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.

[dizaster]

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

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

[hoofing it]

Have you dropped the key recently the chip inside might be loose from the holder.

[dizaster]

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  :-)

[Entwood]

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

[dizaster]

okay thgat kind of rules that out then ,  as the EML isnt flashing
