    just a suggestion. change the fuel filter or maybe the fuel injector is going bad. you could also have a hole in the fuel line causing it to **** air or a corroded fuel line.

This sounds very much like a fuel filter or fuel pump issue. I would replace the fuel filter first, not too expensive or difficult to do, and never hurts to replace them anyway.
An indicator light coming on tells me that the computer is finding something, and probably pressure related. If the changing of the filter does minimal to improve the problem, see about checking the fuel pressure under acceleration to make sure it is within limits.
I'm not familiar with the Fiat, so I'm not sure what all components we are working with here. Other things that cause this are a fuel pressure regulator (noticeable if you are fine with slight acceleration only to "bog" when you throttle heavy), catalytic converter issues (make sure it is not "plugged up" and flow is unrestricted).

My fiat 1.9 diesel not starting all filters been changed garage say fuel is congealing in filter still got same problem


Drain your fuel tank you can smell the gas if that's what happened. Replace all filters again and glow plugs after the system has been cleaned out refill with proper fuel and try to start. if that doesn't work take to dealer.

My 1.9 diesel bravo has been in the garage for two weeks not starting in morning got they said fuel is congealing changed all filters still same problem


for diesel fuel to congeal it has to be poor quality with a high paraffin content close to 0 degrees c or contaminated. I would go for contaminated from a fungus growing in the fuel. Get a sample of the fuel from the tank and if it is a grey slimy mess then that will be the fungus. All diesels use a return line from the injectors that lubricates and cools the injectors.and this hot fuel creates a humid atmosphere in the tank so hat when the tank cools down the fungus grows in the condensed water. Try a wynns diesel fuel treatment product as it is pretty good at killing the fungus and cleaning the tank out.

Reverse lights not working


Check your reverse switch on the transmission to make sure its hook up . You will have to probably replace it . If you have not tried that first . Use a light meter to check the reverse switch if you have power at the plug then its the switch if theres no power then check your fuse box for blowen fuss
