Technical Fiat strada 1.2 fuse box

[Strada1979]

Good day

Attached picture of my 2007 Fiat Strada 1.2 EL fuse box i side the cabin

I see according to the owners manual what all the blade fuses are for ....

I need to know what the 4 relays next to the fuses are for...also i see there are spaces for relays that is not there
Any takers?

Favourites will be :
indicators/hazards
Wipers

So Not too much guessing now

Also may have schematic on Relay to indicate likely function

Thank you

You are welcome .
We didn't get Palio, Siena or Strada.. So can only offer general advice..

No problem

I have another issue with starting the car...
I took out the fuel pump thinking it was faulty but ended up being a faulty relay
Any way....pit everything back together and now it starts...sputters and dies....
Double checked everything but still jave the problem
I am thinking of setting fire to it or push it down a cliff

Any advise on this?
Greetings

What else did you disturb..?

Does it restart instantly.. Or really struggle?

 

[Strada1979]

Nothing else i touched
It starts but the rpm is really really low...id say 300-400rpm
Idles for like 2-3 seconds and dies
Then it wont start at all for a few minutes

I checked the fuel pressure on the fuel rail and that seems fine.

I am beginning to think of fuel starvation....its not getting fuel...like i said pump works relay is fine

Will the return line fitting that i fixed not have anything to do with this? Say if its obstructed or blocked maybe?

Another question...if the battery voltage is below 12v will that also affect the pressure of the pump?

Unlikely

If it has power to crank motor is should be fine..

Next test, turn key at MAR.. how long does the tank pump run?

Should be 5 to 10 seconds..


Try running it twice, then crank.. Does motor run longer?

Hi there
Fuel pump runs 5-10 seconds...

I have tried the MAR thing but still nothing

If the voltage supplied to the pump is low, for any reason like broken wire connection or weak battery, the pump will not work as normal.

6 Factors That ​

Is the car starting with its own battery?

(Not using a booster)

FlyByWire throttles can give a similar result if power is not supplying sensors correctly

Own battery....
I have put it on charge now overnight
Will check out in the morning
