When cranking the engine over does the eml light flash? I believe all omegas have immobilizers

the light flashes constantly when i turn the key to on and it flashes constantly when trying to start. also the abs light flashes when trying to start it as well. i am 100% sure the car has no immobiliser they did not start using them untill 1996 its just a standard key with nothing inside the plastic bit in the key it always comes apart. any ideas ware to start looking for this problem car worked fine parked it up used it again about 2 hours later and car wont start

Have you a spare key you can try?

i only have the one key no remote locking. the key is just a normal key with no transponder inside. the plastic bit on the key always comes apart and there is nothing inside. is the injector timming run off the timming chain or the aux belt its maybe sliped a tooth

kneepad thanks for reply but your info is to technical how can i use it to proceed forword

well its some were to start kneepad i will give it a try tomorrow

if no chip in the key it wont start!! unless a previous owner has taped the chip to the ignition barrel or somewhere close
