over the last few weeks been having problems with my punto starting, the green flag came out and said flat battery, then it worked fine for a week then it wouldnt even turn over, green flag said starter motor, so fitted a new starter motor, still wont even crank just clicks so i took it into the garage, they said new starter motor and new battery so paid for all that, drove it for a few days and noticed on my way back from work the speedo needle kept dropping to 0 the going back to normal speed. then the enginge light came on, i pulled over and the car, switched off and now the car wont start again, just clicking!! i live on a hill and if i roll the car in 2nd and release the clutch it will start and run fine just will not turn over at all!! im thinking i have an intermittent immobiliser fault? just wondered if anyone has a clue before i spend even more money. Its a 2006 grande punto 1.2.
any help will be greatly apreciated. Thanks in advance.

Alternator

The battery is 2 days old, would it really die that quickly?? All the electrics seem to be working fine.

check earths one on gearbox and one at back of engine

Ive started it probably 10 times since it left the garage

So thats the dash with the key in ignition. The abs light flashes on and off. Just tried to jump the car from my mates healthy car but still getting exactly the same.
Getting annoying!!!

And that's me driving at about 55-60

checked them earths yet?

To be honest I don't know what I'm looking for with that

Have you checked the alternator? Obviously not charging

I'm pretty sure its not the alternator or battery related because all the electrics work fine and tried to start it on jump leads this morning and wouldn't go. The immobiliser symbol is on and after a massive google session I'm thinking my fob transponder is knackered

Check voltage engine idling = ~14volt.

But it won't start :what:

Ok don't try to jump start the car. Replace the battery if you can with one you know it's charged and working. Then start the car and read voltage.

Cmosfxx it's a brand new battery. Worked for 2 days with no problems

Even a brand new battery without a correct charging voltage can be damaged.

I'm not saying btw that the battery/alternator is the issue here for sure, but it's well known that GPs are very sensitive when it comes to charging system.

So running I should be looking at 14v? I'll try it. Could get a reading on the diagnostic computer. Think I might have to take her to fiat (bye bye wages)

^^ I meant couldn't get a reading

Yes ~14v is the normal charging voltage.

use just one jump lead conect it from neg- on battery to some where bare metal on the engine, then see if it starts

where do you live? there are other good garages out there not just main dealers
