I own a Punto Cabrio 1.6, it'* a FIAT engine/fuel system by GM.
It has a fuel pressure regulator, Car won't start immediately. sometimes it does.
Here'* a video:
Fuel pressure regulator looks like this:
I've replaced that part off a '96 Chevrolet Cavalier.
I couldn't notice fuel leaks. how could I check if the part is worn?
Car runs ok though, no idle problems or turn offs.
How can I check if the regulator is 2.5 or 3bar?
Is there a GM style regulator that I could buy on ebay with a pressure gauge like the universal ones so it would fit?
