I have had starting problems. Still not cured.
And The ML stalled twice at intersections , thankfully it started tight back up those two times.

So when it wouldnt start yesterday I took off the engine plastic cover and took the cap off the fuel valve on the fuel line and pushed on the stem and had a squirt of gas come out. it appears i have pressure. But then - - When the engine was NOT running but the key ON ... there was a buzzing noise I could not pinpoint soounding like it was coming from the back of the intake manifold. Anybody ever experience this ?
