Omega General Help / Re: Re-tensioning ECU terminals?
« on: 28 August 2012, 03:54:27 »
Update: Not much progress, the auto-electrician reckons it is a faulty key, and I only have one, so they are trying to get another one through second hand dealers :-\

I don't think this is possible as the last garage that got it started for two months didn't do anything to the key. ???

Well, it's been towed to an auto-electriacian, so I'll let you know the outcome if anyone is interested.

Thanks guys, yeah it turns over fine, just won't spark up.

I guess the ECU tampering was only a short-term solution and maybe replacing the crank sensor is the long-term one.

Does anyone know roughly what it is likely to cost to replace it?

I just read this on another forum :'(

2.5 V6 models a nightmare, CATS fail wholesale (cats need back pressure testing plus testing with four gas analyzer).  Engines are prone to cylinder head failure between bores (they do not pressurerise coolant as a rule, so leakdown test thru plug ports, only conclusive method of diagnosis).  Cambelt replacement vile job, most small independent garages just won't do it.  Avoid any form of major electronic diagnosis like the plague, motion sensor faultcodes common, even when sensors show perfect waveform on scope and are working perfectly with host wiring in excellent shape.  Piezo knock sensors on engine block suffer from bad earths and component failure (very difficult to get to and backprobe to prove function with scope).

It's a 2.5 V6, seems to have come to NZ from Japan.

The previous mechanic's e-mail read this:

There was no actual fault found, but the engine started going after the engine ECU terminals were re-tensioned.

Omega General Help / Re-tensioning ECU terminals?

I have a 2001 Opel Omega V6 auto stationwagon and it goes fine except that every 2 months or so it just won't start. The last garage got it going simply by re-tensioning the ECU terminals and it went sweetly for two months after that. Now, exactly the same, no spark but battery is fine.

As it happened at home (luckily) I was hoping to get a mobile mechanic to re-tension the ECU terminals or even have a go at it myself, seeing as it did not take long for it to be remedied last time.

As an aside the Engine warning light kept coming on and the previous mechanic thought it was a faulty knock sensor, got a new one sent from Australia, was a total waste of time and money. In the end the mechanic simply disconnected the Engine warning light bulb as there was no fault detected with the engine and so on.

Anyway, where is the ECU located and how are the terminals re-tensioned?

All help appreciated. :-\
