Hi all.
We I finally got a replacement for the suspect faulty crank sensor (only took 2 weeks).
Fitted it yesterday , and charged battery up over night as I'd managed to leave a light on in the car ..grrrr .
tried to start it this morning, and same old same old , engine turns over , no hint of firing,
Paperclip tests gave 89 and 31.
Checked and no spark at the plugs :-(
Suggestions ??
Im thinking a dodgy wire from the sensor socket to the computer thingy ??
Any other suggestions ??
Cheers
Diz

Was it an after market or genuine vauxhall sensor.
-
1st was aftermarket , the current is vauxhall
-
Code 31 is normal on a V6 when the engine isn't running.
-
89 is lamda sensor open circuit (afaik) cant see that preventing it starting.I would be looking at fuel supply.Relays fuses etc. Try a direct live feed to the pump to test it, see if it helps it start ?
-
Wouldn't be the immobiliser would it :-/

Update or should I say lack of update :(
1. Charged battery and refitted.
2. Checked the fuel pump relays, can hear them clicking when engine switched on ,
3. Checked fuel pump , not 100% sure its pumping , think I can feel a vibration , but didnt hear anything (maybe cause Im old? ;))
4. No spark at spark plug , checked the distribution pak think (by feel) non of the plugs or leads were out.
5. paper clip test shows 31 and 89 .
Brough a bluetooth OBD2 diagnostics module off fleabay, hopefully that will arrive in a day or so , might help track whats going on .
Someone suggest imobiliser problem ?? Is there anyway to check this ?? disable it ?? bypass it ??
If anyones got suggestions , please feel free to post , Im not very mechanically minded , but looks like Im going to have to become so :)

Thats a shame, your car isnt odb2 compatible

dohhh
errrr Happy Birthday dad :-)
-
the codes are normal when engine isn't running.
Did you reroute the wire correctly?
On my first Omega the battery going flat caused an immobiliser fault. code 145 iirc
-
Have you dropped the key recently the chip inside might be loose from the holder. :y
-
Nope Keys been nice and safe :-)
Q. How does the immobilizer work ??
how does it actually immobilize the car ??
and if the car is immobilized how could I tell apart from it not starting :-)
-
If the immobilisor is active .. ie its stopping the car from starting .. then the EML light will flash rapidly whilst the engine is cranking.

I realise this is for the facelift but I believe that it is the same for all omegas that don't have the old IR system
-
okay thgat kind of rules that out then , as the EML isnt flashing
