I am attempting to read trouble codes on my 2001 S3T but instead of seeing the codes flashed in 1 second intervals, the trouble light flashes rapidly about 10 times, then repeats.

Is my ECM malfunctioning or could there be another reason?

Not sure if its the same setup as my old (1991) Dodge, but on that system it flashes 2 digit codes, then a "5-5" indicates end of sequence.

MAYBE if all you're getting is two tens...that could be the Buell end-of-sequence code?

If my ECM is damaged, could I fit one from a post-2002 fuel injected Sportster?

I would not count on that working for a tuber.
I will try to put the manual page on this up.

the codes are preceeded by 6 rapid flashes, ~ 3 per second
a pause ~ 2 sec
first digit on and off are 1 second
pause ~ 2 sec
second digit
pause ~2 sec
rapid flashes like at start
------- next code or repeat
the string of codes will repeat

if the lamp flashes faster than normal you are observing intermission only ( no codes )

codes 11 tps throttle position sensor
13 o2 exhaust o2
14 ets engine temp sensor
15 iat intake air temp sensor
16 bat battery voltage
23 ffi front fuel injector
24 fic front ign coil
25 ric rear ign coil
32 rfi rear fuel injector
33 fp fuel pump
35 tac tachometer
44 bas bank angle sensor
52,53,54,55 ecm fail
56 cps cam position sensor (cam sync)

it sounds like your ecm is ok and you have other issues

un hook the IAT sensor and attempt a start, then check codes (WHILE UNHOOKED) I tested my ecm that way to confirm operation.

Thanks Jim,

The fuel pump is powered up (I can hear i when I turn on the key) but still no spark.

I am not getting any trouble codes so I am now looking for a blow fuse or a bad connection.

I have had some issues with the coil connector

try measuring the resistances
Try hooking the plug side to plugs and the primary side up to a battery, you should get a
spark each disconnect ( switch off )

not sure about the fuel injectors,

With ECM-Spy you can test fire coils and injectors---
