welcome , Malcolm.!!!!
a custom car, and that is always a complex topic, what parts, what years, fitted where, and missing parts, omg.etc.
a 1997 SAM-KICK i think it really is. tells it all if im right.
im totally confused
87 sammy, ok , that dont matter
what matters is the
what is connected to the 97 MPI engine, its got 4 injectors, how can that run on a TBI system? even the manifolds not mix....!
my guess? is this is a full 97 MPI setup , right, all parts.... (most ) harness for 97, engine, manifolds, sensors , injectors x4 , etc.
to diagnose any problem we need to know what engine, and what EFI you run, even the ECU part numbers.
after all the ECU runs everthing, there. spark fuel, idle , all.
even bad idle air supply cause the engine to flood.
that is 100% legit, the new cars all have the 2 lines now. opr guide.
1: if engine flooded, crank 100% throttle (WOT) this cuts fuel 100% and clears the flood with vast fresh air. (TV air)
2: if engine is hard to start, not flooded, at 5% throttle to help.. they added this line because some times the (gee common) the ISC sticks closed.
the PCV+EGR gas cloud of death gunks this up.. and more...
900 idle is wrong hot 850 i s max (if you have a real tacho, or scan tool, if dash meter, well 900 must be really 800 as this gauge lies easy)
1500 is normal that is IAC doing that. until 150F is crossed (water temp)
fuel pressure is good. all that. and you skipped nothing , but balance testing. of injectors using same tool.
By IAC you mean the ISC. (back in the old days suzuki called them both IAC, kinda silly that, so now uses the correct ASE names)
no need to argue names
or use IAC-E (electric or IAC-T (thermal)
the hards starts, im my opinion (ECU scanned yet, that is first) all 97 scan with $10 tool. used one yet?
are
iSC not opening fully , with warm start or the IAC is not opening;
the IAC must be open full cold. (mounted below the TB it is) wish you had said where your IAC was located.
the ISC is electric, and is mounted on the left side of the plenum. its easy to test. ask. both are.
the coolant sensor has 2 pins gray-yell is ground 0vdc.
the other pin is pulled up to the ECU internal 4.7v supply
my guess s the Red-yell wire is at 4.7 (4.75 to 5.25v is spec on your good supply but how ever
the ground is open on the ECT and IAT.
That ground is called ECU super quite ground. and is just a buss bar in the ecu to real ground/
so if i knew what color wire that was.
and the ECU partnumber, well, this gets more easy.
must be 5speed manual transmission
with matching ECU.
the 97 that ground wire can be brown on some markets.

the scan tool will barfing DTCs for that. for sure.
but most sammy owner like this , connect up every thing but the 2 DLCs
DLC1 OBD2 scan port
DLC2, the very much needed timing freeze jumper to get timing right. did you>?
a dead ECT causes flooding
because of 2 reasons, 1 it can thank its in alaska, and that be -40F max cold and floods
but worst happens this failure causes FAIL SAFE and that cuts idle controls , goes rich as a pig, retarded timing, and weak starting air (ISC limited)
why not get $10 tool and see what else fails , i bet lots.
the ECT reads 300 ohms hot.
the ECT ground is 0v
the ECT hot wire is .65v hot.
per my ect page
http://www.fixkick.com/ECU/temp-sensors.html
set that table, i calculated all ECT voltages, Its not in any books,, just here.
boy will you be amazed when all this ends, like 2 times more power....... amazed....
failsafe is no place to be
is this 97 , even missing the CEL lamp , yelling SCAN ME?

LOL !
good luck and glad to help. i love, samokicks.
