Have you taken the key apart lately - for a new battery?
and lost the plastic transponder that just clips in?

that said, im sure the immob light flashes for an immobilser problem.

Have you done a pedal trick to check for fault codes on the car?
if not, do so and post up the results (instructions in my sig)

Sounds like a simple flat battery to me.

Have you tried jump starting it?

As for the alarm, check the bonnet swithc is ok and not bent

buy a new one from Vauxhall, and fit,

1 end under the scuttle, one end by the oil filter.

route cable behind the abs pipes rather than original route to protect from heat.

These do cause the failure you experiencing.

Not sure your other codes are valid, but the crank sensor one is, and suits your issues.

dont waste your money on garages...and pattern parts, buy one from VAUXHALL only and fit yourself.

Green flag mechanic  had a bit of a job to find sensor, but thanks to Mr. Greedy and other membershe found one end near the oil filter and gave it a tap and bingo... engine started..... Is this likely to play up again? should I  buy another cable?  many thanks

Seriously mate change it as i guarantee it will leave you in the shite! like halfway round a roundabout, fast lane at 70 etc etc and the engine just dies. About £65 without a trade card and 10 mins to change. I carry a spare in the boot

That crank sensor WILL let you down, VERY soon. Replace with a genuine part ASAP.

You were right, drove to garage for fuel, then a mile to my daughters, had some tea , came out, exactly the same,   I will ring Vauxhall garage in the morning as I have no vauxhall spares stockist nearby, and I dont think I could fit it as the mechanic had a jack and I havent and the car is pretty low,  the mechanic could not fint the top connection, he doesnt repair many omegas.......

car been to garage to fix crank sensor today about £150 for new sensor and labour, I could not fix it myself as I am a poor mechanic and have no tools, jack etc and as I am going on holiday on Sunday I didnt have much choice, ... can anyone explain to me  ( a real layman) what a crank sensor does please , I asked the chappie at the garage and either he didnt know or explained it very badly it must be fairly important  as the car wouldnt start whenit malfunctioned and cost £150 to put right

It's a modern day version of a distributor. It tells the engine's ECU when to fire the spark plugs ie it knows when top dead centre is & every other degree in between.  :y :y
