I started to have a a small leak and I am trying to trace the source of the leak. (The leak appears to be form the front of the car) Also, I have had trouble starting the car lately. The weather temperature has become cold recently... I don't know it this contributes to the issue?
After the car sat for a while there would be a gas smell, much like a flooded carb. Then it would be hard to start. The Volvo tech was going to do a factory fix then checked the o-ring off the pressure regulator. It was pinched. He replaced the o-ring and I have not had this problem since. Car now has 113,000 mile on it.
Longer than normal cranking to start the engine. Rough idle. Replaced fuel pressure regulator and it fixed the rough idle and hard starting. Recommend an immediate replacement if > 80000 or at least test it.
car hestkitates to start.
My car is having a hard time starting. It starts every time after 7 or 8 cranks. If I have it off for short period it starts right up. I replaced tps. That didn't work. I did plugs too. I have no check engine light on and I just ordered a fuel pressure regulator but have not installed. I hope this works.
starts hard,
