the injectors not firing.
only question is why.
did you crank for 5 full seconds with the diag jumper in place, release key then see code 42,41, or 21,22 ? (keep in mind 21 is reverse of 12, can be easy to be fooled with that japan silliness idea)
I think the ECU thinks there is no spark , but spark is ok, and runs on test fuel as you said,see #1
1: the tiny Ignition suppressor. fell off? its just this tiny plug in the harness. code 41, after 5 full seconds of cranking,
2: RPM gauge there, does needle move to (0.3)a tiny bit engine cranked? (evens sparkplugs out for faster RPM ) code 41 again, if tacho is 100% dead, can be hard to see need move 0.3.yes.
3: TPS stuck at WOT, The TP pin goes to 5v, if the TPS ground is broken,(or TPS cracked in half) and it will never inject , like this, this is called magic, unflood mode in the ECU (my name)
4: injector harness below intake not seated.
5: 12vdc not making it to the injectors key on. (fuse) see #4 we know FI fuse is ok because ECU has power,. code 12, takes power.
see suppressor here. and TPS.

the 96 and up suppressor is here. (my be lower on 95 , near the left drivers (LHD USA) strut front. harness.

measure voltage on TPS pin 3
cranking for 5 seconds, is the key to seeing all codes. on a dead engine. (dead injections)
for sure. crank release key dont turn off for say 2 minutes
see of codes other than 12 roll out, also many codes can roll out , and no 12s in the set.
codes means DTC errors.
