the method to see if its HALL is the correct schematic.
the one you posted shows the ckp has 2 coax lines the means its COIL VR type,non hall. 3rd in ground.
the other sensor cmp has 3 wire but 1coax. and has power wire to it, no VAR sensors have power to them.
STI may never answer, my guess is they get 1000s of emails a day like that. and are bound by contract not to answer. (with truth, so why answer all them.?)
you only guessing, why the coils are both dead? this to me , means, the ECU is cutting spark. on purpose, not 2 bad drivers. (but i dont know history)
usually only 1 coil shorts, and blows 1 driver
if the owner tried swapping wires (ugh), on coils (ugly event) you then get 2 blown drivers(history matters)
but not normally, a user finds one driver dead and buys a new ECU./coil pack and end story.
those chips are contract chips (driver transistor buffers) and are trade secret..... ( some top ECU rebuilders pay Siemens for the facts, $$$) )
I know one guy that took his to a failure lab ($$$$) and they used nitric acid drip (a pro. machine) that stripped away the plastic case
and the lead frame was exposed, and then the chip is exposed, then with 100x microscope, he saw words on the DIE! (real name of chip is DIE)
they some times are clear., on types. others, are more secret codes. "Buf1234" or the like. but some use internal Makers codes, only the engineers know....
so... there you go.. we had such a lab at Phillips Semi. back in 1991. "customers asked us why it failed, and we answered in depth"

what if both chips are ok. then what? say you found the real names and replaced them both, then what? what direction then?
what if the CPU sees errors on either sensor. and you don't know that>? called barking up wrong tree.
that is why SCANS are first. so the tech knows, what's UP. (ALL ECU' tell you when these inputs are bad)
you could replace all parts 10 times, and it's still dont spark and then find that one CKP coax is damaged in the center of the harness.... oops. you missed the scans telling you CKP is bad.(or intermittent)
the signal is bad.
or on my Jeep the ECU can tell me, the cam and crank are way out of sync. and is cutting spark. (a pure mechanical error inside engine.)
see?
all this begs to ask?
2 coils do not short the same day.
there are 2 coils there, and are not connected to each other. (save power or ground)
one cant short then magically short the other , how could it do that? unless it caught on fire....?
the ecu is just a black box of logic.
with logic boxes (CPU, brains) we first check inputs. not replace outputs until we know the inputs are correct.
after all you can do more damage attempting fixes not bad, then good.
like the FSM states on all cars on the ECU page.
"never condemn any ECU until all inputs are checked and all outputs for shorts."
i think a 10 $ scan tool works on this car.. ever seen an ELM327 based scan tool, for 10 bucks.
connect it up, see if the ECU will scan. keyon, see TPS work, just KEY ON... all do.
if not the ECU is dead or the ECU is not using OBD2 signaling protocols..... its 10 $ check. to find out.... not too expensive
What's in the box, i dont know, only Hyundai knows this. or the FSM book sometimes flat tells you. (on the SENSOR pages) (using OBD2, or?)
I'm told that there are scan tools that work for this box.
you could remove one chip
and then scope the input pin, and crank engine, and see if the spark inputs to the chip are good, if not good, its barking up wrong tree time.
if the inputs to the chip are bad, (spark driver chip) id bet the ECU is cutting spark on purpose...
but that invites wrecking the removed chip that nobody sells...
for that fact alone, id do all i could do to scan it first.
