I've been having a lot of trouble from my gti 6 lately,
The ECU stopped working so i ordered one from RichW; put it in and it worked fine for 20 min. before it stopped!
Now we can't get it to start, there's no signal to the spark plugs or the injectors.
do you have any idea what could be going on ?

We put in 20 L of fuel, locked and unlocked the car etc. Everything else is working alright Dunno

Anyone have any ideas ?

thanks !

samuel

Crank sensor sounds like it could be faulty. Yes

Does the fuel pump still prime when the ignition is turned on? Unsure

Imobiliser issue??
Mine was fine one moment, pulled up to put fuel in and it wouldn't restart.
Turned out the ecu was Fooked and kept locking ecus

Solved it with another ecu and removing the immobiliser

If the fuel pump is priming with the ignition on, then the ECU is supplying it with a signal and it's not an immobiliser fault.

    Wrong - the immobiliser does not cut the fuel pump - it cuts the injector and coil pack driver output Smile

    Samuel,



    What was the reason for failure of your old ECU?

    The ECU I supplied has been professionally unlocked and de-immobilised, in cannot lock again. Ever.

    Depending on the reason for your old ECU failing, it could be an electrical fault that's causing ECU damage and failure, it could be the crank / cam sensor, or it could be the multi-fucntion relay behind the battery box.

    Did you want to send the ECU back to me? I can test it.


    Regards,
    Rich

    Fair one. That correction actually makes sense in relation to an issue I had. I 'unlocked' two ECU's from breakers and kept them spare for my 205 GTi6 conversion. When I fitted one and tried to get it started I had no luck at all. I removed the fuel hose and was getting fuel, but wouldn't start. I tried the second ECU - fired straight up.

    I can only assume I must have failed to remove it correctly to unlock it as with another ECU it all started up fine so it must be a fault with the ECU alone. Do you still buy locked ones Rich?

    Yeah, that all sounds about right.

    Yes, I do - you want to sell me some?

    Alright, i've just spoken to my mechanic, he's going to check the relay and make sure that's working; the crank sensor was changed yesterday so thats fine.
    Also, i noticed when i got the ecu that it was a rallye one ? that won't make a difference will it ?Dunno since I've got the gti6 ? also, the mechanic is wondering how you managed to unlock it because it doesn't seem to have been opened lol

    thanks again for your help Smile

    A Rallye and GTi-6 ECU is the same so there will not be any difference. Wink

    As for opening it, I guess Rich made a professional job of the unlocking and it still looks original.

    Have you tried ringing the two guys off that advert for advice?
    They should be able to guide you through it.

    Agree with Rikky, would be interested to know what the cause was. Yes
