Samurai TBI | No Injector Pulse

[fixkick]

injector load resistor block  , i think (10 years remembering) is on the fire wall or from there to TB.
resistor coupler.
i do not remember for sure where it is but , my be for the injector

no problem there , the sammi is welcome here and many things about it are near same both car  8v.
just a unique ECU and , fast idle speeds.
and maybe that hiding resistor, outside ECU)
the geo metro  uses 2.5ohm resistor block FI injector so is common on some suzuki. but I think it has 12 ohm injectors, not 1ohm on the metro.

The Metro injector resistor block is on the top right of the firewall, looks like a heat sink with a yellow clip attaching two white wires coming off of the resistor to a white wire with a blue stripe and a yellow wire.   
2.3 to 2.5 ohms was measured across the resistor , by one person.
If the resistor burns up, all injections stop.  Infinity readings, is bad in all cases. (due to no current flow)

if the ECU has wires on A20, this goes to some resistor .  gray/white(stripe)

usually the 12ohm injectors (HI Z) use a resistor. (so called peak and hold)
the 1 ohms  have no resistors and do not hold, they are PWM cooled, modulated to they can not overheat,  (like your 1991 does) aka,  Low Z injectors.
