I was smelling fuel around the car for the last few weeks. But I thought I would deal with it at next oil change- in about 1000 miles. But last week I go to leave in the morning and the engine won't start. It cranks fine. I know glow plugs are new and in order. It almost started a few times , but wouldn't. It seemed that it was starved for fuel.
I had the car towed to my MB dealer and their diagnosis was that there was a leak at the fuel shut off valve and pressure was bleeding off. 3 other leaky fuel lines were also replaced.
The car now runs better than ever. The engine seems a bit more responsive. Just prior I was feeling a bit of a lag during hard acceleration.
I checked under the car a few times for drip spots when I started smelling the fuel and never saw a drop on the ground. So how could a leaky fuel shut off valve leak so much as to render the engine unstartable and show nothing on the ground?
Something doesn't sound right. But the car is now running like a champ.
Any insight would be appreciated.
