So I was driving my GT and it shut off by itself. It was running perfect, always started on 1st try.
While on the side of the road I was tring to figure out what happend. I realised that the fuel pump was not, or seems to not be working. I unpluged the outlet line of the fuel and turned the key on. No fuel came out.
Do I have a bad pump?
I looked at the fuses and they all seemed fine, but at 11pm it was hard to see with the phone light.
I also used a bit of brake cleaner on the intake to see if the car started. It did not. Is it a spark issue aswell?

So I came to you guys for help to try and fix it.
I cant seem to find a punto GT fuse diagram. The one on the car doesnt say where the fuel pump is. Checked the ones on the left side of the engine bay, but will recheck tomorow with more time.
Any help?

Immobiliser ok?


Still cranking fine?

I guess this has the fire protection system like many Fiats.

There's a switch, usually below either of the front seats, or under the centre console accessible from a footwell. Just a pushbutton. It is supposed to let go in an impact to stop the fuel pump, so preventing a fire. They occasionally pop out on bumps, especially sever potholes, although there have been reports of unexplained releases.

Handbook should show where, find it and give it a press, pump should then run fine.

I thik it is. never had issues with it. Pressed the imobilizer button and tried to start it and pressed it again and didn't star.

That's an odd statement. Factory immobiliser is built in, nothing to do except turn key, system will read key chip.

If you have an extra immobiliser button, this suggests someone has added an aftermarket immobiliser. If that has failed, you're in the poo until you find a way to remove it and reset to standard.

What I meant was that I clicked the button on the Key.
I found the switch for the fuel Pump. Pressed ir, and still wont fire.

This photo shows the relays for the fuel pump under the cover .
It could be the fuel pump has failed, i had one fail and the car just stopped, did the pump sound noisy when the car was running?

Did a Blink test came with this code
1256 - RPM/crank sensor - N.B. for some ECUs, this may occur if the engine isn't running and may be ignored - so ignore if you have no running issue.

Its the big black square right.
No the Pump didn't made one sound, at least One that I heard

crank sensor is by the bottom pulley.

not the black one it’s the first one of the smaller Bosch ones [emoji1303], my pump was very noisy before it failed, due to a rusty tank .

I took out the fuel Pump and tested it. The Pump works
Must bem the fuse?

Or other power issue...

looking at the diagram in the book there is a separate fuse for the pump , one of the small red ones , yours is set out slightly different .

Its a portugueses left hand drive car
I reconected the fuel Pump out of the rank just to see if it would prime when the Key is on the on position. It doesn`t. Should it make a sound?
I swapped around the fuses and still nothing

It should run for a second to prime up the system, think the smaller relay does this , once the engine is cranking the other takes over .

It does nothing. Not a sound

Try swapping the the two smaller relays over , they are the same .

Buttons on key are for the locking, not relevant to immobiliser.

I had been told that that button was the imobilizer button... I never tried it... Always locked the car manually :bang:
