If you did the paperclip trick to get the flash codes up do they read as DTC's then on VX's ? Thought it needed to be cross referenced like the troopers but might be wrong .

Not that up on petrol VX dtc's as more a diesel man but OBD stuff but I do get on with and I still think you need a tech 2 plugged in and to post the live data screen readings on here .

Just stuck my tech 2 with the VX card in a 99' petrol corsa with no faults and it reads it just like doing 3.0 and has a lot on testing the immobiliser. Same thing when I tried the Axone 2000.

The paperclip test flashes the EML light a certain number of times which you count and that will give you a series of four or two number codes (depending on ECU) that can be cross-referenced with a chart to give you the fault codes stored. I would be interested in seeing what an Op-com live data readout would give as well, but I neither have an op-com or live nearby.

A long shot but my Monterey Petrol recently would not start after tidying tow bar electrics Evil or Very Mad

Found a black/red wire broken near tail pipe Surprised

I thought wire was fuel pump however club member Rhanagar suggested

"More likely a feed to the brake lights. Some cars will refuse to start if they dont work".

I said it was a long shot Exclamation

)

Fixed the black/red wire and and normal service resumed Rolling Eyes

l

Good luck

Ed

if its the immobiliser then the EML will flash when you try to start it - i would actually ask does the engine turn over ?
The vauxhall immobilisers aren't designed to stop you moving your own car but rather someone else
if there is a fault it'll let you bump start - then the fuel pump gets its feed directly from the alternator rather than through the ignition
this only happens in a few cases where the immobiliser has messed up almost a get you home /to a garage help
You will get the EGR code if the engine isn't running too - along with crank,cam and numerous other sensors which will report no movement to the ecu
cheers

HMMMMMMMMM. Much oddness!

Auto electrician with car now. He's saying it's not an astra g, but an astra f. Also reckons that the fault may now possibly be the part that the crank sensor sits in and sends signal to ECU.

Will wait and see what the outcome is and let you know.

Astra 'F'

Astra 'G'

Hope that helps.

The crank sensor theory is a good one. I toyed with it, but you said your on your second now.

Ah - now thats a result - but i think it could be that the mounting is cast and part of the block - same as the astra G - most of the time these are damaged when either the crank pulley isn't fitted right or a rock jumps off the road and *beep* it
time for some araldite methinks
cheers

Just thought i'd let you know the latest.

The crankshaft pulley wheel pin is snapped. (me thinks that's not gonna help).

That will not help things. Throw the timing out and the crank sensor doing its thing and not starting the engine. Have to admit its the first time I have heard of the Crank Sensor doing its intended job, as opposed to being knackered itself lol

It's gonna be one of the first things I check on a non start vauxhall from now on! Evil or Very Mad

Again, thank you so much for your input on this.

Got new pulley and sprocket turning up tomorrow, so fingers crossed, we (hopefully) will be up and running by the weekend.
