Samurai TBI | No Injector Pulse

[fixkick]

our  8v is not like that at all . TBI/SPI.  100% unique to this car  TBI unlike any other TBI on earth in fact.  2 rail driver, see that, sing UNIQUE.
I test mine using a scope
nobody sells used or better reburb samurai ECU now, for sure not suzuki.
all these old ecu love to fail for top reason bad electrolytic caps,  the VRMs too go nuts with noise on the inputs to the  VRM voltage regulators models.
there are many failures beside this.
1: all inputs to ECU must not be wrong for sure  CMP and for sure TPS TP pin (1v good not 3.5v up) TPS idle switch pin at 0v not 5vdc.
2: caps not bad.
3: injector not shorted or  its 2 wires. nor open wires. nor shorted to ground.
4: r225 (different id on sammi) not open. 
5: snubber D112 not open or shorted, if open back EMF (inductive kickback) signal kills Q102 dead.
6: both transistors must be good and pass super beta (hFE) tests.
7: both transistors must not be metal backed, or C is shorted to metal heat sink and boom, dead.

many cars these parts are blown to hell buy doing hotwired HaCKS. (AND NO CPU SOLD NOW.. IS WHY)


this is sidekick 91 -95 , not sammi  ecu. but is close. names different. on ID.
