yes, know it well i had to sail in it for months, curiosity of USN. (on a small ship) 25ft seas...... (even scaling masts in freezing rain, with no PPE!)
great progress.
is this car tuned up?, cap, rotor,wire set,spark plugs (at 0.028"gap 0.7mm), filters? this decade,? if not?, it will not like damp. (or be fickle.)
suzuki ground just plain suck. they use body for ground where no sane engineer should, crazy, its ok at ecu for noise earth ground but not power.
and after lots of AGE and road salts (they salt road there, when sand dont work IIRC)
the salts kill those connections.
the other ecu died from acid spill, as all 89-95 do. (usa and canada, other countries some have totally diff. ecu)
the caps leak, the acid spills and if not cleaned it eats the copper to death, and can even burn up.
there are not to many 1990 around, and they are unique, with there own harnesses, i dont have ground names for that year.
the distributor makes its own spark too. that year, like 60s car but with electronic ignitor inside, and with advancing weights and vacuum advance.
it too must be grounded well.
there are only 2 ways to fix this,
1)inspecting all critical grounds for EFI
2)or catching it fail, and why.? (lost fuel?, lost spark? and who caused, it, (ecu lost power? , ecu inputs wrong or ?)
The ecu does all in its power, to start the engine,(it cant help dizzy ) but can inject based on real ambient temperatures, real good.
this car has only 1 injector, so if it cuts out , it will not run, or start.
just finding if it lost fuel or spark is key
my guess, its its fuel. based on test fuel always works, a very strong Evidence.
so what kills fuel.
only 3 basic things, ECU, inputs to ECU, and the injector.(and fuel pressure good)
but not we can't trace working. if it runs, we cant fix it.
ECU caused it. is my guess.1
if it dont start, we insert the diagnosic jump in the DLC, or fuse box (as found) and crank for 5 seconds
its flashing 12, now, i crank and it flashes errors. 41 or 42 and others, if it flashes non 12, you just found the problem.
if it dont inject then make sure the TP pin on the TPS is near 0-1v and never 4 to 5v, if at high voltage the ECU sees this as CUT FUel. (a feature) and is not an error but of the GROUND wire to TPS opens ,it will cut fuel cranking, called, super secret unflood mode.
thats it.
unless flooding, when and engine fails to start, and spark is good x4 , we check for flooding, and set throttle wide open with right foot and crank it clear.
its and 8v, you can look at the injector directly, when not starting, you look and it injection or not? this is what we do first. and 10x that for if spark good and test fuel passes. the horn/pipe comes off and is only fresh air tube, it's not metered air pipe like 1992 MPI engine.
if it fails again, we only need the injector eye ball, if it passes that test ,the fuel is bad, or spark bad, or is flooding.
are those fresh spark plugs. gapped right at 0.7mm and not every using out of the box gaps, as it will not run with that,
