sure , those are the caps. there are a row of transistors there, some are injectors others are a regulator;.
is that your ECU or a stock photo?
these are old cars, and they get lots of failures, the ECU is just one part;.
would you like to do real diagnosis or just guess?
engine have over 150psi compression?
so engine starts then floods after a time. ok, we have 2 symptoms now, floods and stalls.
CHeck engine flashes? well does not this car have a fuse box fuse marked diagnostic, and if the someone forget and left it there?

see that, and if there, flashing is 100% NORMAL, its in DIAG mode. so what is the flash code, 51, or 23 or what? code 12 is NORMAL.
false pause, flash flash , longer pause , repeat. 100% NORMAL
so?>???
if that photos is yours , is it, those brands of caps are not know to fail, only the black rubycons love to fail. all can but not like Rubycons.
did you make sure that the injector orings dont leak. ?
off the air horn, look in the TB air horn and crank and cut the key 3 times, as you cut the key the driver tells you, IM CUT and you make sure the injector
does not leak. as key goes OFF, the KEY off kills ALL INJECTIONS in 1/1000 of a second.
if the injector tip leaks that is one failure call that x
if the injector rings leak , they are bad.
if the injector leaks, we then must test the injector drivers,
the ECU can not inject correctly with fuel pressure at 60psi
so we check pressure, oop, its wrong
and test the fuel pump regulator.
are you lost now, and only hope to fix cars by guessing, its near impossible on cars. for sure old. some have or 3 failures, the drivers ignore.
but you are correct. lets see if the ECU is bad, i have 8 tests on my bad ecu page, ill recap them.
1: fuse out (diag above) I key on the CEL must glow. steady. not flash.
2: start engine, the CEL goes out. if not , it wants to tell you why, so that is next.
3: we put back the fuse. (diag) and we key on, the flash codes now are called fail DTC error codes. there can be 1 or more errors. flashed 1 by one
4: ok i get 12s that means its happy.
5: so I install the Diag fuse. and drive, i get 12s, all the time, then at 62 miles the 12s changes to something else. BINGO?
6: or the ECU will not glow ever, or it glows but will not flash , on demand (diag fuse means demand) (not you.) next
7: The Codes 12 abort, its flasing 12s or some other code and it aborts, does not finish the code, that means the ECU crashed, (see bad corner cap top left)
8: ECU is in back up mode, (no CEL glows ever)
9: ECU is in Failsafe mode, this is normal mode, it means the ecu sees and error and drops to this mode, and driver of car fails to see oh my, its flashing code. 32
fails safe is called limphome by others.
in limphome the car will burn tons of fuel, 15mpg or worse. forget that, learn to read the flash codes then ask for help.

VN country but what does the engine bay fire wall tag look like, here is one.
the hard part of testing the 90' injector (TB)
is this ECU will no turn the fuel pump on,at keyon, making the leak tests harder.
to do it right, it takes 2 persons.
on at key
one staring at the injector tip.
http://www.fixkick.com/fresh-air/Slide_S...age_6.html
at key off , the inject must HALT all injections instantly, or something is wrong.
The other test is the injector leak down test, (ask)
the driver.
so use an ohm meter and find the 2 injector pins B8/B17
and using a simple continuity check find the 2 transistors like did 91-96
here is the schematic
http://www.fixkick.com/INJECTORS/89/89-90schem1.jpg
B8 and B17 pins>?
we can in fact use a simple NOID lamp to test these driver. ask. (its on my injector page)
btw 2
this ECU does not make spark'
only the DIZZY (distributor makes spark)
so if its bad, the ECU will inject too much fuel, and it will stall, (cant burn fuel with no spark so its not the ECU fault at ALL)
what if car stalled because spark fail, and BTW 3
the ecu will flash a code, Diagfuse inserted) driving and car stalls, it will flash. code 41, so long as you dont turn the keyoff.
code 41s are rest to off, key off.
tricky but you need to know that. to find lost spark.....
the ecu cuts fuel with all code 41s, by law, (no crash and burn rules)
so 41s rule the world. here.
The ECU can not see actual High voltage spark only the ignitor, kick back pulses. (coil is working on primary side)
these old cars are infamous for bad, caps.(ECU) and bad VR /ignitors in the DIZZY.
lets id car first.
