Samurai TBI | No Injector Pulse

[fixkick]

OK this car is TBI and only this car has this class of TBI , and not even like any MPI 4 injector or 40year old chevys with TBI not the same.
no shops know this car this TBI nor do they even remember OBD1, and the lack of scan tools on this car, suzuku sucks here. that rule.

This TBI drives both sides of the Injector (2 transistors)
and both must be good or the engine dies, or floods,
the work as team to get the PWM correct and  nether transistor is optional.

it is not  just one transistor per injector like 99.9999% of all cars on the road it is 100% unique to this suzuki. the TECH.

the transistors fail for many reasons, here is list. to make it simple. (more) (all other input pins to ECU not wrong)

• injector is shorted (coil)
  
• wires shorted to injector
  
• alternator went mad, (reg) and hit 20+vdc boom and wrecks transistors lots.
  
• overheated,  transistors,
  
• overloaded, see alternator or shorts.
  
• ESD damage (bad handling)
  
• lightening hit car, boom. random things dead.
  
• ECU came from other car that was stressed badly there, (history matters)
  
• transistor loose on heatsink.
  
• transistor thermal grease old and cracked, causing overheating of same.
  
• wrong transistor put in and shorted Collector to ground then causing other transistor to overheat and engine wants to flood badly.
  
• R225 open only so transistor can not work at all.
  
• some one wired in a silly ALARM box to car or  omg remote start box to ECU and blew up very rare parts. here.
  
• some one (not you) hotwired the injector. (seen this vast times,)
  
• I hope I got them all.  but there is on more (luck bad, age failure or pure  entropy failures or part was weak to start.)
