Sticky starter solenoid?

Do you hear any noises at all when you turn the key?

No, no noise whatsoever. No clicking or anything. Its almost as if someone has removed the starter motor. ATM it looks like whatever I do I am going to have to get someone to look at the gear selector switch as I don't have the gear to get under the damn thing and get to it.

Well the first check is to look for volts on the solenoid feed when the ignition key is turned.

^ yep, that's where I'd start - far easier than trying to get at the selector switch and will isolate the fault to the starter.

Think this is a garage job now, I wouldnt even know where to begin and thats if I could even get to the solenoid.....

On the plus side I do have a meter

Turn key...no noise....had this on a calibra and chased it everywhere, fuses, immob and it turned out as a worn ignition switch. Remove barrel then switch and start it with a screwdriver in the switch as diagnosis, key will need to be near the immob ring. £12 pattern for a new one

put car in park.
Get someone to turn key into start position.
Now get your volt meter and put one end to a good Earth and the other end on the 10mm nut in pic.
It should read over 12V If so Its likely a solenoid problem.
If not then its back to Selector switch/Ignition barrel thoughts.

You should hear a clicking if solenoid is sticky  My bet is a faulty starter with a loose wire when it is warm doesn't contact properly and when cold makes a contact can you get your hands on a starter to try.

Morning all,

Thanks everyone for you advice

Planning on using the extended weekend to try and sort this ignition issue. Going to have a look at the switch in the barrel as although it looks like I may have a problem with the selector switch it doesn't sound like this is the main problem. As I have never taken an ignition barrel out before are there any guides on OOF about doing this. Ive had a search and cant find one but sometimes forum searches don't always come up with what your looking for. Rather have a guide to follow as I don't want to f*** it up bullying it out when there's bound to be a method for doing this,

Cheers

Given its appears to be affected when its hot, I'd certainly be looking at the test Bigtime posted up with the pic

[Joiner]

Not that I don't want to perform the solenoid test, its been said that it should still make some noise even if faulty. In my situ its stone dead quiet, as if someones removed the starter motor.

No, a stuck solenoid may not even click. Hence, defo worth spending 20 mins doing that test

[Joiner]

OK, point taken TB, will do this first.

+1   do the starter test first as said it can be quiet too sorry for a slight mislead it would be better to try it first as its the easiest and most likely fault.     Just a thought how many keys and tags are there on your key bunch ?? as too many puts a strain on the barrel and will lead to problems.

Possible breakthrough?

Started this morning, took her for a five mile drive then tried it again after a couple of hours and she wouldnt start.

Did the pedal trick and I'm getting fault codes.

P1612 Immobiliser No Or Wrong Signal Immobiliser
P1613 Immobiliser No Or Wrong Signal Immobiliser
P1614 Wrong Transponder Key Immobiliser
P1614 Immobiliser Wrong Signal Received Immobiliser
P1614 Immobiliser NotProgrammed Immobiliser

Could this be as simple as a dying battery in the key fob?

Also, do not have a spare key to try this theory out.

Key does still have enough juice to unlock/lock the central locking though

If there is enough battery to send a signal it will open the doors it isn't the fob that opens the locks but the car battery, get a battery and change it as that is a very cheap mend if it is the fob.
