Hi. This is my 1st post on this website although I have been a member for a couple of years. I am, by no means, a mechanic and only attempt the simpler fixes. Yesterday morning, I went out to my Mondeo and all seemed ok.

 

Doors unlocked, put key in the ignition, turned to position 2, all dash lights came on, with some going out as normal, but when I turned key to start, absolutely nothing. No clicking, no whirring, no sound of any kind.

 

No warnings came up on dash, no new warning lights came on of any kind. It seemed if the immobiliser was on, but when I turned off and took out the key, the immobiliser light in the top centre of the dash, came on as normal and continued to flash steadily.

 

It had been used, without a hitch, two evenings before, with no sign that anything was wrong.

 

Before I call my local garage, can anyone on here give me a possible reason for this to happen, i.e Starter motor has just failed ?

 

Any pointers would be gratefully appreciated.

 

Best Regards and Stay Safe everyone.

Which engine does your car have?

[merc1172001]

It is a 2.0 Duratorq tdci. Hope this is what you need ?

Hi by any chance do you have OBD2 code reader, it may give you a fault code to look up ?

No, I afraid not. I will give my son a call in case he knows someone who does have one.

If he does not, you could get a cheap one from ebay (£20 ish for a USB) and try linking it up with the free version of forscan to see what errors come up. However, to be honest, your local garage may also have relevant reader - if your going to call them anyway.  

 

For what its worth I will guess - you are right its the immobiliser given you have power from the battery.

Yes that’s fine. First thing I would check is battery condition/voltage and then the switched feed for the stater motor to engage at the stater motor solenoid itself. Plus good power and earth for the starter motor to operate. If these are good, a fault code scan is next and then any relevant codes to be acted on.

Chances are it’s hopefully just starter motor dead.

Do you have a second key for the vehicle?

There is a possibility that the battery in your keyfob has dropped below nominal voltage to the extent that the vehicle can no longer detect it in order to disarm the immobiliser.

Pure speculation of course, but it would be the first thing that I would want to rule out - particularly as I've had security system issues on my 'other' car - although it's a completely different system that relies on physical connections that wear over time, keyfob batteries will need replacing over time, and, to be fair, is the cheapest and easiest problem to resolve.

If the problem was your starter, I would expect it to have been giving you warning signs for a while - I had a starter fail on my Sierra Sapphire many years ago. They don't usually suddenly stop working.

Have you that your fuses are all good?

 

The problem with a lot of these faults is that people tend to jump to conclusions and start to make assumptions without going through a logical diagnostic process. 

You could, for example, assume it's the starter and replace it, only to find that the problem remains.

Regarding this model, the keys battery voltage does not have any connection with the cars ability to read the key to enable start. That being said, a second key could rule out a key fault but the car will usually state “immobiliser active” should this be the case.

Replacing the starter motor without any testing is, as you say, not logical and could be an expensive guess.

Possibly the key switch I mean not the key barrel but the collar I cant recall the name of it sorry about that but the key barrel comes with a electrical switch it’s got 4 spade pin switch
