RE: 1994 suzuki sidekick 16v wont start
ok well i was out messing with this and was thinking about code 41. and i came back in and read more and remembered about the tach question. the tach doesnt move. so read some more and found that code 41 means tach signal isnt being generated or seen. i am thinking this could be a noise sensor or wiring. i can cot check the wiring but is there a quick down and dirty on testing the noise supressor?

RE: 1994 suzuki sidekick 16v wont start
suppressors never fail, ever, they fall off or get crashed at engine swaps or wire same, deal ripped apart,
http://www.fixkick.com/IGN_timing/slides...sor97w.jpg

on the 94 it can be in left loom harness, (drivers left not standing left)
Supressor can be near the loom at the left STRUT tower. i think all suzuki its on left top bay, all are or same place but fire wall 96 +
USA drivers left bay side. (on UK cars, different as in England)

you have 41? cranked for 5 full seconds, release key ?
code 41 cuts fuel instantly (hard firmware rules, ending the fire thing. )
code 41 can be, bad coil, bad ignitor. (or bad ECU, )
you said there is no spark at the coil so that is a hard fact and if no spark at the coil the , suppressor gets no input and no possible tack signal ever.
that was 4 parts (cmp , ecu, ignitor and coil) (and the 3 good fuses sure) that is all there is to this.

again, here is how it works,


CMP must work, must work.we test it easy.
ECU must have power and see CMP pulses at 0v 5v 0v 5v, a square wave, cranked can be seen with any analog needle voltmeter made for 50 long years even the $9 one at walfart.

ECU sees that and then fires (a signal small)fires the ignitor, the ignitor is just a huge power transistor, it charges the coil (ECU does the charging) and then the ECU disable the ignitor
and the COIL makes a huge spark... (called Induction coil effect' wiki that now) the ignitor is what replaced POINTS in the old days. but charges the coil the same exact way,
The ECU controls DWELL and timing, here. (you cant)
that is all there is to spark ,

when spark dies .
the ECU sees its dead (via the supressor), sets code 41,(or 42) and then flat refused to inject fuel again, preventing crash and burn as see on TV.

code 42 is CMP dead.
Code 41 means the ignitor is dead. (or coil primary open) or the suppress fell off the harness loom.

RE: 1994 suzuki sidekick 16v wont start
Thank you for confirmation. I didn't think it would fail but with everything I wanted to make sure. I tried to check the coil and couldn't get any readings at all so will pull it out and take it inside as it's in the 20s here. I have swapped everything but the dist so coil sounds like the likely culprit

RE: 1994 suzuki sidekick 16v wont start
the coil is like 5 ohms primary and 20,000 secondary to case./

code 41 is :
coil primary dead. (or said other way the brown tacho wire is dead , no tach signals cracked.)
the ECU can not see the Ignitor pulse.
bad coil
bad ignitor
missing supressor.(fell off lost)
or as always bad wires to same above or connectors pins bad/corroded,. etc)to same devices. (parts)

good luck and hope it warms up..

RE: 1994 suzuki sidekick 16v wont start
Well I replaced the coil. Was getting no reading. Now I'm getting a code 12. Still no start and no spark. Think I have a dead rotor or cap. Waiting for a new set to come in. Oh getting spark from coil

Thx for the help

RE: 1994 suzuki sidekick 16v wont start
did you crank for 5 full seconds? code 41 or 42 take long cranking in the book for the car it tells you how many RPM spins that is, its like 5 full crank shaft spins. but as human i cant count that fast so use 5 seconds as a test rule. (1 potato 2 potato to 5) and release key see if 41 or 42 blink? that is how it must be done. or you miss the boat.
5 spins a second is par , it may take 20 pins or 4 seconds or 25 spins for 5 seconds, see? the book tells this but i do forget the exact number the book.
10 years ago , i forget?

the cap /rotor do not make spark the coil does and you said its dead. the coil is DEAD you said,

and the test (coil tower HV >>>.test spark wire>>> tests spark plug>>>spark gaped to .028" >>> spark plug shell grounded is the test.
this failed failed.
and that means
1 coil bad.
2 ignitor bad.
3 or bad ecu
4 a bad cmp?, bad cmp will be missed dtc seen, if you dont crank long enough. to get the DTC error for CMP dead.


Test the CMP pin with voltmeter (needle kind) set to volts, black to ground, and red to output pin CMP. crank see the needle wag 0 to 5vdc over and over. a good CMP
then we remove it from the list above.


code 42 is bad cmp
gee, unplug the Distributor, lower , case, low voltage connector,
crank for 5 full seconds
release key ,do not turn key OFF yet.
see 42 flash?, see the ECU is not blind to bad CMP. dead. Ive never seen and ECU be dead this way. (well with power on 3 pins to ECU)
now put the cable back to casing plug,
crank again same way, 42s gone?
sure they are?

do not run lacking the DOME fuse or the ECU will not remember DTC errors, key off.
FI and IGCOIL and DOME fuses all must be good.

RE: 1994 suzuki sidekick 16v wont start
you had code 41 before, my guess is you forget to crank for 5 full seconds, missing code 41 again.
keep in mind i cant watch you so , i can only guess you do the tests correctly ok?
good luck to you!!!!
