Car will not start

Hello,

Just so that we cover the basics, have you tried to jump start it?
It is possible to have a discharged battery that is causing the no start.
Also, you want to make sure the battery cable is secure and free of any corrosion.

Take a look at this guide:

Typically, if there is a discharged battery you will have no sound no click or anything when trying to start.
If the starter were the issue, then you will get some clicking noise.

Let me know if it makes any clicking noise when you try to jump start it.
Thank you.

No, tried jump starting it, battery brand new and fine, also the earth wire to car is fine and no corrosion.

If the battery is good and the cables are secure, but you are still not getting anything while trying to start. This could be due to a weak connection or corrosion inside the ignition switch.

Also do you have any security light flashing? I wonder if the anti-theft got triggered.

Battery is good earth lead is fine, tried jump starting it nothing, but did notice flashing light, if it's the anti-theft that's been triggered. how to solve this issue?

Try this:
Hold the panic button on the key fob for 2 seconds. Close all of the doors and while using the key lock and use the key to unlock the lock the driver's door. If that doesn't work remove the negative battery cable for 15 seconds and reconnect.

When I tried that with the key, then opened the door and the alarm went off, so had to press the unlock on my fob.

You will have to use the fob when trying to reset the security system. Disconnecting the battery can also help.

Disconnect the battery overnight, reconnected it, used fog to open door, theft light blinking as normal, key in ignition, tried to start and still no crank or start, and theft light flashing faster now.

It is possible that you could have a faulty anti theft module.
You might want to use a scanner (capable of retrieving immobilizer codes) to get the fault codes and see what they are.
On this vehicle the anti theft is part of the General Electronic module (GEM).

I will try that, checked all fuses and there fine, the starter sensor is fine, reprogrammed key fob also.

If all those basic components are good and checked then the issue could be within the module.

What module are you talking about?

The anti theft, which is part of the General Electronic Module (GEM).

Not sure where that is, checked the starter module but that's fine.

It's on the passenger side behind the instrument panel. See diagram below.

No, it's to do with the immobilizer.

The immobilizer is part of the GEM module. Anti-theft if one of the many functions of the GEM module.

Still no further forward with this, would it be better getting a diagnostic check done?

That might be a reasonable step, it could help point to the right direction.

Thanks.

Let me know what you find out.

Will do, doing my head in.

Sounds good.
