Hi guys, been a while since i posted last, so bit of a long one but bear with me please, got shot of my old corsa B for Corsa C SXi, been ne bother up till now, due to the rubbish weather it has not been run since 23rd December, went to start it yesterday to take it for a good blast to get the battery up to speed and no go, it started for like 2 seconds and then died, at the time i put it down to being a dead battery due to the cold, so i got the jump start kit out and connected it up, turned the ignition to position 2 to get a booster charge, the engine exhaust emissions symbol warning light was flashing on and off and there was a ticking noise like a bomb for about 5-10 seconds then the light went out and ticking stopped, at which point i turned the ignition to position 3 and the car started fine with no problems.

Took it to get some fuel and then it started up no problem, went out for a 20 mile drive to our local shopping centre and after a few hours came back and it started up no problem, come to this morning and it was just turning over and over, i thought it was a flat battery again, but after checking with a battery tester it is showing full charge, so after scratching me head for a bit i did some checking online and from hearing others it began to dawn that it could be an immobiliser issue as it starts but only for a second, this has been confirmed as when i switch the key to position 2 and leave it for about 15 seconds, the ticking noise is heard again and the engine electronics and exhaust emmisions symbols flashes for a bit until the engine electronics one goes out, at that point when i turn to position 3 it again fires but only for like a second, is there anyway this can solved without going to a dealer or is it best to just bite the bullet and get a dealer to sort it asap, cheers guys and soz for the essay!

All I can suggest is to check ecu connections are tight and dry also double check the ecu earth and battery earth, other than that main dealer.

Had someone take it in to a garage today where they said it was the crankshaft sensor, so this was replaced and the car was brought back, when i came home from work n went to test me motor it now wont start at all, so either they have replaced the crankshaft sensor with a faulty one or its something else, either way am going back to the garage tomorrow not well pleased al be getting a refund as well as saying fix me damn car, again!

Did they read any stored fault codes or just guess it was the crankshaft sensor, was the motor driven back from the dealers, maybe the connection is loose on the new sensor they fitted if it was new? and fitted?.

Cos of the shitty times i work and working the next city over am never here when the place is open and the person i had take the car in didnt say, i am assuming they assumed it was the crankshaft sensor and just replaced it, yea it was driven back home from the garage, once its been a run a little itl start up no problem, but getting it started in the first place is a damn near impossible, garage couldnt fit it in today, so itl be monday before can get it in and sorted (again) hope i dont have a fight on me hands to get it sorted and get me dosh back if it turns out the sensor was a red herring
