1999 Mercedes-Benz CLK320 Q&A

1999 Mercedes-Benz CLK320 Question: My CLK 320 would crank about have a revolution of Engine but will not start

The Car will turn over half a rev but will not start. After a few attempts it starts and runs as if there was never a problem, this fault has become more frequent lately. No fault indicator in the Dash. This happens very often,could it be the CPS? -
Answer 1
Possibilities- engine hydro-locked after sitting (mild headgasket leak) , low voltage/poor connection to starter. Do guage lights go very dim while trying to crank? Does the starter sound different , like it's trying to work REALLY hard to turn the engine? Bad cell in battery? -
