Was eml flashing though?

Op only mentions constant flashing from spanner light when doing the pedal trick...? Which means no codes.

Not convinced there was a fault at all tbh. Just grumpy starting.

But happy days.

Cant remember if it was flashing EML or Spanner when it happened to me TBH Chris.

Just constant flashing when doing pedal trick.Started immediately after doing Zirks procedure though.May have been a coincidence,but it was a hell of a coincidence if it was. It refused to start for previous owner more than 6 months ago and has repeatedly refused to start since.
Anyway,clever dick or master of witchcraft,who knows,but thanks Zirk.
I can now test everything on the car works ok before ripping it apart.

And thanks everyone else for trying, aye Albs?

And don't forget my lambda sensors!

Im going to start dismantling this car in the next few days,but would ideally like to get it running first.
It turns over,sounds like its firing occasionally,but wont start.
Pedal trick shows spanner light constantly flashing (is that immobiliser issue ?)
Known good crank sensor fitted.
Petrol is being pumped up to the fuel rail ok.
Not going to spend a lot more time on it,but am curious.Normally petrol + good crank sensor means they will run ime.

If it is, you need to go through the motions, ie Key out off ing., open door, lock, un lock door key in Ing, again all with the right Key and Chip otherwise it wont start even with the correct Key and Chip.

If that makes sense.

That's not right. No amount of sync'ing a key like that will make the chip in the key talk to its immobiliser ECU

The fact the car has started is shear coincidence   

Its not sync'ing, its a restart thingy, if there is an issue with the Transponder Chip talking to the ECU then it will refuse to start, even if the problem has cleared itself, untill you go through the Lock up and Unlock motions.

Ive had it before a couple of times, and thought it may pay off for Albs, which it seems to have done. Not to say it may not come back and haunt you though.

I'm still sure it was a fluke  . As fas I know, no communication with the immobiliser won't stop the car from initially starting ....... it just stops very soon afterwards, or at least that was the case with an Astra that SWMBO had when I had a new key Tech II'd for it.

In my experience of the FL Migs, it wont start, just turns over with flashing EML.

Example, 2 keys in your pocket for the same Car, one has a missing Chip, try and start with the missing Chip, wont start, realise what you have done, pull the working key out of your pocket and try and start, still wont start even though its the correct key, go through the lockup procedure, car starts.

When Albs mentioned flashing EML and not starting, thought it might be worth a shot. 

Chris's logic works here I think.  I bought this car as a breaker several months ago, and I now seem to remember the previous owner said he had lost the keys and had to buy a new key for it.  Albs will confirm, but I'm sure there was a card with the key code on it with the paperwork for the car.  I'm now thinking that this could have been a contributing factor for him wanting rid of the car.  When I went to collect it, the battery was completely flat, and we tried for a good hour to get it to start with no success. 

Anyway, witchcraft or not, a good result!

There is no connection between the Immobiliser ECU and the ATWS ECU (nor between the fob and the transponder), thus this procedure is either fluke, or doing something odd within the key/ign.

But whatever, works now, and I suspect "for how long" is not a relevent question as its being broken.
