Technical Fiat 500 twin air not starting

[Samberlady]

Hi. My Fiat 500 twin air from 2015 won’t start at all. It is with my local garage. They have checked the plugs, battery, and had an electrician out aswell. We are all stumped as everything is in working order. Has anyone got any ideas?
Thank you.

What is It doing?
Does it turn over at all does it sound like it's trying to fire?
Any warning lights on the dash?

Was it unused for any length of time?

Hi Chris
No it’s not firing or turning over. Warning light is the engine light.

Chris means is the starter motor working ie turning the engine

No used most days.

No it’s not making any noise to start. So not even ticking over.

So you turn they key and nothing?
Any click from the start motor solenoid?

Is the interior fan working and Windows working as normal with they key in the ignition position?

Is it a manual gearbox ?

Engine oil level sensor has been reported to do this in a previous post from a 500 TA owner. Unfortunately it is deep inside the engine.

To do what..?

Firing..but not cranking?

Thanks I’ll report that back to the garage.

Thanks I’ll report that back to the garage.

A proper engine scan would be needed to identify if this has failed and I would personally on ly entrust to a fiat dealers diagnostic equipment.

I have to say I am still unclear if this is a car that the starter works on, but does not start or a car with a dead starter.

Firing..but not cranking?

A 500 owner reported on here the car which was two weeks old stopped and would not go again. After much ado, Fiat piulled the engine apart and reportly replaced said sensor and then it went again. The post was possibly in the last year. If I can find it I will post the link.

@Samberlady

The twinair uses unusual tech .. where it employs the engine oil to control the input of fuel and air into the engine..

Problems with this oil equipment can mean no 'fuel' is available ... therefore the engine cannot run

However.. the engine not physically turning on the starter is unrelated ;-)

But... if they have checked the plugs..I assume its 'cranking ' on the starter ok..just not firing

So back to the UNIAIR parts that controls the fuel and air going into the engine.

Hi all. I just wanted to say a massive thank you to you all for helping me with me car. It is finally working and back to full health. It was the oil sensor which controls the fuel input. It only just showed up in the diagnostic as it wasn’t showing before.
So thank u again. Xxx
