Hi everyone,

I am in Australia. The Australian forum for 5th gen celica is basically dead. So I am asking for help here.

Will an ecu with leaking capacitor cause engine stalling issue ? I believe code 14 is ignition related.

I have removed the ecu and opened it up. One capacitor has definitely leaked.

Cheers

I had the same problem and each time the time length got shorter before a stall. Threw a lot of $$$ at problem fixes because it seemed heat related. When the engine would warm up it would stall. First time was about 20 minutes and then in a few weeks it was about 3 minutes before a stall. I even replaced the brain....should have been mine :)
The problem was a bad internal distributor coil. Not to be confused with the igniter. This was on a 1991 version of the 5sfe where the coils are actually in the distributor. If you have a ohm meter you can check these coils....search the net for the procedure, it's pretty straight forward and simple.
There are two internal coils and both should read 170 ohms. if one is bad your stall problem will happen.....at least that was caused mine. I bought a dizzy from a website that said "this will fit your car". It fit but was totally wrong junk, not saying where it was manufactured (guess). I finally bought a guaranteed rebuilt OEM one from NAPA, around $300. US and never had the problem since.
Hope this helps.
Cheers mate.

Forgot to add. That leaking capacitor picture is not good. There are several sites that remanufacture or repair your computer for less than I paid for the dizzy. If you think that would help I'll post where I got my remanufactured computer from. Cost less than the distributor with free shipping.

Hi,
I've the same problem in my 3s-ge.
I didn't saw anything similar inside my ECU, but will search again.

I've changed a new ignition coil, used igniter, used vacuum sensor and a new CTS temperature sensor, but I only achieve a faster stall.

My problem began just 2-3 miles away after refuelling, so i'm thinking in empty the fuel tank and refill with other fuel.
It was a well known fuel station and 98octane fuel, so it's confusing.

I also think it can be a worn fuel pump, or like Sea-J says, something with the distributor or position signal sensor?

Please st184newbie let me know if you find solution or anybody knows what can be.

Thanks and regards!

Hi,

Thanks for the reply Sea-J. I am in Australia so postage will probably be more expensive than the part. I have sent the ecu to get it repaired. Hopefully it will fix the engine stalling issue. I have tested all the connections going to the ecu and ignitor and it seems within spec. I got a new oem distributor and ignitor. The fuel pump was replaced because it died before the engine stalling issue.

st182, did you see the check engine light flashing when your car stall ?

@st184newbie after the engine stalls does your Check Engine Light not come on with the other dash lights and only when the Check Engine Light comes back on then the engine starts.

If I remember correctly. After the engine stalls, the check engine light started flashing. I didn't really take notice of the other dash lights. When I tried to start the car, the check engine light will keep flashing and it will not start. I had to disconnect the battery and wait for a while then it would start but t would stall within 5 - 10 minutes. It got to a point that it did not start at all.

Hi!, finally I rechecked my ECU for third time and there was a capacitor leaking.
Replaced it and now the Celica is alive again.
Take your ECU to a TV repair or replace the capacitor yourself. Mine was a 10uF 50v that I could get from an garbage circuit board.
Regards!

That's very good news. I took my ecu to a shop that specialise in ecu repair more than 2 months ago. It is still there:(.
