the ECU will show code 41 or 42 , DTC errors, if CMP or igniter fails
but engine cranked for 5 full seconds (20 crank turns)
DLC, jumper for diagnosics
code 12 DTC normal CEL lamp flashes,or other codes of other errors lots possible. even 5 DTC codes roll out 1 by 1, can happen.
crank engine, over,5sec and release key only, see 41, for 42, BINGO, what failed, is known.
it only takes CMP good, ECU good , power to ECU good.
for ignitor to fire coil, and for sure a good ignitor.
