Heya peeps, im new to this site as im now officially a corsa b driver woop woop! iv'e got a 1999 corsa b 1.0 breeze 12v. modded to the max but runs like poo hehe

When i start the car it does nothing until i turn the key back off, then i hear the relay in the passenger footwell click 3 times if i try to turn it over again while the relay is clicking it will start but only for around 3-4 seconds then the relay clicks once n the car cuts out, As i only just had it n its gotta go 4 MOT ive changed plugs, feul filter, oil filter, oil change, bearings all round, brake pads all round, wipers, ball joints etc.

Does the managment light flash when your cranking it?

[greenyscorsa]

flashes constantly until the car is started, even when im not cranking it just the ignition is on, any ideas?

Try a spare key

serious? will that make a difference and why???

if your engine managment light flashes when you turn the ignition on it means your car isnt recognising your the key, and its not turning off the imobilizer.
have you dropped your key latley or has it got wet?
try the spare key if not then you may have a fault with the imobilizer.
