Hi there,

I have recently got my first Omega 3 litre estate which has been stood for 8 years in a garage. I replaced the battery and the battery in the key fob and although the car turns over there is no noise coming from the fuel pump.

The guy I bought it from said it was running ok but now will not start I don't know if the immobiliser is on or not thus preventing the fuel pump from operating? and is there a way of overcoming this?

I am not asking for a how to break into a car by the way just want to get it running.

I checked the fuel pump fuse and relays all seems ok so not sure where to look next?

Also the tailgate is shut solid I have greased up the lock but any other tips for getting it open would be great


Many thanks

1st step is the paper clip test, see the maint guide section index (quick link in my sig)

Report back any codes, there are some that will stop the car starting.

Thanks for the advice I will read the link shortly

After eight years that fuel might be a bit off.
I'd be tempted to drain it out and refill afresh.

Doesn't the EML flash if the imobiliser isn't happy?

ECU runs the fuel pump when it senses that the engine is turning.

Simply switching on the ignition won't make the pump run so don't be too quick to condemn it.

Thanks for that but what is the EML Engine Management Light? what does it look like?

Cheers

That I didn't know but I would have thought you would hear the pump prime itself prior to turning over but I will what you have suggested.

Many thnks

Where abouts in Wiltshire are you ?? I might be near enough to pop over some time and try and help ??

check for codes,  half a mars bar that its cranksensor

check for codes,  half a mars bar that its cranksensor 

Got back a bit late today but did the paperclip test and got the following codes
13   O2 Sensor 1 Open Circuit
14   Coolant Temperature Voltage Low

Not sure if they would stop the car from starting though?

I will check the crank sensor tomorrow

Many thanks

Hello all,

I managed to do another paperclip test today and took my shoes and socks off so I could count properly this time as I had a feeling I cocked it up yesterday!!!

So now these are the definitely the right codes and I counted each one 3 times over to make absolutely sure.

144   Immobiliser No Signal

132   Exhaust Gas Recirculation (EGR) Valve Feedback Incorrect Signal

135   Telltale (Checklight) Voltage Low

31   No Engine RPM Signal

I know 31 basically means engine not running which it isn't (boo!!)

135 I have no idea what a telltale check light is perhaps someone could please tell me

132 Not sure why this came up as engine not running but could be an old fault?

144 The big one Immobilser no signal. On the key and fob I recieved with the car the key does lock and unlock the central locking whereas the the 2 buttons on the fob do nothing apart from flash Green or Red depending which is pressed. So I take it the battery is ok.

I have no idea how to deactivate or reset the immobilser so any help on this would be most welcome and many thanks for your patience

Check to see if the immobiliser chip is in the key, if not that may well be your problem.  If there is an immobiliser chip in the key then the ecu needs programming with a tech2.  You will have to find someone near you with one 

The EGR one is prob a loose connector or a dirty connector, give it a clean and a wiggle.  The others are nothing to worry about until you start the car

The 135 telltale light is the engine management light

HI there,

Thanks for the advice I believe the chip is in there as there is a black ring in the centre of the key but not sure how to split it open to verify it as I don't want to damage it.

It doesn't look as though it has been opened before and the previous owner never mentioned any problems with it.

I will clean up the egr valve and check the connections.

BTW how does the tech 2 procedure work?

Thanks for that I take its the flashing one when you check the codes?
