Suzuki Swift T3 conversion - engine no start

[fixkick]

A quick question. When I read your page on noise suppressors, can you confirm that a working noise suppressor is essential to engine running for 8v sidekicks (with a 3 wire noise suppressor) and/or the 16v MPFI sidekick (which has a 4 wire Noise suppressor)?
sure is , unplug it and engine dies in 1sec. for sure. and by law.

Also is a working noise suppressor only essential to ignition working because the Sidekick ECU design requires a tach input signal to the ECU?
The reason I am asking is that it seems that the igniter is responsible for supplying a ground path for the ignition coil - terminal on sidekicks.

Each and every Suzuki made (reall all EFI cars all years)
all cut fuel with the loss of spark (precursors)
all do
ours all cut fuel on tachometer loss.
The signals on the neg coil are huge. so suzuki uses this supressor, its really a divider shaper. for the tach, other wise the back EMF from the coil primary likes to blow up sensative electronics, in a tach or ECU/PCM. cruise.
so it lower this voltage to a safe and sane level,

it seems your car is more complex ignition and no schematic for it like we have for ours.

basically the ECU fires the ignitor gate. (transistor)
if the the ECU monitors in some way (deep in the secret turbo ignitor) it monitors the Drain pin this is coil minus
if the coil is open primary (ohm it yet>?)
the ignitor is shorted, drain to say source, or is blown up , open the
monitor sees no signal, and cuts fuel, and sets 41.



look here again.
the ignitor iS just a transistor, in your case it has the suppressor built in, btw, it does more than that.

ive drawn in the actual ignitor circuits, see that transistor there, that is REAL, replaces POINTs from olden days.

Your books seem to not have full info on the ignitor,
(a drawing of the guts would be useful)

the ECU drives the gate for dwell time, this charges the coil, then while its charging the CKP/CMP fire and the ECU then release the ignitor and INDUCTION happens. spark
this i how it works if the ECU sees a dead pin a1 on above drawing , fuel cuts and 41s set.

how yours does that , ive no clue, no ignitor , but the book told you what pin is dead, IGT
there are 2 pins,
one fires the ignitor (gate)
and the other is read back.
