Mercedes clk 240

[Precise786]

Whilst driving the car it just cut out and won’t start. Checked fuel pump relay and fuse, changed cam shaft position sensor, changed crank shaft sensor and still no joy. Put diagnostics machine to but not showing anything up, just seems really weird, was wandering anybody have similar problem or any ideas of what it can be. Cranking but not starting.
Many thanks

Check if there is any fuel pressure in the rail. You’ll find a cap on one end. If you unscrew it and press the tit on the end you should get a gush of fuel. If it’s just a dribble you have pump problems
