hi all im having trouble starting my v6.it has been intermittant untill now as in if she wont start on the first turn of the key she would start on the second or third but she always atarted,untill 2day,now she wont start at all.she turns over quick enough but just wont fire.im suspecting either the immobilser or the crank sensor what i would like to know is if it is the immobilser what would i need to change?the ecu or is there sumit else that gives probs?thanks all.

just to add i have no engine light on

You need to read the fault codes.

If it was the immobiliser then the ECU light would flash

[omegav6est]

bit worried now chaps.put the car on the fault code reader at work even tho the engine man light has never been on and got a code 55 which i think is change the ecu also got a 52 and an 80 which i cant find anywhere to tell me what that is any ideas surely i cant have to change the ecu as apart from the starting prob she runs well.

Does the EML come on with ignition?

[omegav6est]

yes it does come on and it goes out as normal,it doesnt flash either.im not really that worried at the mo cos the car is performing well but obviously there is a underlying problem that will need sorting sooner rather than later.

Might be worth clearing out all the codes if you have access to a reader, and then seeing if anything comes back are a few days.

The 52 is a code to suggest EML isn't (or hasn't been) working.

To check EML works, it should not go out until engine starts, and also the paperclip test should work.

Try something next time you go to start it.

Crank it for a few seconds with the accelerator floored.

Then start it normaly

fixed now,removed ecu blew out half a pound of fluff an crap bit of electrical terminal cleaner and hey presto car starts first time everytime without crankin and crankin and the codes are off and have stayed off....yehaaaa.thanks to everyone.

Are the Omega ECU's not a sealed solid state unit then?
