coil. A crank or cam sensor could cause one cylinder to miss, or go completely dead, but I doubt it would affect two cylinders. And you would get a code for either sensor.

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 would suggest you run a compression check on this engine and also have the coolant recovery tank tested for the presence of combustion gases with a gas analyzer, any gases would indicate a leaking head gasket. Any engine cylinder that is lower than 5% of the highest reading cylinder in pounds per square inch has a problem like a scored cylinder or leaking intake or exhaust valve seat.

Check engine light on ? Code's ? What engine ? 2.3 l 4cylinder or 3.ol v-6 This vehicle has coil on plug ignition system , not coil packs ! a coil per cylinder . If new coils an still has no spark , has no B+ voltage to the coil or the PCM isn't controlling them . Without testing i'd only be guessing as to the problem .If the repair shop you had it to can only say it had to be the coils , I'd find another shop to take it to !
Autolite Coil on Plug Ignition troubleshooting

check your coil I have seen alot of the fords with the ohv 3.0 engines that the coils will have cracks in the plastic and jump fire ground out etc. if thats not it take some carb cleaner and spary around your intake and listen for changes in the running for a vacum leak. hope this helps.

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.

You are mis fireing on cyl 1 and 3 if you replaced plugs and wires and coil this is going to be a fuel injector issue or valve issue. See if you can swap the injectors with known good cyl. and see if it changes. Or have a shop do a fuel injector service on it to see if it helps. It may be to late for the fuel injector service.
