One ig/coil failed while 2 coils were ok.

I was started up,checked 2wires at coil,there were 10.8v but no spark out from ig/coil. i swapped over the faulty one with good coil,then fault one was worked ok while the good coil didnt work at faulty place.then i replaced the trigger unit but never changed as a result.

Misfire #8 cylinder


this has individual coils for each cylinder, correct? Why not check for spark out the number 8 coil. if there is no spark swap it with another coil. If there is still no spark out the coil than the coil is bad. If the coil starts to work in the swapped coil location and the swap coil will not work in the number 8 position than there is a problem the either the wiring or the PCM.

What could cause a1991 suzuki samurai to have no fire from a new coil?


no spark from coil directly?
is the cam turning, is the dizzy rotor spinning. ????

check all fuses first. Ig-coil, FI and dome.
then using diagnostic jumper wire or fuse, (as approp)
crank engine look for code 41 o 42.!!!

USA cars , answers only
our cars are all EFI that year.
no engine swaps to Suzuki G16A/B sidekick or tracker engines.!
1: engine cranks
2: no spark
3: The ECu makes spark
the CMP sensor in the DIzzy , (never fails if rotor turns, does rotor turn, if not cam belt igored and now snapped.)
the cam turns. the CMP fires. the ECU takes this CMP signal
and fires the ignitor next to coil and the coil charges, and release and BAM spark.

that is it.
the ECU will tell you when the CMP dies or the Ignitor fails
why not ask it.
1: key on
2: diagnostic jumper in place (flashes 12s for ok)
3: crank engine,for 5sec, not 1 ,not 2.
3: release key not off.
4: see code 41, or 42, BINGO !@!!!!

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.

Fuel relay switch location


old post but im flooding geo posts
so other can search and find answers for this rare old car,
there is no switch
only a relay , actually 2 relays.
one is fuel realy in green socket below ECU and
other is ecu mAIN, next to above in black sockete
if either fails, car will not start
they are same p/n so can be swapped.
if CEL glows in cluster key on, main is ok
are FI and IG coil fues good at left top knee?

no start, just for this car alone.

IF THE PINK WIRE GOES TO 11 TO 12 VDC CRANIING
ITS NOT THE RELAY
IF NOT NEAR 11V, THE ECU IS BAD OR IT HAS NO POWER.
FUSES BAD TOPS LIST
THE FI FUSE MUST BE GOOD
IF THE IG COIL FUSES IS BAD THE ECU IS DEAD, OFF LINE.

I have a p0303 trouble code on my 1999 Passat. Missfire on #3 cylinder. Coil is ok, I'm lost.


coil packs very prone to failing... check compression for good readings (at least 100 - 120psi) if okay try new spark plug as these can fail under load and its the cheapest part to replace to eliminate. if misfire still present swap cylinder 3 coil with cylinder 1 coil and see if fault code moves to cylinder 1. hope this advice helps

2006 dodge caravan, 6 cyl. relaced cole, sparkepugs and wires in oct. 2009. Engine is reading #2 cyl. misfire again. Why


Firts time swap spark plug & ignition coil between two different cylinders and read again if the same #2 cyl. misfires !
If #2 cyl. is OK and another cyl. misfires then spark plug or ignition coil is out of order and must be replaced.
If #2 cyl. misfires again then #2 injector must be checked !
If ignition coils & spark plugs (complete set for 6 cyl.) are replaced then you must check #2 injector !

Fuel pump relay


if it is starting that is normal if not take off your distrubitor cap and check for spark if no spark check the wire going to the coil pack for spark, if very little or no spark replace your dist. cap rotor and coil pack.

1993 Chevy Cavalier 2.2 not firing on 2 cylinders


The reason I'm asking this is because a dual coil fires BOTH plugs at the same time. If one plug doesn't fire right, the other won't either, even to a point that neither does. Kepp the coils where they are and swap the plugs and wires and see if you have a change. Let me know
