Car Won't Start

[Mrnhm]

I have a C4 sxi 1.6 petrol manual. Year 2006

 

The other day my car was fine until I returned to it after work. Remote opened the doors and all the dash lights were fine. No error message. Car wouldn't start. Just a click when the key turned. Doesn't even attempt to turn over.

 

Starter motor changed £110 later. Still no change.

 

Car will not start when jumped using leads. Car won't start when the battery is changed.

 

Car will start when pushed and jumped in gear.

 

Does anyone have any ideas? I don't have the money to keep throwing away on if buts and maybes.

 

Thank you

Update. I have run a diagnostic on the car and no fault codes have been found. STUMPED!!

Welcome to the forum.

 

A few questions -

 

- have you measured the battery voltage, since at first it sounds like a flat battery, even though it has been changed. Should be 12.5 to 12.7 volts without the engine running and about 14.4 volts when running.

 

- when trying to start, where is the click noise coming from - is it the solenoid on the starter or elsewhere

 

- when you have bump started it, does it continue to run normally

 

- the diagnostic check, was this just a code reader check or did you use a dealer type Lexia

 

- have you tried the spare key in case it is an immobiliser fault with the key

 

There is now a Haynes manual for the C4 and in the fault finding section under engine fails to rotate when attempting to start it gives

- battery terminal connections loose or corroded

- battery discharged or faulty

- broken, loose or disconnected wiring in the starting circuit

- defective starter motor

- starter pinion or flywheel/driveplate ring gear teeth loose or broken

- engine earth strap broken or disconnected

 

To this you could add

- a problem with the ignition switch

- a bad earth connection

- a problem with the engine management/sensors - but if it runs normally once bump started this may not be the case, similarly the fuel system

- check the fuses - Haynes lists in the engine fuse box fuse F8, 25 amp for the starter. Check your handbook to see if it is the same. The wiring diagram also shows a relay in the fusebox but I do not know if this can be changed.

- to by-pass the starter circuit you could try a positive supply direct to the starter solenoid to see if the starter will turn (make sure the ignition key is not in the car and the gearbox is in neutral).

- when trying to start the car you could check for a 12 volt supply to the starter solenoid.
