Dropped my car off at the paint shop this morning and ran perfectly fine they ran it in and then ran it out and when they went to take it back in nothing won't start engine management fault is oil pressure switch but would this stop the car from running ??

they sprayed paint inside engine bay?

check the battery.

Same problem here ( please see video) any advise ?

plug it to computer, but if car ran fine before and now instantly after they are done it doesnt, odd coincidence, i think they did something and are quiet about it

A little advice guys.

If you have a problem with your car and think about asking for help on the internet, the least you can do is say which model you have, what the exact symptoms are, and if you have done something to diagnose the problem before posting on the forum.

If you didn't think of diagnosing the most basic things before posting, then there's nothing anyone can do to help you on a forum since you're way out of your depth.

Like Tad says
Did you check the battery ?
Or tried to disconnect it then try again ?
As I can see on the dash there's no informations from the engine like RPM and engine temperature

I disconnect the battery overnight, this morning Fiat employee auto electrician came along with a fancy computer, plugged and and scratched his head for a bit, then he said change the immobiliser receiver and see what happens then, if that dont work you need to change the whole ECU, computer, dials, locks,keys, petrol cap, fuse box and etc ....

does that make sense to you here ?
i also tried and connected a direct earth from the battery to the engine bay mounting bracket and then to the car chassis and that didn't work neither.

last thing i have not tried is to bypass the immobiliser by suppressing the gas pedal trick, which i can not do as I don't have the key card ( plastic card )

i dont see immobiliser light on

Changing all those parts will be very costly!!
So i have 4 questions:
1- if you disconnect the battery for 2 minutes and try again it won't start too ? Even for one time ?
2- did you check battery voltage ?
3- did you check oil pressure sensor ? Because oil pressure light is off !
4- when you turn the key to MAR did you hear fuel pump from the back and throttle body test from the front ( it sounds like teeeeeet )

Note : better to record a video for your own bravo !

I know there isnt enought of oil in the engine, I'm going to top it up now and battery voltage is 11.4 all around the car ( from lighter, from battery and then a erth from engine mount) all read the same, the reason it is low is because i have been trying to start the car over and over , the battery is not even 2 weeks old.

i hear noises coming from the car but i can not confirm it is the fuel pump, what is strange is that none of the lights coming on, no radio, no central locking, remote doesnt work, basically nothing works except the climate control and windows wipers.

New update, engine oil added, tried to start again but no luck. the video is for my own Bravo, i am adding a new video below .

why doesn't the fuel gauge move and the ambient temperature readout unavailable?
Something's wrong with your canbus.

start by unplugging all unnecessary components in your car's fuse box. maybe one of them has a short and is causing all this trouble.
Then recharge the battery and try starting it again.

If it starts, plug the fuses one by one until you find which one is causing the issue.

i will do what you said tomorrow, but its not looking so good so far, should i start with the fuse box in the cabin or inside the engine bay ?

Weird!!
Did you wash your engine with water recently?
There's something wrong with car electricity!

Start with the fuse box in the cabin.
Make sure you know which fuse goes where.

No mate, i know its pretty weird that radio, interior lights, hazards, central locking, they all have stop working.

surely some one knows if this is the ECU or the main computer, I checked the engine bay again and cleaned and sand a few earth cables, now need to recharge the battery and try again tomorrow.

one other thing where is the crank sensor located on these Bravos ?

Also opened and had a look at the fuse box inside the engine bay and everything looks dry and no signs of smoke or overheating.

the ECU looks pretty good too (physically) the pins are where they should be and no sign of water damage.

I am having a bit of hard time trying to get the ECU kit too, there isnt many of this moel ( 1.4 petrol non turbo ) on the ebay. anyone here knows a better source to get them from please ?

Thats my job for tomorrow, the battery is flat now so need to recharge it and then crack on again .

So, replacement ECU kit arrived, and also as i was removing the old parts I camo across some water damage on the Blue and Me module sockets ( see below pictures.

there was also water damage signs on the computer behind the cabin fuse box.

So after 5 hours of work, the car starts now, but it runs on 3 cylinders ( i checked there is sparks on the plug (replcaced them with new ones at the same time).

I now have 3 issues;
1. The radio is asking for a code and i dont have it is there a way around this ?
2. the dashboard is now showing 68000 miles while my car only has 52000 miles is there a way to fix this ? maybe by replacing it with the old cluster dials ?
3. the engine issue which is running on 3 cylinders, do you think my injector is gone ?

Just a quick tip tho, when changing the ECU kit, there is no need to change the key barrels or central locking if you can swap the metal key part to the replacement key it will save you the hassle of buying a fuel cap or changing the locks.
