g16a no injector signal, error code 14
#6

and engine floods.

in general
4 dead MPI injectors (noid fails and scope shows DEAD no PWM signals to all Injectors
causes. (spark good)
1:ckp dead, if ECU uses it, no ecu p/n told.
2: TPS TP pin stuck at 4v not 1v normal
3: no fuel pressure, 30 to 35PSI is normal , its in the manual,
4: cmp is not dead you have spark.

keep in mind these ECU are brick dumb, nothing on earth worse early 90s , OBD1 is dumb.
that means most errors even important are not reported.
14 is dead ECT

if the TPS is wrong , it only reports. dead and shorted,
if it reads too high it simple thinks you are doing the unflood cranking mode and is normal and no DTC for normal.
This TP pin, in modern jargon is Throttle angle.

if I walk out to my new jeep and floor the throttle and crank there is no injections, by design, same on all cars.
is the TPS at 1v? (the wiper arm on the TPS sweeps 1v to about 3.5v and never 5v. for angle.) if 0v DTC for that , if near 5v, DTC for that.
