1992 sidekick,  4door,  16valves, G16B engine right?

keyon CEL  must glow
then when this jumper is planted

the diagnostic connector under hood, jumper in place.   (4 or 6 pin DLC<  which one is yours) guess 6
jump 2 to 4 (unbent paper clip jumper)

key on, CEL lap flashes code 12 for happy. or see other DTC errors now. (share them all) please.
the CEL MUST not be dead. or thE ECU is dead or its fuses blown.

yes crank for 5seconds  release key not turning it off (the rule IIRC is crank spins 10 times or more)
see code 41  DTC o r 42 is spark failure.
If the ECu sees the tachometer  wire dead , it will tell you it is dead.

42 is dizzy cmp sensors dead, or cam belt snapped or stripped out.
41 means tachometer single dead. (41 and 42 both can happen) they roll out 1 at a time 41 then 42 , repeats.
the top cause of dead G16 engine, & compression weak is the stripped out cam drive belt.
when the belt does that the cam timing is grossly retarded, (late) or the belt snaps. and dizzy rotor  does not spin.now.

keep in mind this car loves to strip out crank end  bottom cog key there. not torqued to 94ft/lbs.

even a bad ground to the dizzy kills spark dead.

the wiring is like this, 16v up to 1995
the ECU creates spark, but needs  working CMP
see pin A4

the dizzy  blue/blk wire most be 12vdc keyon.
bk/green is ground 0v.
the spark coil blk/white wire 12vdc key on
the ECU pins A12 and A13 must be 12v. same power as wire to dizzy above, blue/blk
all ground seen on ECU must not be  bad, all are 0vdc.

check spark only at the spark coil HV lug , unless it passes this test.
good luck to you.
