 For these coils from rock auto - 

the alternate part numbers say BOTH 56B10 and 56BL0. They are stating it works for both 92 and 94. how do i find the correct one?
the BL is newer version only,  why ? knowbody knows.

you said 10/13 you bought  coil from napa./

and same post I stated this.

he coil is the same 91 to 95 , 8v. a coil can arc over inside this old,  unseen, and is old . the factor  p/n is:  below
in 1992/93 to 94 the coil changed Pn, just looked it up in EPC

and 8v coil same as 16v coil but same rules on 92 , 94 change.
33410 is prefix code on all
suffix is 56B10 (92/93)  and 56BL0  (L) is 94/95
1991 same as 92, coil. 8v only car , no 16v sold then USA.
and never older. years, for this coiil
you need the 56B10 coil. for sure.

the coil BL may work  on all 91 to 95,  is my guess, but not sure, me, above is EPC book facts. electronics parts catalog suzuki.

testing any coil is not easy.
the 2 resistance tests,  primary and secondary are tested with a DMM at 0.5vdc, small voltge
the coil runs over 10,000 volts and at 10kv, the coil can arc over inside there is no DMM made that can find bad internal insulation at 0.5vdc. un less a dead short and no spark from coil never again.
The cod 41 might fail (theory) if the cam belt is loose, ever replace it?
the cam belt loose makes the CMP in the Distibutor JOG wildly.
the ECU man not see that jog, it only counts CMP pulses and not jogs (ILLEGAL)
so that means spark acts funny,  with a jog the coil dwell can be way off (too small) and spark HV is weak. as a result.

if you uses timing light and inject the timing freeze jumper the spark flashes on the crank pully at 5DTBD must be steady.  if not the cam belt is loose
or the freeze jumper is ignore for these reasons,  idle switch bad.


the problem with the freeze jumper is many ways it can fail.
not hot engine, 180F+
idle fails to hold 800rpm and regulate or due to idle switch in TBS bad or set wrong.
ECU is high idle up mode, 3 ways, to get that, AC on, PS overload, transmisson A/T in gear. DRIVE REV. etc.
RPM out  of control
and limphome mode.

this test is not easy to do and to find bad CAM belt , unseen, using this tactic above.

how old is that belt, cam, ever seen it?,  or see it flop around like mad?

Suzuki did not tell what the BL changes are. at all
but wait suzuki real web site tells BL same 92-95 so that means it is and upgrade.
for sure.

not wrong, but correct.


so when buy parts look there first, to see if there is and upgraded part #. (if not missing there as many parts are)
omg some parts there are BACK from the dead for 5 years running, amazing fact there , even front 4wd hubs.(bearing) are back. wow !

the ignitor is gone but the part is listed with Part numbers. 3337054A50


cheers and good luck with code 41,  coil + igniter,+ cam belt loose theory/ and wires and connectors bad, on parts related.
