ok no injection
other that bad ecu
bad power to ecu.
that leaves 2;
1: TPS signaling wide open throttle WOT during cranking.
2: Spark feed back at spark suppressor module , brown wire open or missing.
wot at crank = UNFLOOD mode.
this can happen for 2 reasons, bad TPS, or set wrong.
or
open ground to tps.
wish youd say what motor, 16v or 8v , MPI or TBI?
total diff syst.; but above true on both.
one more very nice test.
go to DLC connector next to battery (oops missing)
place DLC diagnostic jumper ( oops same)
then crank motor for 5 to 10 seconds
release key (DO NOT KEY OFF)
ecu will blick out CEL code 12, 41 or 42, (oops missing)\
41 and 42 are missing spark read back or bad CMP signal (tacho as other said)
the ecu knows whats wrong and you car has no CEL so you can listen to it tell you what is wrong.
install DLC, install CEL lamp.
note getting spark that is OK , and getting the brown wire read back of spark is 2 diff things.
the spark read back is back EMF from the coil primary , about a 40 to 80volt spike.
if it dont make it back no injection.s
this is for crash safety ( no Read back OR no CMP , tehn no fuel , though no crash and Burn)
that is a mandate. so not unique to suzuki.
