Hi,
I have checked the forum and suspect I have the answer, but before I ask the local garage to get stuck in, just wanted to check.
Symptoms:
Car not starting - just turned over, eventually caught then
EML came on & at about 30, just as I was about to go over a level crossing, the car died - bloody 'ell that was not fun as the car turns into a 30mph brick! :o :o
After an emergency pull over next to the crossing, the car would start then die if a) got down to 1000 rpm, 2) got up to 4000rpm. Got it back home after a few more cut outs.

Therefore my assumption is crank sensor fubarred - would the symptoms be consistant with the assumption.
if so I'll tell the engineer to change it / the lead.
Thanks
Alan

19, yes, that will stop it.
Change it yourself, takes 10 mins, 30mins if you can't get to plug without lifting plenum or removing scuttle.
Don't run cable same way, they is a guide in Maintenence Guides showing an alternative, better way.

Have changed the crank sensor. The car now starts. Unfortunately I still have some problems and would appreciate any pointers.
EML stayed on after changing sensor.
Driving, EML turns off, turns on a few times, then, whilst off, car looses all power, effectly goes into idle, you loose speed, then the eml comes on & car responds as normal (note I haven't driven it far so don't know if the car will keep repeating the above, but it does happen every time I drive it). I assume its going into some 'limp home mode?' and then dropping out of that when the eml lights up.
did clip test late last night, I will try again tonight as I think I may have misread it, looks like (after the 3 12's) 144 and 145 which are not on the list.
Does the description above ring any bells on where I might look next?
Thanks
Alan

144. No immobiliser signal recived - Faulty unit or break in wiring
145. Incorrect immobiliser signal received - Faulty unit or break in wiring.
Is it possible you may have nipped a wire when fitting the new crank sensor?
Any flashing EML when starting or before starting the car?
-
Don't think we caught anything, but I'll double check when I get back from work. I'm still not confident I read them right as it was rather late and as I had to leave at early this morning didn't have time to recheck.
The EML does not move between on & off before the car is started up and stays on until the car has run for a few hundred yards. Then it moves from on to off at a fairly slow pace, like on for a minute of 2, off for a short while.
When turning on the ignition the EML light is lit up.
Thanks

Definitely give the codes another read then. I doubt the immobiliser is a problem anyway as you probably would not be able to start the car. Did you use a genuine Vauxhall sensor? Time and time again people have problems when they use generic sensors.
-
Is the sensor you bought a genuine Vauxhall one, I have heard of a couple of none genuine ones being faulty from new.
-
Yes, a genuine VX part was used. Also checked the part numbers of the new one and the one taken off - both the same.
