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 !@!!!!

Ignition reset switch location

Not aware of a reset switch. Could be one of the ignition relays. Could be the crank sensor, camshaft sensor or the ignition module(coils) itself. If your engine has a distributor check that the rotor button rotates when you crank the engine. Any electrical gizmo's in the distributor should be checked also.

Will not start appears that coil does not fire coil replaced

If you have no spark, chances are it's the TFI ignition module. To narrow it down, turn the key on. The check engine light should be on. Now, crank the engine for a couple seconds while watching the check engine light. If it goes out while cranking, the pickup coil is good and the signal is reaching the processor. Most likely, this means it's the ignition module.

I have a 1990 suzuki samurai, engine turns over but no sdpark. changed coil and ignition module. still no spark. what next?

Try checking the contacts between the rotor button and the distributor cap, particularly the center contact to the coil. Hopefully your problem is there because 1990 and later samurais were fuel injected and notorious for faulty ecm's and if I remember correctly it can be close to $1000 for a new one and $200+ for a repair job.

Lumina still won't start until engine cools down for an hour

The coil pak is probably bad.
you need three things to start air fuel and spark. You turn it oven and it wont run,if the fuel is the problem try this.spray a little 2+2 carb cleaner down the throttl body if it runs ,fuel is the problem.
It can also be as simple as the ECM the computer could be going bad.

1987 suzuki samurai dies going down the road. Now has no spark?

Ignition control module within distributor could be bad resulting in no spark or could be the main ignition module
