Samurai TBI | No Injector Pulse

[fixkick]

Ok thanks for the in depth reply.

Yes TPS 5v good. Ground is good. 0Vdc at idle good. (Even installed a different TPS just to dbl check)

I have an actual NOID light testing set. Not LED. I assume those lights work ok for this?

Just want to clarify my next steps:

-I should remove the injector from horn and have it plugged in to the harness to do NOID NPN/PNP test? What does removing it do?

"this is true 1991 up, never on sammi." Are you saying on my 92 Samurai I can't do this test?

"as you can see R225 must not be burned open." I can't find this resistor on the board, do you have a pic showing where it is? Or I can post a pic of mine and you could point it out.

Thanks for helping me figure this out!

sammi, what is sammi here? IDK

this is sidekick /tracker forum not sammi
but some sammi's run the tracker engine /harness and ECU and all EFI parts.


what ECU do you have there, sidekick ends in 56B30   (means sidekick + 8valve+ TBI + 1991-95 , + stick shift 5 speed)
what ECU do you have. I sure can not know that,  these old cars can be hacked up 100 of ways,,,,,,,
consider I can not see your engine bay at all.


the sammi has no pnP transistor,
some have  hidden injector huge resistor block, sammi EFI is very very driffent that sidekicks, or vitara or trackers or sun runners.

is this a FRANKEN SAMMI (or franken KICK)? IDK.

here ours is in all its glory

60axx ecu is 89/90  very different.

r225 for Npn Q102  this resitor is HUGE, 5 full watts huge. thumb sized and is  right next to Q102, white on mine.

1/4" wide, and 1 inch square/ sized  seen here clearly
Q102 here, then r224 small blue. the then white monster,  R225 , and may cover its ID mark so big. sorry  0.27 ohms ( one quarter of 1 ohm) reads as short sure.)
