looking for 3s-ge rev3 97-98y ecu

[pasqual]

short story:
I have celica st202 98y (europe ver) ..I swap beams...

Now Im swaping my old engine 3s-ge rev3 to my firend car....

problem is : engine starting and after 2s die ....

YouTube - Ga?nie

I checked all wiring etc (tested what was possible)

and after all I figure out can be ....ECU immobilizer ...

I have confirmation europe version of ecu have immobilizer

I need decode ecu ....
or find out ecu ..... the best will be jdm

maybe some one who did swap to beams have still old 3s-ge rev3 (94-98) ecu ...

any other idea YW....

What are you swapping the gen3 3sge into? Did your friend's car previously run an afm instead of a map sensor? Seems to me like you're not getting continuous fuel flow. If you want to check, if you still have a diagnostic connector, just bridge Fp and +b.

I don't think it's your ecu.

[pasqual]

his old engine is 7afe have MAP sensor too ...

I tested Fp and +b. already ..... I tested MAP sensor too signal output correct ...

[mr220v]

Did you verify that the fuelpump was running?

This seems a whole lot like an interuption in fuel.

Here's another idea.

I was testing a 20v a while back, and was getting this same run for a second, and then cut out. Turned out that I had a few bent pins on my igniter from forcing the not quite compatible plugs together. Are you getting a good igf signal?

yes pump is running

how check igf signal ???? if is correct ??

[mr220v]

All you have to do is check the codes like you normally would. It's code 14.

[pasqual]

no errors code ... this is the problem ..... ecu say nothing

when I disconnected temp air sensor for checking ....code on ecu was correct ....

[mr220v]

I would put 12v directly to your fuelpump to ensure that you're getting fuel.

I second that! Can you hear the fuel pump when you start? Worth a shot!

yes.. fuel pump seems be OK....

no idea what else can be ....

next 2 days I should have jdm ecu ... so we will see ..

[mr220v]

Just for clarification, you put 12v directly to the pump and tried to crank it at the same time?

I don't doubt that the pump is functional.

I will do it in Friday .. now Im far away from this engine 300km ...

[pasqual]

ok .... after test with jdm ecu there is error code 14. IGF ?? ...

Ignition Signal

Condition:
1. Condition: IG ON
2. Symptom: Open or short in ignitor power circuit
3. Term: 1 second or more

Inspection Part
-Wiring and connector
-Ignition Coil
-Engine Control Computer

That said i'd be checking all the ignition wiring to make sure its not earthing, and that it's all connected up.

[mr220v]

Yup, code 14 means no return signal from the igniter and can cause this exact problem.

Since yours runs for a second, I'm thinking this is one of a few things:

-bad igniter
-incorrectly wired igniter (on the ecu plug, or on the igniter plug)
-broken igniter wiring (igf is pin1 on the igniter plug)
-damaged/bent igniter pins (this can easily happen if your trying to use an older style igniter with a newer style plug)
-bad ecu

So, those are a few cheaper options to look at before buying an ecu. Look for damaged wires or pins on your igniter, make sure you get continuity from the igf pin on the ecu to the igniter, and if you have a spare, try a different igniter. Nearly any similar looking igniter will work, though some have problems past 4k.

[pasqual]

I compared both ecu pinouts (euro/jdm) IGF input is on different pin ..... So I corrected it .. and engine is starting correctly ....on jdm ecu


PS: funny is Im away 300km from this engine .. just remote work (onsite hands/eyes)

[mr220v]

I knew it would be something like this.

Drive it around a bit and check codes again to see if there are any other differences in pins.

Say which one is the coil trigger wire bc im trying to hook up a MSD Digital Shift Light but can't find the proper trigger wire for the GMR pick up....
