ok im ready,
your mech BLEW out the d102 trace, so im guessing he blew the FP relay transistor trace ?
or the transistor itself.? ( we will prove that)
measure the pink wire on the FPrelay
it will be 12vdc , goes to zero volts fast, then back to 12v in 3 seconds ever key on.

make sure the coil is not open. 10-40ohms.

we know the FP relay has power, MAIN is hot and CEL is hot so pump must spin.
if relay dont pull in then ECU is bad.
if relay pulls in then relay is bad or pump is bad.

we can find it with the voltmeter. checks.
if the relay does pull in, CLACK>
then see if pink black goes hot.?
if clack sound and pink dont go hot , the relay is no good.

if he blew up the transisitor , it is (many in one package)
IC11 M5262L

i have a spare and these are very hard to find. (i have canniblized board)
its a Christmas tree, i pluck parts and give away.

check the Pink wire next.

 

to each his own.
you can hot wire the fuel pump relay but that takes super car.

if the pump spins up with blue-black and pink-black jumped then pump is spinning ok
but if you slip kiss off ECU.
it dont take a big slip.

as any DR worth salt knows, first do no harm.

one more safer test
swap the 2 relays.
if main goes dead, relay in MAIN is bad. the first indication is CEL is dead.

those are the tricks and ways.
do as you feel safe doing.

 

sounds hard but just listen to relay with screw driver to hear.

key on , clicks or not.?

 

Hello Kick,
thank you for you patient support of my case.....

However, maybe in my previous posts, I didn't explain that:

1) Both relays are good, as I have swapped them, and each time
I switch key ON, the relay plugged in the MAIN "position", clicks correctly.
This is clearly understandable by holding that in the hand during key-switching. However, the relay plugged in the FP "position" does NOT
click at all. I believe it is a manner of drive signal from the ECU.

2) I am almost sure the repair shop guy (which is a young guy unfortunately with not so long experience as the old one does not get dirty hands longer), he hot wired the FP before my first help. So if we have more transitors blown I need your help to know what to check on the ECU, and if we can find replacements.

3) I doubt that suddenly the FP got damaged.

Maybe, even it is a bitter taste choice, it is time to finally give up, and buy a spare ECU?

What do you think?

Thanks alot.
Cheers

i concure. but i got confused as to when fp was checked before you fixed
D104 or after ?
ok if sure the coil on FP relay is good and that FPrelay still works in MAIN slot.
then ECU is still bad.

im sure you can pull it blind folded now ,right?
maybe even tad drunk , LOL

we can trace that trace (pray trace) B16 pin
i have naked board.
and the trace begins hidden under Conn B, Green
and touches C111pin8 then passes straight to IC11-pin 7
i will check more careful later.
make sure no burned trace by using OHM meter for continuity between those pins.

i have spare IC
in fact 3 of them, if need be. and are free,save postage.

 

Hello Kick,
of course I checked the FP relay AFTER I fixed the diode D102 trace.

I think it is time to search for a spare ECU, and maybe try later on, to fix
the current one, as it looks so new that it is a pitty to throw it away.


Spare ECU: ( 56b30 is the most common , used on most 91-95 8v 5speed cars here, hugely common and many TRACKERS here.)

I have found on web: these boards

1) 33920 - 60A70 = (I am checking the history of that, coming from where, if it was repaired and if it works - waiting for seller answer). [

2) 33920 - 56B40 = Did you told me in the past that this does NOT work on my car right? (not true, the 40 means A/T and will run ok on MT but B30 no good for A/T)
B30 MT
B40 AT

I did not find any 33920 - 56B30 so far. All present on web 10 days ago ar gone! Incredible....

Questions:

Do you definitely recommend board 1) right? I don't feel so safe as the seller does not give any guarantee between private. I dont want to buy something which will not work in the end.

Any other part number you could suggest for the seek?

Thanks lot.

it's an easy fix. (just make sure that the FP relay fails cranking, if it does (acid test) then that path on that pin is burned. a jumper may fix it.

most auto stores. (newly)

Questions:

why not fix it, if trace is blown. ? just open the lid and look , need photo of naked board. have it. ( and stick your machanics nose there and say, see what you did) LOL !

the ecu pn are on my dead ecu page.
see this link it was there all the time.

http://kick-fix.com/All-Pdfs/Part-nums-lists/all-pn-list1.pdf


60A ecu is a 89/90 vit/kick ecu, and ecu has no hand in spark creation ,due to standalone distributor. totally wrong for your car.

cheers.

see my comments.................

 

i butchered this up, pushing wrong buttons,fix it now.

sorry if wont ship to Italy.
search using only the full pn.
no space with hyphen

Hello Kick,
I am getting that most of the good ECU on web for sale, are gone all within the last 10 days.....very lucky......however I will keep searching.....

Meantime, as I have spent so much time on this ECU (and you too answering me), it is becoming a matter of principle.....this board shall come alive again..........so:

Could you please explain better from which B connector pin shall I check backward along traces? Shall I start by B15 or B16??

Which component do you think could be blown? .....Tomorrow I will get back the ECU and I will inspect it with my nose very close to it......

Thanks for suggestions.

Cheers
Eon

 

yes, all for that .
only takes minutes to do.

the pin is ....B16 to IC11-p7 (8 pins total and i marked pin 1 on right.)
use an ohm meter to check continutuity between those two points zero ohms!
if open put a jumper wire on the back from those 2 points.

 

Hello Kick,
I have checked the trace by IC11-p7 back to B16 pin. The trace is perfect,
indeed no damages are visible.

I double checked all traces under a strong light-magnifier.....nothing......no
signs of open circuit by trace damages....anywhere.....the board looks so new that is almost annoing that nothing is easily understandable.....

If you have other ideas....let me know...thanks.

Meanwhile I am trying to get in touch with someone selling spare ECU.

Thanks alot.

the transistor is rated at 2amps in ic11.
it can be blown to heck

acid test for IC11

• if the coil (FP relay) has 12v on one side. (main side, not ecu)
• and coil reads like 12-40ohms (in the realm, not open)
• and you crank motor?
• and you dont get .7vdc or less on the B16 line above (this transistor has ultra low turn on resistance VCE (sat) btw)
• and that trace is not cracked (still reads 0 ohms end to end)

all above true, then IC11 is TOAST.

 

above assumes harness is good. fprelay to ecu. and from same and main)

 

Hello Kick,
ok lets assume that the IC11 is gone.......where do I find that?

Do you think it is possible to get one of those somwhere?

Thanks alot.
Cheers
Eon

 

not sure but i can try pulling mine.
i will post back.

that is a mitsubishi part. m5262. not easy to find at all.

back later.

 

Hello Kick,
thanks alot for your help.

What do you think about this board?

Steuergerät Suzuki Vitara Cabrio JLX BJ.91 33920-56B70 su eBay.it Autoelektrik, Auto-Ersatz- -Reparaturteile, Auto Motorrad Teile

it is a 33920-56B70, will that work on my car Suzuki Vitara 91 - JLX 1.6L, 8V MT?

If I did not remember Rhinoman was saying that was a good one......

Thanks alot.
Cheers
Eon

 

we forgot what you had?

 

56B70 is what you have now.

 

Ok guys.
Then I will push to get a spare 56B70 board.

Reparing the one I have, how do I get a IC11?

Maybe you know someone selling it?

Thanks alot.

Cheers
Eon

 

im trying to remove one. now.
im slow, wift keeps pointing at eves. , hey mista. thems lites is not up. why.?

retire ppl are flaky.
i will try by 12 noon

 

Hello Kick,
so, you have a not working ECU for spare parts only?
If so, take your time.....no hurry......btw how much you
want for that?....

it could be that I will also manage to get a spare ECU meanwhile......
so my ECU will be a backup then......

anyway, thank you for your help.

Cheers
Eon

 

i will try now in few moments (sorry i forgot your ECU pn)
yes price is , postage only
I pluck the parts and give them away, im no scalper.
grin

yes, id not run any kick with out a spare (below 96)
and i have a 96 ecu for sale. just to lazy to list it on fleabay. my last ecu ,still whole.

they are cheap, i consider them free.
the first time its saves you, from a ton of labor and grief.
i bet the cost of the spare is free. huh?

bet is to get them before need. way better an you can bid low.
in panic you bid , buy it now.

there were $3500 new, then $1600 refurbed from dealers.
so $50 aint squat, no?

 

Hello Kick,
the body tag of my car is attached here.

Thanks alot.
