Xantia ECU reset after No:3 Injector Fault please help?

Post by shaunlfc1 »

Hi all,

An update from these two posts:

http://www.frenchcarforum.co.uk/forum/v ... sc&start=0



Basically I've changed No:3 injector, had all the others cleaned and tested, I've reinstalled the injectors new fuel, oil filter and oil, started her up and I've still got the horrible noise and the same "K" light on the dash.

Im sure somewhere I read that I need to reset the ECU after an error?

Is this the case and how do I do it?

The garage said the error code was 144 - "injection begin"!

Pulling my hair out any ideas anyone?

Cheers,

Shaun

Update:

Right with my multi-meter in hand I get 12v at the end of the injector sensor connector from the ECU and at the fuel pump/cold start solenoid connector from the ECU, but the connector at the crank sensor end I am only getting 2.5v. Tried it with engine on, engine off and injector sensor connected/disconnected, but still only 2.5v at the cranks sensor end from the ECU????

Is this the ECU being in a locked state and needing reset with a Lexia?

Also today I managed to get a 12v feed from the battery onto the cold start solenoid and SUCCESS the engine ran fine with no noise, so this proves the cold start solenoid is working and at least I can get it into full retard!

I will contact my local lexia holder and see what we can do.

So can anyone confirm that the ECU does need resetting?

Cheers all much appreciated!

Shaun
