What's mag what's the mag or coil

wild engine swaps topic, SURE SOME SECRET TOYOTA model.
pin count are not the TOP clue (yes doing it wrong)
no car told or years, (both)

sensors come like this
HALL and mag coil. the can NOT be mixed, !
Hall is 5vdc sensor , has a power pin , signal and ground(3 pins)
a 4 pin is ground shield pin to stop noise (yes 1 or 2 grounds HALL)
a MAG coil is not true electronic like HALL is, it is just coil inside
and MAg COIL HAS 2pins OR 3 PIN 2 FOR COIL AND 1 FOR GROUND IF PRESENT, this signals are super tiny on mAG
for sure crarked and idle RPM. the PCM that needs HALL here is going to fail HARD (CMP hard nut errors)


THAT ENGINE SWAP WILL NEVER MAKE THE PCM HAPPY
EVER.
1zz-XYZ, NO XYZ TOLD (FE)_ 1.8L ? (1998:)?
4ZZ-XYZ NO XYZ TOLD (fe) 1.4l (2002 TO 2007)_
GOT VVT, yes , that too fails. PCM wrong.
tell the 2 cars, and get better answers
years and country .
not told.

Re loosen the magneto place business card between mag. And flywheel retighten mag mounting screws remove business card shine up flywheel with sand paper with the mag off the motor clean rust off flywheel before remounting mag with business card.

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.

Take top off.Look to see if magneto has rust on the coil.if so,get a steel brush,and clean mag,coil.That could be it.Also check to see if you broke the key on the crank.

The "mag" is a magneto and it generates the high voltage pulse to fire the spark plug. The "coil" is about the same thing but it uses a set of points or an electronic ignition to control when the spark is delivered.

just use a continuity check on other coils Jim

unhook your switch's and see if you get spark then

If selled some capacitor or new ignition parts order it always with statement of the serial motornumber and the year of build , because of modifications on marketing technical dicisions can be made for your engine, that can prevent a next disappointment. may be for the problem a new sparkplug the supression capacitor can also be bad a bad sparkplug connection cable .are some small sugestions.
