31 on non running v6 is non conclusive....

You haven't left any connectors off have you?
I left the ICV connector off and got a whole list of codes and the EML light was constantly on, as soon as I plugged the forgotten connector in the codes and EML light disappeared :-[

31 indicates an in-correct signal.....so henc eits in-conclusive.
Does it start if you apply a small amount of throttle?
-
Thanks Daz for reply,double checked all connections everything is plugged in and also checked if there're 'home'.Mark,doesn't start at all,only time it did fire up was when i wanted something out of the Omega and needed to get into the boot so i connected jump leads to our other car and thought i'd just try it.It started and i ran it for around 30 mins till she was warm,switched off again,she did restart,tried again following morning and back to square one,don't know if that points to anything

Just tried your suggestion of light throttle,also just changed fuel pump relay and checked fuse,still no go,when cranking the eml does go out,is this normal anyway?
-
When i re-read the codes i still get 15,31 & 73,can these be removed so i can read codes again to see if they're gone...Wayne
-
Check ths DIS connector is home....
-
Thanks,will do that tomorrow,seems a shame to have it sat there,especially as i had to tax it last friday!
-
Been out to Omega this morning,had a scout around to make sure nothing was off,checked the DIS connector,that was ok,'waggled' fuses in both boxes,anyway she started!,run her for about 20 mins till she got warm,turned off and restarted 4 times,but back to square one again,5th time no go :(, is this crank sensor signs?...Thanks...Wayne
-
Had a look over Omega again this morning,still can't see anything obvious,could a crank sensor fail and not give a fault code...must have been a coincidence it starting yesterday!...any help/advice greatly appreciated...Wayne

Think i'm going to bite the bullet and replace crank sensor,anyone any idea how much they are at dealers,my brother who works for SAF (Mapperley branch) says he can get me one for £25+vat,anyone tried these or are they a no no?...Wayne

Should be fine.....and if it doesn't do the trick get it on ebay to recover your costs.
Make sure you route the wires as per the maintenance guide, makes it much easier to fit and keeps the wire away from the hot bits.

Thanks for that,starting to get depressed with it,keep repairing other peoples cars...and can't my own...lol

Did you check for codes with the engine running? Were they the same if you did?
-
Hi,yes,still got the 15 and 73,pressumed they were still logged because it hadn't had the 20 or so clean starts
-
I bought one recently £26+vat is it normal to have to remove p/steering pump to get access to fit, or is there an easier method.

Assuming you're talking about your 2.2, you can access it from the
top by removing the exhaust heatshield and the oil dipstick tube.
You'll find it about 2" forward of the dipstick tube. It's still a bit
tight, so you will need a universal joint or flexible drive for your
1/4" drive socket.
Don't forget to plug the dipstick tube hole with something before
you start removing the sensor, or Murphy's Law states that the
bolt will drop down the hole and into the crankcase. :)

Well come to fit the crank sensor today,had 2 problems,first one was i couldn't get the trolley jack under because i had parked to close to kerb!,second,i asked for an oval type plug fitting,opened the box and it's the square!,my fault should have checked,took it back and was told "looks like it's been boxed wrong" and "oh by the way oval is another £15+vat,not happy as i asked for the oval in the first place...lol
